The EPA’s new guidance will give growers the option to use a manual herbicide for weed control.
But there’s a big catch.
It only applies to the new DEET-based spray.
The new spray will be available only for the herbicide glyphosate, which is derived from glyphosate-tolerant bacteria.
It won’t work on weeds that are naturally resistant to glyphosate.
“If you want to spray a herbicide and you spray it to kill a weed, you can’t do that,” said Chris Ragan, a professor of chemistry and toxicology at the University of Michigan.
“It is an expensive spray, so you’re going to have to invest a lot of money in a new system.”
The new rule requires a two-year registration process, which includes testing and a complete assessment of your weed.
That includes weed control technology, pest management practices, soil quality, herbicide applications, weed resistance, and how your weed will respond to different pesticides.
The EPA says it will issue guidelines on how to properly use the spray later this year.
Weed control can be costly and complicated.
But if you’re looking for a new weed control system, the EPA recommends you get a spray, spray it well, and spray it frequently.
The new rules also limit how often growers can spray the herbicides, and they won’t be able to use more than five sprayers per acre, according to the EPA.
“You’re going out there and spraying, and it’s going to be expensive,” said Scott Dickson, a weed scientist at the U.S. Geological Survey in St. Paul, Minn.
“So if you want more control, then you’re really going to need a lot more than one sprayer per acre.”
The rule also requires growers to have a weed management plan that includes: Identifying the weeds that need to be controlled, and identifying the weed that you want control over.
Using pesticides that kill only those weeds that have a resistance to the herbivore, herbicides that kill weeds that don’t have resistance, or herbicides with a specific target that the weed can’t use.
And the rules also allow farmers to have up to 10 different types of herbicides for weed management.
In some cases, these chemicals can be used in combination to control multiple weeds.
For example, a plant can use the DEET spray to kill several weeds at once.
But a different weed that grows under a different tree can use glyphosate to kill the different weeds.
And when the weed is killed by DEET, it leaves behind a residue that can contain other chemicals that may be toxic to humans.
“You can use chemicals like glyphosate to control many different types and types of weeds at the same time,” said Ragan.
“There’s a whole lot of different weeds you can use DEET to control, including some of the herbicidal herbicides.
That’s why there’s so much uncertainty around weed control.”
So what can growers do?
