Weed Resistance Punches Hot Button

Weed Resistance Punches Hot Button

Growers at Commodity Classic say they are doing everything they can to prevent resistance; aren't so sure about neighbors.

DuPont Crop Protection polled growers attending the 2011 Commodity Classic about their actions to prevent weed resistance and what they think others are doing.

More than 70 percent of growers surveyed reported they are doing everything they can to control weed resistance on their own operations. In sharp contrast, only 36 percent of respondents felt other growers in their areas were doing all that they could to prevent weed resistance.

Signaling the level of concern growers have about herbicide-resistant weeds, 64 percent of respondents said preventing weed resistance is a top priority for their operations in 2011 and 63 percent said they plan to adjust crop practices to enhance resistance prevention.

Growers responding to the 2011 Commodity Classic survey were split on whether to rely more heavily on preemergence or postemergence residual herbicides.

Among respondents, 28 percent said they plan to spend between 50 percent and 75 percent of their crop protection budget on preemergence residual herbicides, while 5 percent plan to allocate more than 75 percent of their crop protection dollars to preemergence products.

Other growers indicated they prefer to spend their crop protection dollars on postemergence residual herbicides. Nearly 30 percent said they plan to invest 50 to 75 percent of their budgets on postemergence residual herbicides and another 10 percent say they intend to spend more than 75 percent on postemergence herbicides.
