In the US, a weedkiller called carbaryl is used on nearly a billion acres of farmland, and it has been blamed for spreading a strain of weed that has killed more than half of the people it has killed.
But a small US pest control company is trying to help weed killers get the word out about their use, and they have an idea for a small, inexpensive barrier to the pest that might help prevent them from spreading: A barrier to make it more difficult for weeds to spread.
The barriers are called phytotoxicity barriers, and are designed to trap, capture and kill the microbes that cause weeds to proliferate.
They’re designed to work best in areas that have very little natural soil, like lawns, or are less than 2,000 feet (610 meters) from buildings.
“The main reason that people are afraid of phytos is because we have a lot of natural barriers to the weed,” said Tom McVeigh, chief executive of Mecanoo.
The more they grow, the more the soil is going to become infected.””
So when the weeds start to grow in a lawn, the problem starts.
The more they grow, the more the soil is going to become infected.”
The barrier works by trapping and trapping and then releasing the microbes, McVeagh said.
“When we take that soil out of the system, we trap the bacteria and that destroys the plant.”
MecanOO has been trying to use a chemical that can kill weeds.
Called phytoraphosphate (PPG), it’s commonly used in pesticides.
“Phytorphosphate is very potent.
It can kill weed cells.
It kills the soil,” McVegh said.
But in a small laboratory setting, the company tested a small molecule of PPG on two types of soil.
“They killed them in a matter of hours,” he said.
The researchers then gave them a little bit of the PPG and let them grow for six weeks, and the plants sprouted.
The scientists were then able to determine that the PEG did its job.
“When we took the soil out and sprayed it on the plants, we could tell they were getting rid of the microbes and not getting infected.
And that’s a very, very important property,” Mcveigh said.”
And so what we did is, we created a phytobacterial barrier in the field.
So that it’s much easier to put up, and that’s why we started to use it on a lot more of our plants.”MECANOO also uses the PGA-1 chemical to trap microbes.
“It kills weeds.
And it kills the microbes in the plant,” Mc Veigh said, “so the PGT [phytosagrochemical compound] is used for both phytoderma and phytophotoxin.”
Phytotoxin is the main active ingredient in carbaryl, which is used to kill weeds, according to the US Environmental Protection Agency.
It also works by killing microbes that produce an enzyme called phytochrome, which in turn is able to kill bacteria that are responsible for the development of certain types of cancers.
The phytochemicals are also used to control weeds in soil.
Mecansoo has tested its PGA 1 barrier on soil in South Dakota and Texas.
“The barrier actually stopped the growth of the weed growth on the land,” McVaugh said.
That’s important because the US EPA recently gave a green light to PGA in most of the US.
“We’ve had it for a few years now,” Mc Vaugh said, noting that he expects that to continue.
“I think it’s going to be the case that it will continue to be used for at least a couple more years.”
McVeigh said the barrier is also used in pest control on farms, where it works well because it traps the microbes from the plant’s roots.
“You want it to be as effective as possible for weed control.
You want to use the best technology possible,” Mc Veghes said.
