With so many corn herbicides on the market, choosing the right products for your operation may seem like a daunting task. That’s especially true when using ineffective herbicides leads to uncontrolled weeds competing with your corn for moisture, light, nutrients and space.
Joe Armstrong, the zonal biology leader for row crop herbicides at Corteva Agriscience, says there are several factors growers should consider before selecting a herbicide for their cornfields this year. Optimum weed control, especially when targeting herbicide-resistant weeds, requires you to understand, select and rotate the right herbicide sites of action.
Ask yourself the following four questions to help determine the type of product that will work best for your operation.
“In higher-yield situations, growers will often benefit from spending a little more on their weed control to minimize or eliminate the impact of weeds on yield and preserve every bushel they can,” Armstrong says. “If a grower can spend a little more to ensure effective weed control this year, that will be beneficial in future years by reducing the overall weed seedbank.”
After answering these questions, you’ll have a better idea of what you’re looking for in a corn herbicide program. To help find the right preemergence and postemergence solutions for your fields in 2022, you can visit the corn herbicides portfolio website from Corteva Agriscience.
Choosing an effective herbicide is an important decision that can have a big impact on corn yields in the coming season, yet it’s just as important to follow the label directions on your chosen corn herbicide.
“Reading the product label can help you apply optimal use rates to maximize efficacy, decrease the risk of crop injury and minimize carryover to rotational crops,” Armstrong concludes.
