Herbicide Application Certification

As of 2017, Arkansas farmers planning to use Engenia, Xtendimax, or Enlist Duo must have a valid pesticide applicator’s license to buy the products. The three herbicides are restricted-use, or RUPs, in Arkansas. 

Additionally, in order to apply the herbicides to Xtend or Enlist crops, all applicators must complete a specific online training module. Note: Xtendimax herbicide cannot be used on Xtend crops from April 15 to September 15.
