Chlorpyrifos is a broad-spectrum organophosphorus insecticide, which not only has the functions of contact killing and stomach poisoning, but also has a strong fumigation effect on pests. Insecticidal mechanism of chlorpyrifos: inhibiting the activity of acetylcholinesterase, resulting in the accumulation of a large amount of acetylcholine at the synaptic site, resulting in the continuous activation of the postsynaptic membrane, the long-term hyperexcitability of nerve fibers, and the death of poisoned insects due to convulsions. Can be applied to fruit trees, vegetables, rice, cotton, flowers and other crops. It can also be used to control underground pests and ectoparasites of livestock and sanitary pests.
