Factors That Lead to Herbicide Injury
Herbicides can damage crops in many ways. Applying the wrong herbicide can damage susceptible crops, so can herbicides that drift from nearby applications, and so can excessive water runoff that contains herbicides. Herbicides also can injure crops when applicators don’t follow the application directions specified on product labels or when they spray under abnormal environmental conditions.
And, of course, herbicides can damage susceptible crops when applicators do not thoroughly clean sprayer equipment before spraying different crops. This topic was discussed thoroughly in a report published by Purdue Extension titled “Removing Herbicide Residues from Agricultural Application Equipment.” Even very small amounts of herbicide residue left in tanks, hoses, screens, fittings, or booms can seriously damage crops.
If retailers leave herbicide residues in the spraying system, they will not only pay up-front to settle the claim, but there may be other costly long-term repercussions. For example, if you damage a crop, the farmer might decide to take his or her business elsewhere. That same farmer might also tell everyone about your mistake, which could turn away potential customers. Neither of those repercussions is good for business.
