Be sure to keep accurate, written records so you can find exactly what was done the last time you or your applicator sprayed or in case you are ever accused of pesticide drift. Your records should include what state, federal, and/or local laws require. In addition, here are some items that are a good idea to include that may or may not be required by law:
- The date (of the pesticide spray)
- Accurate start and end times
- Weather conditions, including temperature, humidity, wind speed and direction
- Materials and amounts applied (including adjuvants)
- Target pests
Also, be sure to keep maintenance records (including the dates of calibration, and nozzle and tip replacement) on all spray and weather monitoring equipment that is used.
Minimizing spray drift should be a team effort between the manager, customer and the skilled applicator in the field. Good communication and ongoing training are critical elements in effectively minimizing drift.
