When you want to know what farmers are thinking, you ask them. That’s what DuPont Crop Protection did earlier in 2015, surveying more than 1,200 farmers about weed resistance issues.
Jeff Carpenter, corn and soybean herbicide portfolio manager, says awareness of problems is high, but there isn’t exactly a consensus on control strategies.
Among the results:
- 85% of respondents say they worry about controlling resistant weeds on their farms.
- 48% say they can name the mode of action (MOA) of the herbicides they use.
- 42% say they tankmix herbicides that contain multiple MOAs
“Growers understand the implications increasing populations of resistant weeds can have on their operations and are becoming more proactive by applying a full range of tools to fight resistance.”
Carpenter says herbicides aren’t the only tool in the resistance toolbox, but strategic use can play an important role in managing or delaying resistance on your farm.
“Applying a burndown plus residual herbicide program eliminates emerging weeds and keeps new weeds from developing before planting,” he says.
Carpenter also recommends keeping comprehensive scouting records to know what weeds are in fields to develop a proactive management plan.
In a separate survey, Farm Journal Media surveyed more than 1,000 farmers in 2013 and again in 2015 about the worst weed on their farm. Both years, waterhemp was listed as public enemy No. 1. Learn more about those survey results here.
