Fate and Transport of Cotton Pesticides in the Southern United States

The application of pesticides to cotton (Gossypium hirsutum) is an important issue that affects the water quality of the southern United States. Cotton receives as much as 7 kilograms per hectare of herbicide and 5 kilograms per hectare of insecticide (Gianessi and Puffer, 1990). The heavy application of pesticides is required, especially in the humid south where weed pressure is great and the boll weevil (Anthonomus grandis) is a major insect pest. These applications of pesticides are 3 to 5 times greater per hectare than applications of pesticides to corn, yet there have been no regional studies of pesticide fate in the cotton belt.
