Avoid over-spraying the ground and possible drift to reduce the risk of groundwater contamination. Leave buffer zones around sensitive areas. Establishing thick vegetation, such as turf or pasture grasses, or leaving an untreated border are two ways to provide a buffer zone between a pesticide-use or handling site and a sensitive area. Dispose of pesticides properly. Triple rinse or pressure rinse pesticide containers and return the rinse water to the spray tank.
Good planning is the best insurance against pesticide disposal problems.
Buy and mix only the amounts you need. Never dispose of pesticides or pesticide containers near a water source, in sinkholes, in abandoned wells, or where there is a shallow water. Store pesticides safely. Store pesticides in their original containers in a cool, well-ventilated, protected location away from pumps and water sources. Maintain records of pesticide use.
