Today, May 10, weed resistance management comes inside the Washington, D.C., Beltway as experts from across the country convene a National Research Council event at George Washington University. In advance of the event CropLife America and the Herbicide Resistance Action Committee issued a statement reinforcing their commitment to finding and communicating solutions to weed management and herbicide-resistant weeds.
Jay Vroom, president and CEO of CLA, says: "Events such as NRC's summit help to bring those in the agricultural and scientific communities together to develop new approaches for implementing advanced solutions to mitigate herbicide resistance on the farm. Weed adaption is not new to agriculture and will continue to occur, but providing the country's farmers and ranchers with a reliable and effective suite of products and techniques to creat an integrated weed management program will help them control and better manage this phenomenon."
A key step in fighting and preventing the problem is applicator education and training. HRAC, which is an industry-based group that facilitates the effective management of herbicide resistance by promoting understanding, cooperation and communication between industry, academia, government and farmers, aims to educate the agricultural community and incorporate best practice strategies for resistance management.
Here are the key recommendations CLA and HRAC support:
- Use multiple herbicides with different mechanisms of action that are active on the same weed species, particularly those that are most troublesome or prone to evolution of herbicide resistance;
- Combine herbicides with agronomic or cultural practices such as crop rotation, optimum variety selection/planting rates, nutrient placement, and appropriate tillage to provide a comprehensive approach to weed management;
- Apply full labeled herbicide rates at recommended weed sizes.
