Whether it is spraying the wrong field, not cleaning the sprayer sufficiently, drift to sensitive crops/plants, or taking out a garden-all of these reasons, and many more, can cause major problems. Often incidents can result in tens or even hundreds of thousands of dollars to the damaged party. NDSU has resources to help people work through this:

  1. Rich Zollinger has created, “Documentation for Suspected Herbicide Spray Drift Damage, WC-751. It is available from your county agent and at this link:
