Resistant weeds were so bad on his farm three years ago that John Malazzo only harvested 80 percent of his cotton crop that season. Today, the Caldwell, Texas, grower has found a solution to the problem in cotton with Bollgard® 3 XtendFlex® technology.
In 2018, Malazzo planted all of his cotton acres to XtendFlex® technology, keeping an eye on DP 1845 B3XF, the new variety he planted with Bollgard 3 XtendFlex technology. His weed control program was simple, based on sound recommendations and applied with a focus on detail. About 68 days after planting, he was looking at a clean crop.
“You can use this system safely and effectively, but you have to have patience because the time and the conditions have to be right in order to make a dicamba application,” Malazzo advises. “Wind speed and direction are important considerations. You also have to be aware of what is sitting downwind from the field, and sometimes that takes talking to your neighbors. Get the information beforehand and follow the label.”
2018 Herbicide Program
Last season, Malazzo used a burndown application 30 days prior to planting with Gramoxone® SL 2.0. He applied Treflan™ ahead of the planter and hoped for rainfall to activate. Weather and wind conditions forced him to make the first postemergence application of Warrant® Herbicide, Roundup PowerMAX® herbicide and XtendiMax® herbicide with VaporGrip® Technology 45 days after planting, a little later than he would’ve liked to spray.
With the application, he was targeting waterhemp, Palmer amaranth and panicum grass growing in fields. He monitored fields for weed emergence for the rest of the summer, making a second application of XtendiMax with VaporGrip Technology plus Roundup PowerMAX where needed. Malazzo attended dicamba training and monitored the RRXtend Spray App, both of which greatly helped him, he says.
“The main feature of the RRXtend Spray App that I like is getting an estimate on temperature inversion chances,” he said. “Inversion is something I did not know to check for last year. Monsanto did a good job of training us in 2018, before we went into the field, and taught us about temperature inversion risks. I think the training and the app helped to prevent a lot of issues with off-target movement in the Brazos River Bottoms region last season.”
In the end, it’s about getting good weed control and growing high-yielding cotton—and Malazzo got both with the Bollgard 3 XtendFlex varieties he planted.
It’s About Performance
“The XtendFlex technology is very effective, and the varieties perform well,” said Malazzo, who has farmed for more than 35 years. “In our on-farm cotton trials, we are seeing increases in yield potential with each new class of varieties launched. We’ve got good weed control, and yield keeps getting better.”
Unfortunately for Malazzo, before he could get his cotton harvested, Mother Nature let go an ocean of rain, delaying harvest for weeks and impacting yield in a bad way. There’s nothing he can do about it, but he plans to plant cotton again in 2019, and Deltapine® cotton with Bollgard 3 XtendFlex technology will be part of his rotation.
