Imidacloprid is a highly effective nicotine insecticide with broad spectrum, high efficiency, low toxicity, low residue, insect resistance, safe to human, livestock, plants and natural enemies. It has multiple effects such as touch killing, stomach poisoning and ingestion. The normal conduction of the central nervous system was blocked after the pest was exposed to the pesticides, which resulted in paralysis and death. The product has a good quick-acting effect. It has a high control effect after one-day treatment, and the residue period is about 25 days. There is a positive correlation between the efficacy and temperature. The high temperature has good insecticidal effect. It is mainly used to control insect pests of piercing and sucking mouthparts.
