Pyriproxyfen is a high-efficiency insect growth regulator belonging to juvenile hormone analogue, core agrochemical technical raw material with long residual efficacy and low mammalian toxicity. In crop agriculture, it controls whitefly, scale insect, thrips, psylla and lepidopterous larvae on cotton, citrus, vegetable and fruit trees by blocking larva metamorphosis to mature reproductive adults, suppressing pest population reproduction radically; common formulations include 95%TC,10%EC,5%ME and suspension concentrate. For public health disinfection field, it is widely applied as larvicide in stagnant water to inhibit mosquito and fly larva development, used for dengue & Zika fever vector prevention worldwide. Veterinary sector adds it into pet external insecticide to kill flea larvae on dog and cat, replacing traditional high-toxic organophosphorus pesticides. High-purity grade serves as pesticide reference standard for environmental residue detection in water, fruits and agricultural soil via HPLC/GC analysis in third-party testing labs.

GHS: Signal Word Warning, Hazard Code H410(Very toxic to aquatic life with long lasting effects)；No skin/eye irritation to mammals, acute oral LD50(rat)>5000mg/kg, dermal LD50>2000mg/kg. Direct solid contact rarely triggers human poisoning; long-term repeated dust inhalation may cause mild respiratory discomfort, wear nitrile gloves and dust mask during bulk production and formulation processing in ventilated workshop. Strictly prohibit raw material or waste liquid discharging into river, lake and aquaculture water to prevent aquatic organism massive death; collect all leakage residues with absorbent sand following spill accident. Store separately from food, feed, strong oxidizer and acidic chemicals in airtight cool warehouse away from sunshine. Waste solid and expired finished products shall be disposed as hazardous waste following local environmental laws, prohibited random landfill or incineration without approval.
