Be sure all containers being transported are secured. Prevent Backsiphoning - When filling any pesticide spray tank from a well or other water source, be sure the end of the hose stays above the spray solution in the tank. Backsiphoning can occur when the end of the fill hose or pipe falls below the level of the solution in the tank and there is a drop in water pressure. Use an approved anti-backsiphoning device or an air break in the water system. Properly - Frequently check and maintain spray nozzles, hoses, gauges and tanks.
Proper calibration is the key to applying accurate rates of pesticides.
Improper calibration can result in too much or too little product applied, irregular distribution and poor pest control. Inaccurate tank volumes and pressure gauges or worn nozzles also may cause improper application. Inspect application equipment before every use. If Heavy Rain Is Forecast - Pesticides are most susceptible to runoff from heavy rains during the first several hours after application. And Drift - Check the pesticide label for application precautions or restrictions during windy conditions.
