Herbicide Tolerant Crop Stewardship
Herbicide Stewardship

This online course is designed for pesticide applicators looking to better understand how to prevent herbicide injury. With an understanding of the off-target movement of herbicides and knowing which factors contribute to herbicide injury, applicators can more easily take preventative steps.

  • Identify typical injury symptoms that result from exposure to PGR or auxin herbicides.
  • Learn how to get injury diagnosis assistance.
  • Identify resources for handling injured plants and communicating with neighbors.

This training also can serve those interested in preventing herbicide injury and promoting neighbor communications in regard to these issues.
