Organic chemicals in soil and water, such as detergents, insecticides, herbicides, fungicides, nematocides, rodenticides, growth regulators, and defoliants, can have adverse effects on agriculture. The application of persistent insecticides to potato lands has led to residues in sugar beets grown in the same soil the following year, for which there are no tolerances. Fish have been killed in farm ponds because of drainage of insecticide pollutants. Use of heptachlor (no longer recommended) to control alfalfa weevil led to soil contamination and uptake by hay; dairy cows that ate the hay produced milk containing heptachlor. Aerial and ground application of herbicides ...(100 of 17649 words)
