Identify your problem weeds before choosing products for next season's crops.
No silver bullet
No matter what the worst weeds are in your cornfields, you should weigh the pros and cons of all weed control tools, Owen says. Strategies to consider include rotating crops, herbicide modes of action, tankmix combinations and tillage practices from season to season. “Farmers tend to think in the short term, but they need to think about implementing a production system for the next five years,” he says.
“The expectation is that the industry will step in with a new silver bullet that will take care of all herbicide-resistant weeds, but that’s not going to happen,” Owen states. “There’s no new product on the horizon that will do that.”
“Farmers got themselves into this bind with herbicide-resistant weeds by getting away from the use of diverse tactics to control weeds,” says Owen, “and [using multiple techniques] is what they need to do again.”
