Phenthoate（Cat No.:R016638）is an organophosphate insecticide and acaricide widely used in agriculture to control pests such as aphids, mites, caterpillars, and leafhoppers. It acts by inhibiting acetylcholinesterase, an essential enzyme for nerve signal transmission, leading to overstimulation, paralysis, and death of target organisms. Phenthoate is applied to crops including rice, fruits, and vegetables, offering broad-spectrum protection. While effective, it poses potential risks to non-target species, aquatic life, and human health if misused. Its study is relevant in pesticide chemistry, toxicology, and integrated pest management strategies.
