Tackling Growing Resistance With a Proactive Approach
Weed resistance is a growing problem across the country. On Grant Strom’s family farm, they’re dealing with tough waterhemp like many farmers in their area. After testing plants in a few fields, they found all were glyphosate-resistant and half were PPO-resistant.
“The PPO burners provide 50 percent control if the weeds have any size on them at all,” Strom explains. “We’re using dicamba, but we need another postemergence herbicide and trait technology to rotate into our weed management program. Enlist provides us an option to rotate into our program and provide weed control over the top.”
This is the first year the Stroms have experienced the Enlist™ weed control system.
“The Enlist E3 beans are looking great even after delayed planting and a dry start,” Strom says. “As for application, conditions were excellent when we sprayed. The label was clear, and we talked to Andy Asbury prior to application to ensure we were set.”
Asbury is part of the team of herbicide trait field specialists supporting the Enlist system. He conducts trainings, provides technical support and helps ensure farmers have successful applications. Strom consulted with him to be certain he used an approved tank mix with the right rates.
“We had no problems with application,” Strom says. “There’s definitely less worry in terms of suspected volatility. I didn’t notice any volatility.”
Strom layered residual products and mixed glyphosate into the tank with Enlist One™ herbicide.
“2,4-D is a great weed killer,” Strom says. “Within 30 minutes, you could see the weed control. This is the first time we’ve sprayed 2,4-D over a crop, and we didn’t see any crop injury from Enlist One. Everything looks great driving by the field now.”
The Stroms continue to scout and monitor to see if they’ll need an additional postapplication. They feel confident that the tank mix and second residual layer will provide the control they need to get the beans to canopy.
“We like the option to use glufosinate,” Strom adds. “We’ve never used it before, but it provides value. It is nice to have the option for another mode of action, if needed.”
