Problems solved by technology

[0005] At present, in vegetable production, especially facility vegetable production, the frequency of occurrence of diseases and insect pests is high, the number of times of medication is high, the effect of prevention and control is poor, and the cost of prevention and control increases again.
The development of new ingredients and agents without cross-resistance to pests is costly and takes a long

Abstract

The invention discloses a pesticide combination containing pyriproxyfen, which belongs to the technical field of pest chemical prevention and comprises an effective component A pyriproxyfen and an effective component B which is one of silafluofen or ethofenprox The weight ratio of the component A to the component B is 1:15-15:1. Besides the effective components, the pesticide combination further comprises an aid and a filler, wherein the effective components A and B account for 10-50 percent of the total weight of the pesticide, the aid accounts for 10-30 percent of the total weight of the pesticide, and the balance is the filler. The pesticide combination can be prepared into a wet powder agent, or a suspending agent or missible oil. The composite pesticide has better prevention effect on vegetable whitefly, aphides, rice hoppers and the like. Compared with the conventional whitefly prevention agents, the pesticide combination has the advantages of reduction of pesticide consumption amount, reduction of environmental pollution and residues on agricultural products, long persistent period due to delaying of the pesticide resistance of the whitefly to single pesticides. Compared with the single pesticides, the invention can reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control and relates to an insecticide composition containing pyriproxyfen. Background technique [0002] Bemisia tabaci Gennadius (Bemisia tabaci Gennadius) is one of the main pests of vegetables. It often sucks the juice of plants with adults and nymphs, affects the normal growth of plants, and secretes honeydew, which induces smoke stains and seriously affects the photosynthesis of plants. , but also spread a variety of viral diseases, resulting in a serious reduction in the production of greenhouse vegetables, while also affecting the quality of vegetables. Due to the short breeding cycle of Bemisia tabaci, large number of reproduction, serious overlapping of generations, and high degree of self-fertilization, it is easy to develop resistance to pesticides, so the difficulty of control is increased, and the number of times of pesticides used in production is frequent, resulting in excessi...
