Pyrethroids are synthetic chemicals that are structurally similar to the natural insecticides purenthrins. Scientists developed pyrethroid insecticides to have enhanced biological activity and desired physical and chemical properties relative to pyrethrins.

Toxicity: Acute oral LD50 to rats:79mg/kg Acute dermal LD50 to rats:632 mg/kg Mode of action: Pyrethroids affect the nervous system of an organism. They act by disrupting the gating mechanism of sodium channels that are involved in the generation and conduction of nerve impulses..Pyrethroids disrupt the sodium channel activation gate by keeping it in the open position.Delayed closing of the gate results in prolonged excitation of nerve fibers. Lambda-cyhalothrin causes rapid paralysis and death to insect when ingested or exposed externally. Application:It is a broad-spectrum insectide with very strong stomach and contact poisoning activity, especially effective for controlling mites. It has long time effect, swift killing action to insects and low toxicity to beneficial insects. Specification:97% or 95% min technical grade Formulation: 2.5% or 5/span> Pls feel free to contact us if have any questions.
