Description

Pyriproxyfen is a highly effective insect growth regulator (IGR) belonging to the class of juvenile hormone mimics. It is valued for its potent activity against a wide range of insect pests, particularly in their larval and pupal stages, by disrupting normal development and reproduction. This makes it a critical component in integrated pest management (IPM) programs for agriculture, public health, and animal husbandry. Its favorable environmental profile, including low toxicity to mammals and beneficial insects, further enhances its utility.

Application

• Agricultural Pest Control: Used on a variety of crops including cotton, fruits, and vegetables to control whiteflies, scale insects, leafminers, and other sucking pests.
• Public Health Vector Management: A key larvicide for controlling mosquito populations, including species that transmit diseases like dengue and Zika, in both residential and commercial settings.
• Animal Husbandry: Effective in controlling fleas, ticks, and other ectoparasites on livestock, pets, and in animal housing facilities.
• Structural Pest Control: Incorporated into baits and treatments for managing cockroach, ant, and termite infestations in buildings and stored products.
• Greenhouse and Ornamental Protection: Protects ornamental plants and greenhouse crops from destructive insect pests.
• Formulation Intermediate: Serves as a primary active ingredient for manufacturers producing various end-use insecticidal formulations such as emulsifiable concentrates (EC), wettable powders (WP), and granules.
