Rotenone and dichlorvos mixed pesticide preparation

Abstract

A rotenone and dichlorvos mixed pesticide preparation is prepared by mixing 2 wt%-50 wt% of rotenone, 0.5 wt%-50 wt% of dichlorvos, and the balance an auxiliary agent. Preferably, the ratio of rotenone to dichlorvos is 4 to 1, 2 to 1, 1 to 1, 1 to 2 or 1 to 4. The invention aims to provide the rotenone and dichlorvos mixed pesticide preparation; through reasonable mixing of rotenone and dichlorvos, the insecticidal spectrum is expanded, the pesticide efficacy is improved, the pesticide dosage is reduced, the pollution to the environment is reduced, and the rotenone and dichlorvos mixed pesticide preparation is safe and efficient.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a pesticide preparation mixed with rotenone and dichlorvos. Background technique [0002] Due to the long-term single dependence on the use of a certain type of insecticide, pests are prone to develop resistance, resulting in a sharp increase in the amount of chemical pesticides used, which not only increases production costs, but also kills a large number of natural enemies of pests and pollutes the environment, resulting in pests. rampant hazards. [0003] Rotenone is a compound derived from the root of the plant Rotenone or the leaves of edamame. It has excellent insecticidal activity and is effective against most agricultural pests. The dosage is low and it degrades quickly in the environment without harming natural enemies and other non-target organisms. It is an excellent biopesticide, but its disadvantage is instability. [0004] Therefore, a new pesticide formulation is requir...
