Used primarily as an insecticide in agricultural settings to control pests such as mites, aphids, and leafhoppers on crops. Effective in managing insect populations in cotton, fruit trees, and vegetable farms due to its long residual activity. Also applied in vector control programs to reduce populations of mosquitoes that transmit malaria and other insect-borne diseases. Its use is restricted in many regions due to environmental persistence and toxicity concerns, but it remains in limited use under controlled conditions where alternative treatments are ineffective.
