In Hartbeespoort, Gauteng millions of tiny insects are hard at work, eradicating the water hyacinth suffocating the dam. It’s an invasive South American weed that, when left to bloom, depletes the oxygen in the water, killing fish and preventing boats from using the dam. For years, the Madibeng Local Municipality has tried unsuccessfully to eliminate the weed, but it always grows back. Now, scientists have introduced water hyacinth planthoppers: host-specific natural enemies of water hyacinth. But this new attempt to kill off the weed hasn’t been without controversy.

This just proves it, actual bugs work harder than the ANC
Wherever you look you see the handwriting of the ANC destroyers.
de Klerk and evil mandela
After finishing watching this video, before coming down to the comment section to express my opinion, i had the exact same thought in mind.
Wherever the anc moves, in some form or another there is a result of destruction in some way or another.
Very little to nothing is done for taxpayers, and anc is like a parasite just taking however suits them.
@@chrisbadenhorst5304 and the black people are to blind to see this and keep on voting ANC
@@eisbeinGermany The municipalities sewage infrastructures is the cause of all this. The ANC run municipalities must be held accountable.
Your problem is no one holds them accountable 👿👿👿👿👿👿, everyone complaint about the State of the country but nothing gets done ✅✅, black 🖤 people still vote evil ANC in and never will stop 🛑 voting ANC cadres
Another day, another reason not to vote ANC.
This must be the Carte Balanche SA collapse tour.
South Africa has never been a functioning state. Not ever.
@@pulepebane5679 Sure bud.
It's really sad that everyone under 40 has no recollection of how beautiful and functional RSA used to be.
@@pulepebane5679 It was a first world country.was..
All thanks to the ANC. Well done.
He is correct, treat the CAUSE, NOT the SYMPTOMS
Same thing pharmaceuticals do for us.
The vaal River is also being over run. Driving over the river you can see it fulling waterway from side to side. Also the vaal never had this plant until very recently
Best advice is to put Ammonia nitrate fertilizer so it can grow. Then it will smother itself
Sad to watch the deterioration of SA right in front of our eyes😢
The are darker days ahead. The black man is not fit to manage the continent. From Cape town to Cairo no African country is doing well. We are just destroyer
Stop watching and act.
blame it on de Klerk and evil mandela,
@@eisbeinGermany sadly Anc organisation hijacked SA; police and justice system
The need to start tackling the problem upstream. The water systems in Benoni which feed into Hartbeespoort dam and the Vaal system need to be cleared first.
The municipalities sewage infrastructures is the cause of all this. The ANC run municipalities must be held accountable.
The DA runs Tshwane
@@PhakimpiDubois-rf8bz Which river from Tshwane spills it sewage into Harties dam then??
Years of this. Sad that the dam was all but cleared until the ANC led council stopped the clearing a few years back
Nonsense: hyacinth seeds can lie dormant for 25 years. This physical removal is a way of managing the issue but short term. What is needed is a totally lateral approach to the challenge. Such as killing the plants with harmonic frequency vibrations.
Mxm
Proudly brought to you by MYANC.
Early yesterday morning I watched a Carte Blanche video showing how the anc collapsed the Knysna municipality.
This morning I learned that the anc is a MAJOR contributor to the destruction of the Haarties dam.
Seems like, wherever the anc goes, in some shape or form destruction follows down its path.
And that, to me, sounds like a big problem. A problem that must be resolved on 29 May 2024, in the elections!
yeah and Tswhane is DA? This is from Tswhane. People DIED in Tswhane from Cholera. But yeah, "ANC" -
Please bring them to Benoni and Springs. We used to spend Sunday afternoons at Murray Park (Presidents Dam) but that has been impossible the last few years
unless you address the sewerage inflow theres no point in introducing the little bug. The water will still be polluted and will ultimately be dead.
It put the issue on the map, people know about it now, and this reveals more of the rotting state as whole. So its not all for nothing.
The Jukskei river also contributes to the water Hyacinth in the dam
Just wondering, has the ANC got anything right in the last 30 years?
Julie and Team have done an amazing job. I occasionally pass through the dam.
Amazing
You can actually see the difference
Another ANC success.
"Oh my gosh I can't see "😂😂😂
Same thing happening in lakeside mall, Benoni
Only the bestest candidates are chosen to manage key infrastructure. The future. She's very bright
Carte blanche please send a journalist to visit sandf in drc
We need these hoppers in Secunda we have the same hyacinth issue
Coming from JHB…. Where they use the rivers as toilets, distbins and washing. This is seen as normal behaviour and that needs to change. Remove people squatting next to rivers amd you will not only help fix this issue but several others as well
That bugs are not helping at all the whole dam looks like a grass field when driving past
Another problem with hyacinth is that it increases evaporation 3-fold by means of evapotranspiration through the leaves. We need to conserve our water resources.
The hopper is not the only insect that feeds on hyacinth. I have tried a weevil and a moth as biocontrol agents. Both unsuccessful. Maybe with the breeding programme in place, the hopper will be more successful.
I like the way Govan presents this video
Hyacinth can also be used as animal feed
This is a very easy issue to fix...
The problem is who they going to tender the solution to...and how much public funds they gonna use.
There is a undeniably easy engineering solution to get these plants out before they spread.
@Carteblance, can this solution also be viable for the Vaal River system as this is also now becoming an issue in the Vaal River system.
Big surprise that it is the ANC's fault!
Please make a video on how we can utilize this and any kind of product can we make
Pollution also contributes to the cause of the water hyacinth in the Hartbeespoort and Tshwane Apies river around Hammanskraal
All fine, but the dead plants sink into the water and rot underwater, and the sewerage problem will be just as bad! The plant should be mechanically extracted for fertilizer. The plants have a cleansing effect, extracting polluting nutrients.
In 1985 I read statistics that said Hartbeespoort dam was the most polluted dam in the world
I hope they studied the rabbit, the emu, the toad and the rat problems in australia!
fertaliser the best possible use. several ways to take care o metals.
double its size every 2 weeks? exponential? Hmm... DOUBT.
You likely mean every two weeks it grows back to the same levels it was before they removed half of it. Exponential doubling every two weeks would have long had that hyacinth reach the moon and back!
Another question, what happens when there is no more hyacinth? The insects will just die off?
Yeah, thats why they need to breed them in 7 satellite stations. They do not self sustain.
Mutations has entered the chat.@@metalcake2288
Hi. Just a question.
Having studied biology, won't these creature evolve to become a threat?
Indeed that is a major concern. The short lifespan and the inablity to reproduce (which sadly wasn't covered in this expose), makes this an effective solution without harmful long term effects to the local bio system.
@@louriehollwhy cant they reproduce poor things lol
The problem starts with the law. The law should state that no house should be built less than 100 m from rivers. I believe there was a rule like that many years back. Now they built houses and estates on islands in rivers below flood levels etc. although environmental impact studies had been done obviously with money under the table. Things done wrong will never get right. The pollution of the Rhine river was such an example. Maybe we should learn what they have done.
Interesting to think the hopper is destroying the very environment it needs to survive!
How can we introduce some of these bugs into the lake in Centurion?
You buy them online, and introduce them lol. Throw one on and there you go, it will have food, water and oxygen.
@@user-kk4lw4mr6i Great! Where can I buy them?
"enforcement lies with the office of the minister..."... say no more.
What happens when all the plants die and sink to the bottom ?
@10:19 Please explain your statistics on cancer causing?
What about the plant under water?
Rots and some underwater stuff probably nibbles on it, fishes, etc.
Can you please bring it to Bronkhorstspruit dam. Hycinths is taking over our dam as well
Hyacinth is used as a composting base in South America - why can’t this be done in SA ?
They did adress this in this video.
Why is mechanical removal controversial? Physical removal is the only way of removing the nitrogen. The bugs don't remove the nitrogen. Huge scale compost plants could be feasible? They can mix the compost with other sources to lower the heavy metal content.
The problem is hyacinth can be purchased from almost any outlet like Woolworths!
The plant that is the focus of this video is the common water hyacinth (pontederia crassipes), native to South America. The hyacinth that you can buy in shops and nurseries is hyacinthus orientalis, which is native to the eastern Mediterranean, and is a different plant altogether. It does not grow on top of water and is not invasive
I cannot name my boeties because they keep my pockets plenty full, ne boss....
Before pointing fingers, we must first start at the root of the problem and first address the real cause of this is because someone liked an exotic plant, they’re to blame for this
Dredging that soil like the Aztecs, maya and inca did wil give you thee best fertilised soil for growing. Build a little island in the middle with that to farm food for all the houses. Do that and you help the environment.
Why not treat the cause rather than the symptoms.
Exactly!!
Sad to see that people with money brought this plant to sa cause they love the flowers
Oh, it's not the pollution of the rivers? These plants could never grow like that without the pollution
why not address the problem and control nitrates from Diepsloot and Alexandra getting into water supply, this is not a solution
Is this plant not a
Purifier .
You can have purified water, or a dead ecosystem, but you cant have both, not in Harties case anyway.
City of Tswhane (DA since 2017) and in 2022 it was DA in the City of Johannesburg. In Springs, a DA ward, the residents put their OWN water pipes in last year. In Tswhane, people died from Cholera. In False Bay, sewerage flows into the ocean (with NO distaster cause). Nelson Mandela Bay? Knysna?
The DA is TERRIBLE at water management - historically! I mean, as far back as I recall, people had to throw their sewerage in Cape Town International Airport to get services..
We need those insects in Secunda !!!
Anc the ruling party has led us into this awful mess and no one is coming forward to give us a clear thinking.We are doomed as a country.
They introduced that insect in the 70's ... just another replay ........NOT NEW .....check your records...IF they still exist ......
Megamelus was introduced to South Africa in 2013. Other insects have been around since the 70s and they contribute to the reduction of the water hyacinth as well. Because of how heavily the plants were sprayed historically the insects could not survive in high enough numbers to damage the plants. Now, between mass rearing and the cessation of spraying the insects are having an impact. The records do exist.
How to deal with the cause….thats the real problem
Hope they know what they're doing. Often, the solution is worse than the problem... Beware of the unforseen consequences...
South Africa has used biological control for well over 100 years. the same insect is being used in the USA and elsewhere as well. It's not just Harties.
Brilliant, little insects doing there thing, Water board just scared they going to loose there money given by Gov,
Turn the hyacinth into a crop. I hope that those bugs don't eat other plants when hyacinth is gone.
Pay attention to the video and you'll find out
they say the insect only lives 90 days, they have to manually reintroduce the insect after said period
When the job is done what shall we do with the insects
Eat bugs and be happy.
They die or move off to find other water hyacinth to feed on.
Bio development. Bio warfare on Hyacinth
lol show me 1 thing the ANC has turned around in 20+ years?
Please can Carte Blanche start a politically party!!! Imagine what SA coukd become with these heroes in Government 😅
How many weevils and how long do they take finish a KFC bucket full of Hyacinth?
The best thing about a politician is they are biodegradable, and sadly, politics is like social media, makes politicians spineless and unable to act, for fear of upsetting someone, something or whatever!
The hyacinths are an excellent animal and ostrich food. Animals in drought areas are dying of hunger and thirst. Carotenoids in flowers. Herbicides killed the plants...then the toxic mix sank to the bottom...fish died by the millions, the clear water was no longer filtered by the roots...
WE LIVED AT HARTEBEESPOORT DAM AT THAT TIME..changed from fishing paradise to a large developement around a sewerage system.
NB..what will the hoppers eat when the hyacinths are gone?
Pelindaba Uranium plant also contributed to massive multiplication of algae..witnesses reports...plus Jukskei river pollution from surrounding settlements.
In a healthy land, birds, especially ducks, could have assisted in controlling the hycintas, but our wildlife has gone unprotected and exterminated for human expansion purposes, leaving more harmful components to run rampant without any natural control.
The sad reality and results of a failing leadership party that provided minimal to no budgets to control the invasive species with in the borders of our amazing country. The water hyacinth is only one of to many invasives being ignored and forcing proud private citizens and establishments to stand together to rectify the failures of the same entities we trust to govern our laws and protect our basic human rights, not only for us residing currently but for the future generations to come.
They used a hippo in the 80's.
Algae follow those things I doubt a hippo will want a mouthful of algae aswell
Isn’t there a commercial benefit by harvesting hyacinth……..
We can make Natural Gas,Biofuel,Charcoal but all of the above will definitely annoy the Oil Barons.We can also use it as Animal feed and Fertilizer if it's not contaminated but again that could be competing with established markets.
Dams in East Rsnd cleared by using oxygen generators
This is yet another example of why one should always do their own research because CB is once again here to do PR for a particular group…🙄
I did research with hyacinth and Pekin ducks. The ducks refuse to eat anything else. I had to protect the hyacinth from the ducks, but I couldn't. The ducks find a way around, through, under, over, every barrier. They completely finished the hyacinth. Here's the solution: floating Pekin duck farms.
Harties dead
once the bugs are done they going to have a bug problem
Huh? They only survive on hyshit so they die obviously
well clearly those bugs are useless....
May 29th - make your vote count - get this ruling party of the majority so change can actually occur!
I guess poor people upstream laugh at the rich people downstream who are flooded by sewage.
Just emingrate
Bravo ANC you clowns
Magae is trine get himself a tender lol
Feed it to the cows
typical, don't stop the swage get another invasive to patch it up
rofl, still a poo dam , hahaha
Bsfl eats that stuff feed it to them
obviously they wont do a 100% how else are they going to get paid and money for their livestyle....just like everything in sa.
Interesting how the interviewer has a very different tone when speaking to the university lady vs the water board officials. Reeks of bias.
Wat n joke...gaan kyk nou na die dam..Vol, vol... Wat n joke....
If the minisipalety take their finger out were it not belong and repair the sewrits plants wat they are supposed to do their will no such problems
Money equals power, sadly an apartheid fault, oh how will we ever escape this power pollution.
How and what has this got to do with “apartheid”… the old fall back… ANC my friend is the cause of collapse … 30yrs in power…
Stop smoking dagga
Im sorry but this prof from the Water board has no clue what he is saying and needs to be briefed on the facts at hand. He has a very small understanding or is ignorant to the issue of the heavy metals being left in the fertiliser. THese are toxic to humans and contaminate food sources if used. It all sounds like the same story we get spun on all state issues. very very sad!
Magalies water spokesperson sounds incompetent
I blame the apartheid era??😂😂
