Problems solved by technology

For example, when rotenone preparations are used in the field, rotenone is prone to photolysis and hydrolysis in the natural environment, which affects the efficacy and persistence of rotenone, and the control effect on pests is affected to a certain extent.
As a newly listed chemical pesticide, sulfoxaflor has a good control effect on aphids. However, in order to improve the control effect of the pesticide on aphids, farmers continue to increase the dosage of the pesticide. In addition, the aphids are prone to resistance to the pesticide. sex

Abstract

The invention relates to a pesticide formulation for preventing and controlling green peach aphids, and in particular relates to an insecticidal pesticide formulation containing biopesticide-rotenone, belonging to the technical field of pesticides. The insecticidal pesticide formulation containing biopesticide-rotenone comprises the following ingredients by weight percentage: 0.1-20% of rotenone and 0.1-50.0% of sulfoxaflor, which are effective ingredients, and the balance of auxiliary agents. The pesticide formulation is in a form of microemulsion, emulsion in water or suspension concentrate. The pesticide formulation is in the form of microemulsion, emulsion in water or suspension concentrate prepared from the main ingredients, has the characteristics of good permeability, strong inabsorbability and the like, can thoroughly kill the green peach aphids in a high-efficiency manner, has low pollution to the environment and low production cost, and is suitable for chemical prevention of the green peach aphids.

Description

technical field [0001] The invention relates to a pesticide preparation for controlling peach aphid, belonging to the technical field of pesticides. Background technique [0002] peach aphid ( Myzus persicae ), also known as aphids, belongs to the family Aphididae of the order Homoptera and is widely distributed throughout the country. It is one of the main pests that harm tobacco, fruit trees and vegetables, and is also the vector of plant virus diseases. Due to the wide range of host plants and short development period of the insect, the population growth is very rapid, and the damage can be transferred to a variety of crops; the life cycle is complicated, and the plant juice is sucked, which not only hinders plant growth, forms galls, spreads viruses, but also causes flowers. , leaves, and buds are deformed. In areas where green peach aphids are frequent and frequent, chemical pesticides have been mainly used for control for a long time. Due to the continuous use of sim...
