Resistant weeds: two words growers don’t want to mention when discussing what’s growing in their fields. For many throughout the U.S., however, it’s a common statement. The International Survey of Herbicide Resistant Weeds has identified 16 weed species across 38 states that are resistant to glyphosate alone. In a time where the focus on higher yields has never been more important, the industry needs new technologies to control resistant weeds and help ensure profitability.
Among the most troublesome weeds in the U.S. are glyphosate-resistant Palmer amaranth, morningglory and waterhemp. But region by region, other weed pressures exist.
“In Arkansas, we’re seeing rising problems with glyphosate resistance in a variety of weeds,” said John Schultz, Technical Service Representative, BASF. “Additionally, growers throughout the Mid-South are struggling with pigweed resistant to PPO products [Protoporphyrinogen Oxidase inhibitors].”
In order to address weed resistance, many growers are adopting better stewardship practices such as scouting early and often to target weeds before they produce seed, rotating multiple effective sites of action, using a comprehensive weed management program that includes residual herbicides and rotating crops to allow the use of different modes of action. These measures and more will help preserve the herbicide technology that is crucial to keeping resistant weeds at bay.
However, stewardship is only one piece of the puzzle. Agriculture companies like BASF are developing new tech tools, such as Engenia™ herbicide, to help control resistant weeds. Engenia herbicide controls more than 200 broadleaf weeds, and is the most flexible and most advanced dicamba for dicamba-tolerant crops.
“Many growers have told me they’re looking forward to having another way to control weeds in-crop to address current problems in their fields,” said Schultz. “Engenia herbicide is really going to help deliver that control.”
Engenia herbicide provides an additional, effective site of action to post-emergent weed control in soybeans and cotton. It offers broad-spectrum control of broadleaf weeds like Palmer amaranth, waterhemp, marestail, velvetleaf, morningglory and giant ragweed.
To help manage weed resistance, growers should use Engenia herbicide as part of a comprehensive weed control program. Additionally, following application best practices and label directions — including proper nozzle selection, boom height settings, wind speeds and direction, buffer zone management and sprayer calibrations — will help promote on-target success of Engenia herbicide applications.
“Improved weed control is only one part of what Engenia herbicide means for growers,” said Schultz. “It’s about stewarding the land and ensuring a sustainable future for agriculture.”
By actively managing all components of application, growers can tackle resistance challenges head-on and promote clean fields. To learn more about Engenia herbicide, visit www.engeniaherbicide.com and explore the multimedia materials below.
