Abstract

The invention discloses a pesticide formulation which can control a plurality of pests like red spider and so on in citrus tree, and has killing effect. The invention contains component A of butyl ether urea and component B of fenbutatin oxide or fenpyroximate. The weight portion of the pesticide composition is that the proportion between component A and component B is 1 portion to 80 portions:80 portions to 1 portion, and the others are supplementary materials. The compound is prepared into a plurality of formulation of wettable powder, suspending agent, water dispersion granule effervescent tablet or emulsion in water and so on. The invention is characterized by low toxic, high efficiency, low pesticide residue, minor pesticide resistance of integrated control, low environment pollution, low production cost, good control effect, long protective efficacy and high killing effect. The results can be obtained that after the butyl ether urea and the fenbutatin oxide or the fenpyroximate, which have the same component, are formulated, the control effect of controlling citrus the tree red spider is above 1.5 times better than single dose of the butyl ether urea and the fenbutatin oxide or the fenpyroximate.

Description

technical field [0001] The invention relates to a pesticide insecticide and acaricide composition, in particular to a pesticide preparation which can prevent and control various pests such as citrus tree spider mite and has killing effect. Background technique [0002] At present, due to the long-term abuse of chemical pesticides in crops, the resistance of pests has increased, which has increased the cost of pest control. So far, various pests have developed resistance to many organochlorine, organophosphate, organonitrogen, carbamate and pyrethrin pesticides. Generally speaking, after many pesticides are used for a period of time (3--5 years), the control effect will decrease due to the increase of pest resistance until they are ineffective. People's resistance to pests is often the wrong way to increase the concentration and frequency of pesticide use. In fact, it is a waste to use conventional synthetic pesticides when resistance already exists. [0003] Insecticides ...
