Pesticide - Wikipedia

Pesticide use raises a number of environmental concerns.Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them.

ERIC - ED201865 - Pesticide Use and Water Quality., 1981-Jan

This publication describes in nontechnical language the problem of pesticide use and how it affects water quality. It provides information on laws affecting pesticide use and the reasons for them, as well as giving directions for the proper use of pesticides. The booklet is divided into five chapters, each of which concludes with a list of study questions (answers at back of book).

The Impact of Water Quality on Pesticide Performance

Water Chemistry Impacts Pesticide Performance Since water normally is used to deliver the chemical to the tar-get pest, it should be considered the foundation for the applica-tion process. Whether the water is from a well or from a lake, stream, or pond, it may be the deciding factor between ineffective and op-timum product performance. Turbidity.
