Sponsored: Attention to Detail Leads to On-Target Herbicide Application in Texas

Cotton farmer follows herbicide label to control his toughest weeds.

Cody Weishuhn farms near Mereta, Texas, in Tom Green County, an area that’s home to a lot of cotton fields. Using a traditional 2,4-D herbicide in-season customarily has been impractical. But Weishuhn had success controlling weeds without any movement by using Enlist One™ herbicide, which is a straight-goods 2,4-D choline that features inherently low volatility.

Weishuhn applied Enlist One postemergence to PhytoGen® cottonseed with the Enlist™ trait. He knew he would have to follow the label to ease concerns from his neighbors. Weishuhn was able to make multiple Enlist One applications without a single complaint from surrounding farmers.

“There was a lot of talk this year about 2,4-D applications near dicamba cotton,” Wieshuhn notes. “Neighbors haven’t seen that before and they’re still wary.”

Weishuhn farms with his father, Donald, and his business partner, Kirk Trojcak. They grow cotton, wheat, haygrazer, grain sorghum and corn while running a cow-calf operation. Cotton is an important crop for their operation. Weishuhn has planted both PhytoGen® cottonseed with the Enlist™ trait and dicamba-tolerant cotton. He says both systems offer value. 

Palmer amaranth – a type of pigweed – is the key nemesis. Weishuhn believes growers need to use all the tools available to control pigweeds. That’s why he grows both Enlist cotton and dicamba-tolerant cotton.

“I made sure to read and follow the label when applying Enlist One,” he says. “I watched the wind and was careful about weather conditions. I always made sure there was at least a 5-miles-per-hour breeze, but no strong wind. I would start spraying at 10:30 or 11:00 in the morning and spray until 2:00 or 3:00 p.m. to avoid temperature inversions.”

Weishuhn talked to his neighbors before making applications. Despite their doubts, not one reported any damage to susceptible cotton near the Weishuhn fields.

“I never had a neighbor complain,” he says. “It’s all about spraying practices.”

Weishuhn reports the weed control was excellent, even when he had to spray some weeds that were larger than he would have liked. 

“It was good not just on resistant weeds but also on volunteer cotton without the Enlist trait,” he says. “It’s a good tool to have in your toolbox to control weeds.”

Weishuhn says farmers using Enlist One need to be careful with tank mixes and make sure they’re using only approved products. He used Enlist One without tank-mixing any other products, and he believes this helped him make a successful application. “I don’t think it’s a good idea to overload the tank mix with too many products,” he says.

“In addition to Enlist One, I came back with glyphosate to control grasses,” Weishuhn says. “If you have resistant weeds, you need to use multiple tools. It takes some time. But I’d suggest not trying to add too much in the tank mix. Some guys want to save time by applying everything at once to save a trip through the field.”

Because he grew both Enlist and dicamba-tolerant cotton, Weishuhn was careful about equipment cleanout when moving from one herbicide to another. He contends effective equipment cleanout is key. 

“I enjoyed using Enlist One,” he says. “It cleaned up the fields.”

Weishuhn’s experience shows following the label and watching weather conditions allows for on-target application of Enlist herbicides even near susceptible cotton fields.
