Hot fogging concentrate containing pyraclostrobin and sterol synthesis inhibitor

Abstract

The invention discloses a hot fogging concentrate containing pyraclostrobin and a sterol synthesis inhibitor. The hot fogging concentrate comprises an active ingredient, an aid, a solvent and a cosolvent, wherein the active ingredient is formed by compounding pyraclostrobin and the sterol synthesis inhibitor; the content of pyraclostrobin is 1-10%; the content of the sterol synthesis inhibitor is 2-20%; and the contents of other ingredients including the aid and the solvent complement the percent to 100%. The hot fogging concentrate is suitable for hot fogging machines to spray fog and is used for controlling powdery mildew and anthracnose of such crops as fruit trees and woods. The hot fogging concentrate has the advantages of high work efficiency, synergy, good control effect, simpleness in operation, water and labor saving, safety, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a thermal mist containing pyraclostrobin and a sterol synthesis inhibitor. Background technique [0002] In arid areas, especially in hills and mountainous areas, and forest areas, the main problems encountered when using traditional methods to control pests and diseases are: lack of water, complex terrain, tall trees, and difficult operation of equipment, etc., and the efficiency is very low. And it is easy to leak and reduce the control effect. The application of hot fog has the following characteristics: [0003] 1. The droplet diameter is small, the dispersion is uniform, and the penetration is good, which increases the amount of pesticide deposition on the target crops and improves the uniformity of pesticide deposition. The amount of pesticide deposited on the crop surface is more than 30% higher than that of conventional spraying, the amount of pesticide deposited on ...

Problems solved by technology

[0002] In arid areas, especially in hills and mountainous areas, and forest areas, the main problems encountered when using traditional methods to control pests and diseases are: lack of water, complex terrain, tall trees, and difficult operation of equipment, etc., and the efficiency is very low. And it is easy to leak and reduce the control effect

[0011] At present, sterol synthesis inhibitors commonly include emulsifiable concentrates, suspension concentrates, microemulsions, wettable powders, and water-dispersible granules on the market. The long-term single and large-scale use of such active ingredients makes the bacteria develop strong resistance, which is not conducive to drug production. The further improvement of the efficacy increases the difficulty of the prevention and control of germs. It is necessary to increase the dosage and the frequency of spraying, which not only increases the labor intensity but also increases the cost of prevention and control.

In addition, the large-scale use of pharmaceuticals will inevitably lead to an increase in the amount of residues in the environment, causing certain pollution to the environment.

However, the thermal mist compounded with pyraclostrobin has not been reported at home and abroad.
