I find it harder to calibrate this way; it's hard to change someone's natural walking speed. I calibrate the sprayer to my natural walking pace, and if I need to change the spray volume, I will adjust the spray tips to get to where I need to be. This was an excellent video.

Glad it's useful Wize Guy. I've been getting questions about how fast or slow to walk with a sprayer, so now I have a public video to point to. 😎 Appreciate you watching.
Top quality content my friend. Your videos are so enjoyable to watch. I really appreciate how you explain everything in an easy way. Keep it up brother. Watching your channel from london Ontario Canada
Takes me 130 seconds to spray 1 gallon of water out of my Ryobi 4 gal 18v sprayer. I walk REALLY SLOW… or normal speed and do a second pass. But mostly really slow lol. Great video
I work in this field. This is the most important information ive seen on the internet for do it yourself people. Calibrating is super important so you dont over/underspray spray.
Im a registered technician in the state of Virginia. I essentially just do liquid and granular applications to residential until i get my next cert. I do have a little more knowledge than most at my level since my brother has been doing it for closer to a decade. I also am aware that where i live has very different types of applications than those more south or north. Living in a transition zone we have to handle both warm season and cold season grasses as well as some "weeds" from both climates. Also im always looking to learn more so if anyone has specific information on either climates i would love to hear about it as it will help me tremendously on my journey in the industry. Also i think its worth mentioning that i dont use a backpack sprayer, but i pull from a 500 gallon tank with a larger like lawnmower sized engine at 2 gallons per minute.
Even though I'm a subscriber, I wish I had found this video two days ago. I can fully confirm this is so important and little did I know how wrong I would get it. My flow rate was way too strong (new Greenworks sprayer) and my spray nozzle was also wrong.
Great video. Thanks for this. Calibration of sprayer and walking is underrated. I think that it is worth further mention that this technique needs to be applied to every tip and pressure, not one and done. This seems like the best way to apply a calibrated delivery, but there are several similar methods to allow uniform delivery of the required amount of product. This basic technique allies to manual pump sprayers as well as battery sprayers at various pressures, so long as the pressure is kept relatively constant over time, governed mainly by the tip nozzle. I really like the idea of using a phone metronome app with Bluetooth ear buds to dial in a constant pace.
You're correct Larry. If you change the spray tip or change pressures then the calibration changes. It's one of the most important steps for getting a great result that most overlook. Thanks for chiming. Appreciate you watching.
I did the walking test on my 10’ wide driveway. I measured 100’ length and the tried the 00:01:31 test. I just had to walk forward since I was able to reach left and right with the wand and gun. Way too slow on the first attempt. Better on the second try. Almost no pause in the leg movement….. might update this comment later. I think 10’ wide is a good method and comfortable reach. Also, was able to see the pavement “wet out”.
That's pretty nice sprayer! I've been dealing with the Ryobi (knowingly purchased as a beginner's budget sprayer 2-3 years ago) and it takes 300 seconds to output 1 gallon. I have to take these little half baby steps to get a proper 1 gallon sprayed to 1000 sq ft.
Ron, I have a 4 gal Chapin hand pump model Backpack sprayer. I’ve installed a pressure gauge to ensure the tank is pressurized while spraying. I find it very challenging to maintain pressure and walking pace while covering the desired area. It’s kind of like the old saying of “walking and chewing gum and trying to whistle” at the same time. LOL! I think a battery operated model would be a better choice.
Great stuff. Will be ordering a couple of those measuring pitchers. Was surprised the 115 psi setting didn't quite put out one gallon, per minute. Haven't calibrated my new Typhoon 2.5, yet. Suppose that nozzle selection has much to do with this. Also, it was a real shock to find out how difficult it is to mount 4 gallons of liquid onto my 67-year old back. Could have used a hoist.
It also depends on the nozzle trappn. My particular unit does not flow 1 gallon minute. 4 gallons is pretty heavy. I tend to put it on a table and use a bench to mount it so I'm not hoisting that much weight from the floor. Appreciate you watching!
I’m glad I watched this, I’ve never even considered timing it out. Fortunately my lawn is basically split into a 1000 and 2000 sqft section, so I just do the front and back separate.
Can also do the 18.5 ft by 18.5 ft method to figure out how much gallons per acre your sprayer puts out and adjust the herbicide amount based on your nozzle
Great channel I stumbled upon. You are a natural at this and I learn something new with every video. Can I suggest you name your channel something to do with lawn care as I am sure you are missing out on hundreds if not thousands of subscribers / views etc.
good video, I really like the editing. however, i think people put way to much into these things. Unless you have a crazy spray nozzle, its prob pretty uniform and consistent. Fill the pack up, make sure you have a well charged battery and take your time to walk the yard uniform and even. don't run, or linger around, just walk at normal pace back and forth and keep the nozzle around your knee height to maintain that max coverage. may your yard be green and your weeds be few. have a great day.
I agree with you, most spraying I've done has been professional and it's a square patch here, a narrow strip there, then there was a litre still in the sprayer before I moved to the next property etc etc - It just wouldn't be practical to try to monitor every aspect. As long as I'm putting enough down, without spraying money onto the ground then I'm happy :) Taking nothing away from the video! I understand that this is the 'proper' way to do it (and how I was taught when I had to pass a backpack spraying course for work).
@@RonHenry I hope it was taken ok bud :) I've enjoyed lots of videos on your channel and have a lot of respect for your work. (Bit of a guilty hangup that text doesn't always come across as intended!)
Great tips , def have to try the measuring now and once I get my battery sprayer upgrade , I have the Sprayers Plus 4 gallon battery sprayer and it never really held a charge properly , I got a new battery and still does not keep the charge they way other people who have it claim. Something about mine is defective. So I am just going to get a FlowZone or a Chapin soon. I know someone else mentioned on a recent vid of yours about you potentially doing a vid comparing your different battery sprayers and how you maintain and keep them in top working order. If that is still on the cards I also would be very interested in that sort of vid with me being in the market to buy a new sprayer soon.
It does make a difference Alex B. It may seem like an unnecessary step but it'll allow you to spray with more precision. Especially important when it comes to herbicide application. I'm still down to make the Flowzone vs. Chapin comparison. I've used the Flowzone for long enough now that I can point out the pros and cons.
I don't like trying to figure out how fast to walk, so I bought a tow behind sprayer. Just to lazy, plus 31 gallon tow behind wasn't much more than the battery powered backpack sprayer and I don't have to hurt my back picking up the sprayer and putting it on my back/
Actually most sprayer equipment out puts TWO gallons per minute and that's the calibration flow chart info you read on pesticide labels. If you read further on you'll find mix rates for "spot spray" applications, that's the mix rate you use in backpack sprayers along with the instructions of: "wet leaf blade" that tells you, your eyes are the best tool to use for knowing/seeing the sheen of the product. Secondly, material type you are using you may want to alter your droplet size and use a larger output nozzle to prevent spray drift and particulate "floating" thirdly and most important, the square footage rate is only important if your putting down NPK that's the primary purpose for calibration to prevent nitrogen burning of your lawn. But you wouldn't use a backpack sprayer for that since the melted urea would be too abrasive for the pump to handle. You'd use a 200 gal poly tank with like a hydro d50, Honda motor and spray applicator gun with shower type nozzle.
I guess all my sprayers are broken then. Because none of them flow 2 gallons of water per minute with the spray tips I use for lawn products.. 🤷♂️ Appreciate you watching.
@@RonHenry that's my point. The backpack pumps won't handle 2 gpm to match the flow rate calibration of the chemical mix rate on the label. That's why we use the "spot spray" application instructions on the label instead
@@patriotmjb With all due respect, I don't think you know what you're talking about. I (and countless others) blanket spray at a 1 gallon per 1000 square feet dilution rate and have done so for years with excellent results. Most lawn care products specify a dilution rate of 1 gallon of water sprayed over 1000 square feet. Off the top of my head, I can only think of a fungicide and a 1 or 2 herbicides that call for 2 gallons of water as a carrier; and that's really only required if you're not planning to water them in after application. Fertilizers, 95% of herbicides, insecticides, growth regulator, and biostimulants all recommend dilution rates starting at 1 gallon over 1000 square feet. It works great. Now if you prefer to spray at 2 gallons per 1000, fine but it would be incorrect to say it's wrong to spray 1 gallon over 1000 square feet. It's literally what I (and countless others) do every 2 weeks when I blanket spray fertilizer, biostimulants and Primo Maxx.. Appreciate you watching the content.
That's easy to be critical but what you don't realize is I'm trying to be helpful. I own one of the largest fertilizer spray companies in the state of Indiana since 2012. You're welcome for the free help. With hundreds of thousands of acres covered and millions produced in revenue I think we know about mix rates
@@patriotmjb 🤷♂ Congratulations I guess? All I'm saying is it's incorrect to say that 2 gallons per 1000 is *required* when spraying liquid products. You can get great results with a lower dilution rates. Appreciate you watching.
Yes, absolutely Willie. Different nozzles have varying flow rates. I’d pick a setting on the flowzone and do your calibration. If you change the nozzle or pressure, the calibration changes.
Duuu. After applying my brain before opening my mouth, I can see where adjusting my dilution rate with more or less water is best. I want 6.9 oz of product per 1000, so my walk speed likes 2.1 gallons + product for 205 seconds
Hi, and good afternoon. On several of your videos I think I saw you using a spray nozzle that had an angled attachment. If I'm correct would you share where I can get them. Thanks
Heya Archie. You can get them here: TeeJet AIXR11004VP: amzn.to/3fIexOD TeeJet XR11004VS: amzn.to/3iAG06O Here's a video that talks about them. th-cam.com/video/xv3KatJ4Il4/w-d-xo.html
Brother, I am going to keep commenting here how well done these are. Thank you. I appreciate you putting this knowledge out there. I will be making a point to continue through your video playlists. After a full reno with GCI Turf seed, I am need these babies to shine. Well done. Thank you. Keep up the good work. Background in turf management or just a hobby?
Glad you like them Stephen. I've worked really hard over the recent few years to improve them. Please feel free to share them with anyone that can benefit. It started out as a hobby and has turned into much more. My background is in technology field; information security specifically.
Just a fyi there are free apps available that measure your lawn for you now. Gps pulls up your house and you can click and drag for measurements across the lawn
Your videos are great. Question. Citric acid. 1 pound per 1000 square feet. How much of the product do I add to sprayer per gallon of water? Label doesn’t say.
This is why I worry about putting down some of the specialty weed killers like Tenacity (24D) or the others. How much wiggle room do I have between taking out clover, wild carrot, and crabgrass versus wiping out my yard because I got it on too heavy (even if my mixture is correct) ? I am just getting my blue grass going from last fall, have a ton of clover and wild carrot. I want to wipe that out now so I have a cleaner yard to overseed come late August as I do have plenty of bare spots. The same goes for adding liquid iron that requires 'x ' amount for 1000 sq foot. Can I get that on too thick or is there foregiveness on over doing it ?
If you follow the process shown in this video and label rates, you should be able to apply liquid products with confidence wildpony. You don’t have to be absolutely perfect, but you also can’t apply at double the rate without consequences.
Hi Ron, LOVE your presentations and appreciate your great work. QUESTION: Why not simply spray to a gallon and time that? Why all the formula? What am I missing? (I'm curious) Thanks! 2 minutes of afterthought later.....Because we're not pacing for a gallon. We're pacing for 1000 sf. (right?)....But shouldn't 1g = 1000sf when doing applications? Am I overthinking it?? [I'm a rookie. Please explain]
Heya Mr. M. You could do spray a gallon and time it. The issue is stopping at exactly 1 gallon when the sprayer is running flat out. Often times you'll put more than 1 gallon of water in or come up a bit short. simply spraying for 15 seconds and doing the math allows you to get it dead nuts perfect. Make sense?
@@RonHenry Yes Ron, thanks for replying. I went out Sunday and applied your method anyway, even after my initial response. My Petra HD4000, using a Flowzone fan nozzle that sprays at 9-10" wide timed at 87 seconds. Problem was my pace (too fast), so I have to get that down. Gonna take a lot of practice, which unfortunately looks to come at the price of a lot of backache.....I've got +23K sf. to cover, so I don't know how feasible monthly (or even twice monthly) apps are gonna work at my age and going forward. I'm considering using the 1/2 gallon per 1000 method to cover more area with less tank refills. Or, I will look into a 25g pull-behind sprayer attached to my garden tractor. Any suggestions on a good pull-behind that won't require too much maintainence? On another note: have you experienced, or heard of, issues using Prodiamine 65 WDG in a backpack sprayer? Salesman at Site One warned against using it because it clogs the sprayer - "even after vigorous mixing?" I asked. He said it requires continuous agitation to function thru a sprayer and residue will settle before I could empty the (4G) tank. Doesn't make sense to me given the agitation that comes from walking with the tank on my back. Your thoughts/experience/advice?
Great content...simple and easy to understand. Can you do a video on what to do when you have more square footage than gallons? I've got about 12,000 sq feet, so loading the sprayer up 3 times (4 gallons) is a lot of work. Can you "triple" the mixture and just spray the whole section...just know you have to walk 3X as fast?
Hi Kyle. I have 12k square feet and I do 3 fill ups. The problem with making the concentration 3x stronger is you're highly unlikely to be able to walk fast enough to get 4 gallons over 12k square feet. Even if you could, the chances of you going a bit heavy in one spot and burning the lawn goes up quite a bit vs. simply doing 3 fill ups. I wouldn't attempt to spray 12k square feet with 4 gallons of product mix.
Ron how do you effectively clean out chemicals from YM BP sprayer? Keep adding water until you spray out chemicals? I ask since you can damage your pump when tank go empty. Last ? What’s your size and measuring cup you use ? I looked it up on Amazon and the oz not clear per increment of how much to fill. I like a handle with funnel to poor. Prefer 32 or 64 oz container Thanks.
Great video! What psi are you running for applying post emergent vs pre emergent herbicide? Higher psi like 100+ for that flow rate seems really high for either application type, atleast with a fan nozzle, as the droplet size is really misty and blows extremely easily. Currently using the Milwaukee m18 switchtank, for reference. Thoughts?
I run the sprayer at the lower pressure level. The one I have only has 2 positions. I use the low. Your Milwaukee can work great as long as you calibrate it.
My 2gal pump sprayer only puts out 6-8oz with the fan tip that is on it. Can I still work with that? I have back issues and don't think I could carry a back pump. Is there another pump I can get that has a better fan tip that will put out more? The stream tip puts out 10oz but I don't think that will cover properly.
You should use the fan tip Donna. It can work well as long as you ensure you’re covering 2000 square feet with the 2 gallon product mix. Pretty much any sprayer can work as long as you’re applying the product at correct rates. To help with calibrating your sprayer, watch this video: th-cam.com/video/hg9wKPsi2pY/w-d-xo.html
Great guidance! This is the typical way this is calculated but there are a few assumptions that decrease the accuracy and chemical effectiveness. One assumption is that you have a certain amount of time to walk such that your sprayer ends up putting 1 gallon of water per 1,000 ft2. This is really inaccurate because now the chemical app depends upon your ability to accurately adjust your walking for the flow rate. What if you don’t want to walk that slow or due to terrain or age you cannot walk that fast? Walking speed should be a constant knowing that it is variable for everyone but consistent for each of us. The other assumption is that the chem to water mix must be one gallon per 1k sqft. This often doesnnot work. Some chems require a much higher dilution rate that requires a certain amount of chem per 1k sqft that can often exceed or be less than 1 gallon. Then what? Even if you could adjust your walking speed, now you are constantly adjusting that will introduce more inaccuracy. Also there is droplet size. Often you are unable to ensure a droplet size that fits the foliage or soil application while still maintaining a flow rate that meets the 1 gallon per 1,000 ft2. All being said, this is a great way to start!
Heya Vince. Agree there are several ways to calibrate a sprayer. Most products for residential lawns work well with a 1 gallon per 1k dilution rate which is why I used that as an example. If you're spraying something that requires a higher dilution rate, then adjust your pace to suit. I've not sprayed anything on my lawn that required more than 1 gallon per 1k though. Keep in mind that the rates and walking time are with the Typhoon 2 set to its higher 115psi setting. Folks that can't or don't want to walk at the pace required for the flow rates associated with that pressure can always set the sprayer to its lower setting of 70 psi. If you change tips to get different droplet sizes then you should redo the calibration. That's a big part of why I did this video using the standard green tip that's included with the sprayer. The target audience is beginners who are going to use the sprayer as it comes out of the box. Anyone that's swapping tips to alter spray pattern and/or droplet size, likely already knows how to calibrate a sprayer. Appreciate you watching. 👍😎
Or you could just make sure it's calibrated correctly as far as output and then use dye and walk as fast or as slow as you'd like. The dye will be the indicator. If the yard is covered, you'll know.
Not sure I follow. As long as your walking pace has you applying 1 gallon of product mix over 1000 square feet, you’re good to go. Using or not using marking dye won’t effect that.
Great info. What backpack sprayer do you like or recommend? I'm looking at getting a battery powered sprayer price range up to $500. I have a pump backpack sprayer but arthritis is giving me a fit spraying 35000 square feet now for 2 years.
Heya Scott. I'd go Flowzone Typhoon 2. They're tough to find in stock. You can check here: ron-henry.com/typhoon2 or on Amazon: amzn.to/39sUrVE Another good options is the Chapin 24V: amzn.to/2T22ekw The Typhoon really allows you to cover a lot of ground quickly though. Hope this helps. Thanks for watching.
Hi Jason. You'd just alter the dilution rate. So if the product you're applying can be diluted at .5 gallon per 1000 square feet, then you could effectively double the coverage and the amount of product added to the sprayer. I'd be concerned about being able to cover 1000 square feet with only half a gallon of water/product mix.
Great video, I watch another video of a guy doing a video on flow zone. I can't remember his name but he mentioned lawn Ninja's a lot also he has a real long red beard. Lol. His backpack sprayer Flow zone is able to put out a gallon of water 🌊💦 in a minute. Just wanted to know is your different from the one he has. I know they have the 5 setting type flow zone now 👍 Thanks
Not sure which Flowzone he had Eric. The idea behind showing how I arrived at those numbers is so you can calibrate your spreader. There can be variance between units so always a good idea to verify the flow rates yourself.
The green tip the sprayer comes with. You should calibrate based on the spray tip you're using. For foliar applications, this is the one I'd recommend: Foliar Tip: amzn.to/3DUCTk3
The only time you will need to do it this way, is if you are applying a product that has recommendations of needing more carrier(water) per 1000 sq ft. Since the natural walking speed of a tall person is going to be different than that of a shorter person, For a backpack sprayer calibration, it is best to skip the timing method, mark off 1000 sq feet, add couple gal to the tank, spray over that area uniformly(making sure to use the same bandwidth as much as possible on each line), then, measure how much water is remaining in the tank minus from the original amount, to give you actual amount of water used. If you used 3/4 gal of water over that area, and the product you want to use calls for 1.5 oz per 1000 sq feet, then, you know you will need 1.5 oz of product for every 3/4 gal of water that you put in the tank. Much simpler this way, and you will not need to try to conform to a certain speed of walk that you are uncomfortable with, because you have calibrated the equipment to your personal comfortable walking pace, instead of you trying to conform to a speed that the sprayer is dictating. The timing method is better suited for broadcasting with large shower heads from a tank truck. In those situations, you need time your applicators normal walking speed over a 1000 sq foot area. Then, you adjust the idle throttle on your engine or pressure regulator on your pump until you get the correct amount of water in a bucket for the amount of time that it takes that applicator to walk 1000 sq feet.
Appreciate the feedback Doug. The reason why I show this method is it reduces the math required on how much product you're adding to the tank. The viewer can literally stick to what's on the label vs. having to make adjustments. Definitely different ways of solving the same problem. Thanks for chiming in.
If I don't do this test.....Is it safe to say "roughly" 90 Seconds per 1,000 sq feet is reasonable? If not, is there a "general range?" ie, 80 to 100 seconds? (My Scotts Backpack sprayer is 4 gallons)
Thank you for the info Ron. I sprayed for clover in Mid May but still have some. Is it okay now for a second application? I live in TN and will be reseeding in Sept/Oct.
Very informative in a short time, just what most of us here on TH-cam are looking for. Well done sir.
Appreciate it Larry! Thanks for watching
I keep coming back to this video to calibrate my backpack sprayer each season, very helpful. Thank you!
Glad it’s useful!
I find it harder to calibrate this way; it's hard to change someone's natural walking speed. I calibrate the sprayer to my natural walking pace, and if I need to change the spray volume, I will adjust the spray tips to get to where I need to be. This was an excellent video.
Appreciate you watching Ryan. As long as you have a method that helps you get consistent results is all that matters. 🙏😎

Was surprised the 115 psi setting didn't quite put out one gallon, per minute. Haven't calibrated my new Typhoon 2.5, yet. Suppose that nozzle selection has much to do with this.
Also, it was a real shock to find out how difficult it is to mount 4 gallons of liquid onto my 67-year old back. Could have used a hoist.
It also depends on the nozzle trappn. My particular unit does not flow 1 gallon minute. 4 gallons is pretty heavy. I tend to put it on a table and use a bench to mount it so I'm not hoisting that much weight from the floor. Appreciate you watching!
I’m glad I watched this, I’ve never even considered timing it out. Fortunately my lawn is basically split into a 1000 and 2000 sqft section, so I just do the front and back separate.
Glad it was helpful Jason. Thanks for watching.
Can also do the 18.5 ft by 18.5 ft method to figure out how much gallons per acre your sprayer puts out and adjust the herbicide amount based on your nozzle
Great channel I stumbled upon. You are a natural at this and I learn something new with every video. Can I suggest you name your channel something to do with lawn care as I am sure you are missing out on hundreds if not thousands of subscribers / views etc.
You think it makes that much of a difference Tracy?
I use a metronome to measure my steps per minute it is a great tool for steps per 1000 sq feet.
That's definitely one method Roderick. First time hearing that one!
Okay Ron 👌 that will help me out alot... great info 👍
Glad it’s helpful man. 🙏😎
@@RonHenry 👍
good video, I really like the editing. however, i think people put way to much into these things. Unless you have a crazy spray nozzle, its prob pretty uniform and consistent. Fill the pack up, make sure you have a well charged battery and take your time to walk the yard uniform and even. don't run, or linger around, just walk at normal pace back and forth and keep the nozzle around your knee height to maintain that max coverage. may your yard be green and your weeds be few. have a great day.
Appreciate you watching Michael! Thanks for the feedback.
I agree with you, most spraying I've done has been professional and it's a square patch here, a narrow strip there, then there was a litre still in the sprayer before I moved to the next property etc etc - It just wouldn't be practical to try to monitor every aspect. As long as I'm putting enough down, without spraying money onto the ground then I'm happy :)
Taking nothing away from the video! I understand that this is the 'proper' way to do it (and how I was taught when I had to pass a backpack spraying course for work).

Great tips , def have to try the measuring now and once I get my battery sprayer upgrade , I have the Sprayers Plus 4 gallon battery sprayer and it never really held a charge properly , I got a new battery and still does not keep the charge they way other people who have it claim. Something about mine is defective. So I am just going to get a FlowZone or a Chapin soon. I know someone else mentioned on a recent vid of yours about you potentially doing a vid comparing your different battery sprayers and how you maintain and keep them in top working order. If that is still on the cards I also would be very interested in that sort of vid with me being in the market to buy a new sprayer soon.
It does make a difference Alex B. It may seem like an unnecessary step but it'll allow you to spray with more precision. Especially important when it comes to herbicide application. I'm still down to make the Flowzone vs. Chapin comparison. I've used the Flowzone for long enough now that I can point out the pros and cons.
Great video and great information

Great stuff!!
Haha. Math can be useful. Fortunately the math is pretty simple. Thanks for watching.
I don't like trying to figure out how fast to walk, so I bought a tow behind sprayer. Just to lazy, plus 31 gallon tow behind wasn't much more than the battery powered backpack sprayer and I don't have to hurt my back picking up the sprayer and putting it on my back/
Actually most sprayer equipment out puts TWO gallons per minute and that's the calibration flow chart info you read on pesticide labels. If you read further on you'll find mix rates for "spot spray" applications, that's the mix rate you use in backpack sprayers along with the instructions of: "wet leaf blade" that tells you, your eyes are the best tool to use for knowing/seeing the sheen of the product. Secondly, material type you are using you may want to alter your droplet size and use a larger output nozzle to prevent spray drift and particulate "floating" thirdly and most important, the square footage rate is only important if your putting down NPK that's the primary purpose for calibration to prevent nitrogen burning of your lawn. But you wouldn't use a backpack sprayer for that since the melted urea would be too abrasive for the pump to handle. You'd use a 200 gal poly tank with like a hydro d50, Honda motor and spray applicator gun with shower type nozzle.
I guess all my sprayers are broken then. Because none of them flow 2 gallons of water per minute with the spray tips I use for lawn products.. 🤷♂️ Appreciate you watching.
@@RonHenry that's my point. The backpack pumps won't handle 2 gpm to match the flow rate calibration of the chemical mix rate on the label. That's why we use the "spot spray" application instructions on the label instead
@@patriotmjb With all due respect, I don't think you know what you're talking about. I (and countless others) blanket spray at a 1 gallon per 1000 square feet dilution rate and have done so for years with excellent results.
Most lawn care products specify a dilution rate of 1 gallon of water sprayed over 1000 square feet. Off the top of my head, I can only think of a fungicide and a 1 or 2 herbicides that call for 2 gallons of water as a carrier; and that's really only required if you're not planning to water them in after application. Fertilizers, 95% of herbicides, insecticides, growth regulator, and biostimulants all recommend dilution rates starting at 1 gallon over 1000 square feet. It works great.
Now if you prefer to spray at 2 gallons per 1000, fine but it would be incorrect to say it's wrong to spray 1 gallon over 1000 square feet. It's literally what I (and countless others) do every 2 weeks when I blanket spray fertilizer, biostimulants and Primo Maxx.. Appreciate you watching the content.
That's easy to be critical but what you don't realize is I'm trying to be helpful. I own one of the largest fertilizer spray companies in the state of Indiana since 2012. You're welcome for the free help. With hundreds of thousands of acres covered and millions produced in revenue I think we know about mix rates
@@patriotmjb 🤷♂ Congratulations I guess? All I'm saying is it's incorrect to say that 2 gallons per 1000 is *required* when spraying liquid products. You can get great results with a lower dilution rates. Appreciate you watching.

@@Methodical2 thanks sir. I fixed the link. Appreciate the heads up.
Excellent. I guess the nozzle and flowzone setting can be used to speed up or slow down the time I have? Do you agree? Thanks willie
Yes, absolutely Willie. Different nozzles have varying flow rates. I’d pick a setting on the flowzone and do your calibration. If you change the nozzle or pressure, the calibration changes.
Duuu. After applying my brain before opening my mouth, I can see where adjusting my dilution rate with more or less water is best. I want 6.9 oz of product per 1000, so my walk speed likes 2.1 gallons + product for 205 seconds

Your videos are great. Question. Citric acid. 1 pound per 1000 square feet.
How much of the product do I add to sprayer per gallon of water?
Label doesn’t say.
Hi Andrew. If you're applying 1 lb of 1000 square feet, you'd mix 1 lb with a gallon of water.
This is why I worry about putting down some of the specialty weed killers like Tenacity (24D) or the others. How much wiggle room do I have between taking out clover, wild carrot, and crabgrass versus wiping out my yard because I got it on too heavy (even if my mixture is correct) ?
I am just getting my blue grass going from last fall, have a ton of clover and wild carrot. I want to wipe that out now so I have a cleaner yard to overseed come late August as I do have plenty of bare spots.
The same goes for adding liquid iron that requires 'x ' amount for 1000 sq foot. Can I get that on too thick or is there foregiveness on over doing it ?
If you follow the process shown in this video and label rates, you should be able to apply liquid products with confidence wildpony. You don’t have to be absolutely perfect, but you also can’t apply at double the rate without consequences.
Hi Ron, LOVE your presentations and appreciate your great work. QUESTION: Why not simply spray to a gallon and time that? Why all the formula? What am I missing? (I'm curious) Thanks!
2 minutes of afterthought later.....Because we're not pacing for a gallon. We're pacing for 1000 sf. (right?)....But shouldn't 1g = 1000sf when doing applications?
Am I overthinking it??
[I'm a rookie. Please explain]
Heya Mr. M. You could do spray a gallon and time it. The issue is stopping at exactly 1 gallon when the sprayer is running flat out. Often times you'll put more than 1 gallon of water in or come up a bit short. simply spraying for 15 seconds and doing the math allows you to get it dead nuts perfect. Make sense?
@@RonHenry Yes Ron, thanks for replying. I went out Sunday and applied your method anyway, even after my initial response. My Petra HD4000, using a Flowzone fan nozzle that sprays at 9-10" wide timed at 87 seconds. Problem was my pace (too fast), so I have to get that down. Gonna take a lot of practice, which unfortunately looks to come at the price of a lot of backache.....I've got +23K sf. to cover, so I don't know how feasible monthly (or even twice monthly) apps are gonna work at my age and going forward.
I'm considering using the 1/2 gallon per 1000 method to cover more area with less tank refills. Or, I will look into a 25g pull-behind sprayer attached to my garden tractor. Any suggestions on a good pull-behind that won't require too much maintainence?
On another note: have you experienced, or heard of, issues using Prodiamine 65 WDG in a backpack sprayer? Salesman at Site One warned against using it because it clogs the sprayer - "even after vigorous mixing?" I asked. He said it requires continuous agitation to function thru a sprayer and residue will settle before I could empty the (4G) tank. Doesn't make sense to me given the agitation that comes from walking with the tank on my back. Your thoughts/experience/advice?

The FlowZone pressure can be adjusted from 8psi to 115psi…where did you set your dial for this test?
The range of 8-115 psi is for the 2.5 version. I have the 2.0 version. It only has 2 settings. 70 psi or 115 psi.
@@RonHenry Ahh, got it. So, I assume you used the 70psi setting.
@@Methodical2 Nope. The numbers in the video are for the 115 psi setting
Great content...simple and easy to understand. Can you do a video on what to do when you have more square footage than gallons? I've got about 12,000 sq feet, so loading the sprayer up 3 times (4 gallons) is a lot of work. Can you "triple" the mixture and just spray the whole section...just know you have to walk 3X as fast?
Hi Kyle. I have 12k square feet and I do 3 fill ups. The problem with making the concentration 3x stronger is you're highly unlikely to be able to walk fast enough to get 4 gallons over 12k square feet. Even if you could, the chances of you going a bit heavy in one spot and burning the lawn goes up quite a bit vs. simply doing 3 fill ups. I wouldn't attempt to spray 12k square feet with 4 gallons of product mix.
@@RonHenry Thanks for the info!
Anytime Kyle!
Ron how do you effectively clean out chemicals from YM BP sprayer? Keep adding water until you spray out chemicals? I ask since you can damage your pump when tank go empty. Last ? What’s your size and measuring cup you use ? I looked it up on Amazon and the oz not clear per increment of how much to fill. I like a handle with funnel to poor. Prefer 32 or 64 oz container Thanks.
I run it until it's pretty much empty and then run water through it to clean out the pump and lines
@@RonHenry ok so keep adding water after initially using as much chemicals as possible. then spray it out until it’s clear water. Thanks
Hey, how do you deal with different nozzles? My fan tip and flood jet tip have different rates.
Use these tips.
Foliar Tip: amzn.to/3DUCTk3
TeeJet FloodJet Tip: amzn.to/377gMJE
Hey Ron in the beginning of the video what tip are you using???
Why not fill the container up to the 1 gallon mark and time how long that takes?
Takes longer and less precise
Great video! What psi are you running for applying post emergent vs pre emergent herbicide? Higher psi like 100+ for that flow rate seems really high for either application type, atleast with a fan nozzle, as the droplet size is really misty and blows extremely easily.
Currently using the Milwaukee m18 switchtank, for reference.
Thoughts?
I run the sprayer at the lower pressure level. The one I have only has 2 positions. I use the low. Your Milwaukee can work great as long as you calibrate it.
My 2gal pump sprayer only puts out 6-8oz with the fan tip that is on it. Can I still work with that? I have back issues and don't think I could carry a back pump. Is there another pump I can get that has a better fan tip that will put out more? The stream tip puts out 10oz but I don't think that will cover properly.
You should use the fan tip Donna. It can work well as long as you ensure you’re covering 2000 square feet with the 2 gallon product mix. Pretty much any sprayer can work as long as you’re applying the product at correct rates.
To help with calibrating your sprayer, watch this video: th-cam.com/video/hg9wKPsi2pY/w-d-xo.html
@@RonHenry thank you Ron. For some reason I cannot seem to get the calculations. I will keep watching until it clicks 😊
Thanks brother
Any time! Thanks for watching
Excllent
Appreciate it!
Great guidance! This is the typical way this is calculated but there are a few assumptions that decrease the accuracy and chemical effectiveness.
One assumption is that you have a certain amount of time to walk such that your sprayer ends up putting 1 gallon of water per 1,000 ft2. This is really inaccurate because now the chemical app depends upon your ability to accurately adjust your walking for the flow rate. What if you don’t want to walk that slow or due to terrain or age you cannot walk that fast? Walking speed should be a constant knowing that it is variable for everyone but consistent for each of us.
The other assumption is that the chem to water mix must be one gallon per 1k sqft. This often doesnnot work. Some chems require a much higher dilution rate that requires a certain amount of chem per 1k sqft that can often exceed or be less than 1 gallon. Then what? Even if you could adjust your walking speed, now you are constantly adjusting that will introduce more inaccuracy.
Also there is droplet size. Often you are unable to ensure a droplet size that fits the foliage or soil application while still maintaining a flow rate that meets the 1 gallon per 1,000 ft2.
All being said, this is a great way to start!
Heya Vince. Agree there are several ways to calibrate a sprayer. Most products for residential lawns work well with a 1 gallon per 1k dilution rate which is why I used that as an example. If you're spraying something that requires a higher dilution rate, then adjust your pace to suit. I've not sprayed anything on my lawn that required more than 1 gallon per 1k though.
Keep in mind that the rates and walking time are with the Typhoon 2 set to its higher 115psi setting. Folks that can't or don't want to walk at the pace required for the flow rates associated with that pressure can always set the sprayer to its lower setting of 70 psi.
If you change tips to get different droplet sizes then you should redo the calibration. That's a big part of why I did this video using the standard green tip that's included with the sprayer. The target audience is beginners who are going to use the sprayer as it comes out of the box. Anyone that's swapping tips to alter spray pattern and/or droplet size, likely already knows how to calibrate a sprayer.
Appreciate you watching. 👍😎
Good info
Thanks Brian
Or you could just make sure it's calibrated correctly as far as output and then use dye and walk as fast or as slow as you'd like. The dye will be the indicator. If the yard is covered, you'll know.
Not sure I follow. As long as your walking pace has you applying 1 gallon of product mix over 1000 square feet, you’re good to go. Using or not using marking dye won’t effect that.
Great info. What backpack sprayer do you like or recommend? I'm looking at getting a battery powered sprayer price range up to $500. I have a pump backpack sprayer but arthritis is giving me a fit spraying 35000 square feet now for 2 years.
Heya Scott. I'd go Flowzone Typhoon 2. They're tough to find in stock. You can check here: ron-henry.com/typhoon2 or on Amazon: amzn.to/39sUrVE Another good options is the Chapin 24V: amzn.to/2T22ekw The Typhoon really allows you to cover a lot of ground quickly though. Hope this helps. Thanks for watching.
Can you do a follow up video on calibrating backpack sprayer to spray more sq footage with the same 4 gal sprayer?
Hi Jason. You'd just alter the dilution rate. So if the product you're applying can be diluted at .5 gallon per 1000 square feet, then you could effectively double the coverage and the amount of product added to the sprayer. I'd be concerned about being able to cover 1000 square feet with only half a gallon of water/product mix.
Great tip. What tip size btw…0.5gpm?
Foliar Tip: amzn.to/3DUCTk3
Thanks. Same parameters on floodjet type?
What wand and tip upgrade was that?
It's not. The sprayer comes with it. golfcourselawn.store/products/yard-mastery-4-gallon-backpack-sprayer
Great video, I watch another video of a guy doing a video on flow zone. I can't remember his name but he mentioned lawn Ninja's a lot also he has a real long red beard. Lol. His backpack sprayer Flow zone is able to put out a gallon of water 🌊💦 in a minute. Just wanted to know is your different from the one he has. I know they have the 5 setting type flow zone now 👍 Thanks
Not sure which Flowzone he had Eric. The idea behind showing how I arrived at those numbers is so you can calibrate your spreader. There can be variance between units so always a good idea to verify the flow rates yourself.
What nozzle are you using at the beginning of this video?
The green tip the sprayer comes with. You should calibrate based on the spray tip you're using. For foliar applications, this is the one I'd recommend: Foliar Tip: amzn.to/3DUCTk3
What nozzle are you using in the beginning of the video?
The spray tip it comes with
The only time you will need to do it this way, is if you are applying a product that has recommendations of needing more carrier(water) per 1000 sq ft. Since the natural walking speed of a tall person is going to be different than that of a shorter person, For a backpack sprayer calibration, it is best to skip the timing method, mark off 1000 sq feet, add couple gal to the tank, spray over that area uniformly(making sure to use the same bandwidth as much as possible on each line), then, measure how much water is remaining in the tank minus from the original amount, to give you actual amount of water used. If you used 3/4 gal of water over that area, and the product you want to use calls for 1.5 oz per 1000 sq feet, then, you know you will need 1.5 oz of product for every 3/4 gal of water that you put in the tank. Much simpler this way, and you will not need to try to conform to a certain speed of walk that you are uncomfortable with, because you have calibrated the equipment to your personal comfortable walking pace, instead of you trying to conform to a speed that the sprayer is dictating.
The timing method is better suited for broadcasting with large shower heads from a tank truck. In those situations, you need time your applicators normal walking speed over a 1000 sq foot area. Then, you adjust the idle throttle on your engine or pressure regulator on your pump until you get the correct amount of water in a bucket for the amount of time that it takes that applicator to walk 1000 sq feet.
Appreciate the feedback Doug. The reason why I show this method is it reduces the math required on how much product you're adding to the tank. The viewer can literally stick to what's on the label vs. having to make adjustments. Definitely different ways of solving the same problem. Thanks for chiming in.
Some spots on my grass is turned btan color as the lawn in this video how do I get it back green it's been getting a lot of rain.
Without seeing the lawn it's hard to say Aluminum Crusher. Most issues with discoloration come from infrequent mowing or blades that aren't sharp.
@@RonHenry thanks for your reply... Thumbs up👍👍
Could be insect damage too, if not heat stress. Dig a small spot and look for those darned insect grubs.
Quite possible Steve.
If I don't do this test.....Is it safe to say "roughly" 90 Seconds per 1,000 sq feet is reasonable? If not, is there a "general range?" ie, 80 to 100 seconds? (My Scotts Backpack sprayer is 4 gallons)
Nope. I would calibrate
Just got the Chapin for $146 on Amazon, calibration here I go.
Niiiiiice. That's a great deal Jim
@@RonHenry any guess on run time out of the one battery it came with? Max I would ever need for one application would be 20,000 sq/f
What nozzle do you have on the sprayer when the video begins looks like an awful lot of product coming out
The standard green tip that it comes with.
Thank you for the info Ron. I sprayed for clover in Mid May but still have some. Is it okay now for a second application? I live in TN and will be reseeding in Sept/Oct.
Very welcome Fredrick. Appreciate you watching sir. If the herbicide you’re using doesn’t have temperature restrictions, then yes.
