“The most important thing for a producer to know about their weed control program is what weeds they are dealing with,” he said. “For example, are they dealing with grasses, waterhemp, pigweed – Palmer amaranth – or tough to control large-seeded species such as morning glory? Waterhemps and pigweeds, especially Palmer amaranth, have been found and confirmed to have resistance to glyphosate – Roundup, etc. – in several locations in Texas. Therefore, it is imperative that growers employ aggressive measures now in order to successfully manage these resistant weeds. “
Matocha said AgriLife Extension has tested a number of products for weed control in corn. He provided an overview of products and trial results to attendees.
“Overall, what we try to preach and make growers realize (is that) foundation residual herbicides appliedright behind the planter is integral part to combatting resistant weeds,” he said. “That also includes following up with postemergence applications that has an effective component that will control both resistant and non-herbicide resistant weeds. Ideally, this treatment should also have residual product in the tank mix that will help lengthen that control throughout the season.”
Hixson discussed a new product to come on the market in the future called Engenia.
“Engenia is our new Dicamba product that has low volatility characteristics that will be used in Dicamba tolerant soybeans and cotton,” he said. “It should be available next year on a small scale.”
Matocha said he was pleased with the large attendance and the number of inquiries.
