Sterilization and insecticide composition containing pyraclostrobin

Abstract

The invention relates to a sterilization and insecticide composition containing pyraclostrobin. The sterilization and insecticide composition is characterized by comprising effective components including imicyafos and pyraclostrobin in a weight part ratio of 40:1 to 1:60, wherein the total parts by weight of the effective components including the imicyafos and the pyraclostrobin accounts for 1%-80% of the total parts by weight of the preparation; the sterilization and insecticide composition can be prepared into pesticide preparations in the form of wettable powder, a suspending agent, emulsifiable oil, a micro-emulsion, an emulsion in water and water dispersible granules. Compared with a single preparation, the sterilization and insecticide composition has the advantages that the application range is wider; the sterilization and insecticide composition can be used for killing insects and preventing diseases; the imicyafos and the pyraclostrobin are compounded to enhance stability and the prevention effect on diseases and insect pests is greatly improved; the insecticide resistance of pests is obviously delayed; the repeated utilization frequency of pesticides is reduced; the use amount of the pesticides is reduced and the agricultural cost is reduced; the sterilization and insecticide composition has small toxicity and low residual amount, and is good for environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing pyraclostrobin. Background technique [0002] Imicyafos (AKD-3088) is a cyanamide heterocyclic organic compound, which is composed of asymmetric organophosphorus and cyanoimidazolidine of nicotinic insecticide, which can be used in radish, carrot, strawberry, eggplant, tomato , cucumber, melon, watermelon, sweet potato and potato and other crops, its chemical structure is: [0003] . [0004] Pyraclostrobin (also known as pyraclostrobin), the English name is pyraclostrobin, and the chemical name is 2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide. It is a new type of broad-spectrum fungicide, which has protective, therapeutic and radical effects. It has a strong control effect on powdery mildew, downy mildew, scab, leaf spot, blight and other diseases of melons and vegetables, and has a long lasting effect. , It is safe fo...

AI Technical Summary

Problems solved by technology

[0006] The mode of action of pyraclostrobin is very unique. It has high-efficiency, broad-spectrum, therapeutic, protective, penetrating, and systemic activities, and has excellent characteristics such as rain resistance and long-lasting effect. It has no interaction with other fungicides currently on the domestic market. resistance

In addition, the protective and therapeutic activity of pyraclostrobin is relatively prominent, but its permeability and systemic activity are weak, and it only has local systemic activity, which has become a major shortcoming in its mechanism of action, and it has also brought some practical problems. agricultural problems, the prevention and control of diseases is not stable enough, etc.

If a single insecticide or fungicide is used for a long time, pests or germs will easily develop resistance, which will increase the amount of pesticides used, resulting in adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy, and the field of action is relatively single
