Keep complete and current records. Also keep maintenance records on all spray and weather monitoring equipment with dates of calibration and nozzle and tip replacement. It's important that your applicator keeps accurate written records so he or she doesn't forget exactly what was done. If there were any changes in how a field is normally treated due to conditions, location of property, etc. be sure that is recorded as well. You'll want to have complete and precise information on hand should you ever be accused of failing to minimize drift.
Pesticide drift is a solvable problem.
It starts with the applicator in the field being properly trained to recognize potential problems. It also takes a commitment from the grower or the custom applicator's manager to trust the skilled applicator when he or she says, for example, that it's too windy to spray that day. Other good sources of information are the Ohio State University Cooperative Extension bulletins on pesticide drift and related issues. Please read our online policies . Inc. All Rights Reserved.
