Used primarily as a fast-acting insecticide in agriculture and veterinary medicine. Controls sucking insects like aphids, whiteflies, and leafhoppers on crops such as cotton, vegetables, and fruits. Acts by disrupting the nervous system of insects, leading to rapid paralysis and death. Also used in pet products to control flea infestations on dogs and cats, with effects seen within 30 minutes of administration. Systemic action allows it to be absorbed by plant tissues, providing protection from within. Low toxicity to mammals and birds makes it suitable for use in integrated pest management programs.
