Many farmers report glyphosate resistance
“If a weed is present in a crop in early season, you are losing yield,” said Daniel Stephenson, Ph.D., Louisiana State University weed scientist. “Add resistance on top of it, and you are not only hurting yourself if you allow the weeds to go to seed – you are hurting yourself from here on out.”
University of Tennessee weed scientist Larry Steckel, Ph.D., said glyphosate-resistant weeds have had a big financial impact on Tennessee farmers – at least a $200 million effect on their bottom lines, he said.
“And that is very conservative,” Steckel said, “because it is not counting the fields that were tilled up and not harvested. It has had a huge impact, way above what I thought going into this six, seven years ago.”
These types of statistics are why weed scientists recommend the adoption of a more comprehensive weed management program. This includes using herbicide best practices such as employing multiple herbicide sites of action in the growing season, Westberg said.
“BASF is focused on being a farmer’s number one partner for managing weed resistance and helping them to maximize yield,” Westberg said. “That is why we provide more corn and soybean herbicide sites of action than any other crop protection company.”
BASF also is dedicated to providing the solutions, technical support and educational tools to help farmers implement a weed management program that, in addition to employing multiple herbicide sites of action, includes proactive weed resistance management, as well as planning appropriately to help ensure effective, on-target applications.
The message for today’s weed control challenges, Iowa State University’s Owen said, is straight-forward: “Do something different.”
