Used as an insect growth regulator (IGR) in agriculture and public health, Pyriproxifen effectively controls pest populations by mimicking juvenile hormone and disrupting insect development. It primarily targets eggs, larvae, and nymphs of insects such as whiteflies, aphids, thrips, and mosquitoes, preventing them from maturing into reproductive adults. Commonly applied in crop protection for vegetables, fruits, field crops, and ornamental plants via foliar sprays or soil treatments. Also utilized in public health mosquito control programs to reduce vector populations in standing water. Its long residual activity allows for less frequent applications, making it efficient in integrated pest management (IPM) strategies while minimizing harm to beneficial insects.
