Technical Field

The invention relates to an imidacloprid reduction treatment process, belongs to the technical field of pesticide treatment, and particularly relates to a degradation mode for imidacloprid.

Background

Imidacloprid is a nicotine ultra-high-efficiency pesticide, has the characteristics of broad spectrum, high efficiency, low toxicity, low residue, difficult generation of resistance by pests, safety to people, livestock, plants and natural enemies and the like, and has multiple effects of contact poisoning, stomach toxicity, systemic absorption and the like. After the pests contact the pesticide, normal conduction of central nerves is blocked, so that the pests die in paralysis. The product has good quick action, has higher control effect 1 day after being applied, and has a residual period of about 25 days. The pesticide effect and the temperature are positively correlated, the temperature is high, and the insecticidal effect is good.

Imidacloprid has good chemical stability, is not easy to hydrolyze and photolyze by sunlight in natural water, is easy to enter surface water or underground water system by the scouring of agricultural water or rainwater in the using process, is easy to exist and continuously accumulate in the natural water for a long time, causes certain harm to the ambitious environment and human body, and needs to be treated.
