This course, he noted, details the fundamentals of weed resistance management practices, such as rotating herbicides and using mixtures or sequential applications of herbicides with different modes of action – steps that can prevent resistant weeds from causing havoc in the fields.
“A cotton farmer's goal is to prevent herbicide-resistant weeds from showing up in the fields,” said Ginger Light, course author and researcher at Texas Tech University. “This course provides the farmer with information to achieve that goal."
"It gives farmers an introduction to what herbicide-resistant weeds are and the types of growing conditions that cause herbicide-resistant weeds to occur."
"This tool also explains the types of resistance and how they develop. If producers know the background information on weeds' capabilities, it will help them solve the problem of resistance more efficiently.”
Andy Kendig, a University of Missouri extension weed Specialist, said, “herbicide resistance is a major concern, and, unfortunately, it can be very complicated. This course does a good job of explaining resistance and resistance prevention so growers can take appropriate steps to prevent resistance on their farms.”
The Weed Resistance Learning Module also provides general resource information on cotton herbicides and a list of contacts in each state for producers who have questions on management practices.
