Dry suspending agent containing bismerthiazol and fluazinam and preparation method thereof

Abstract

The invention relates to a dry suspending agent containing bismerthiazol and fluazinam. The dry suspending agent is prepared from the following components in percentage by weight: 10%-30% of bismerthiazol, 10%-20% of fluazinam, 6%-20% of a dispersant, 1%-10% of a wetting agent, 1%-12% of a disintegrating agent, 0.3%-3% of a suspending aid and the balance of a carrier. The invention further relates to a preparation method of the dry suspending agent containing bismerthiazol and fluazinam. The dry suspending agent containing bismerthiazol and fluazinam has the beneficial effects that the composition has a synergistic effect after being compounded and a prevention and treatment range is enlarged; the prevention and treatment on bacterial diseases is increased; the dry suspending agent has a better effect in fungal diseases of fruit trees or grain crops, and particularly has a remarkable effect on citrus scab, citrus canker, apple scab, rice bacterial leaf blight, rice blast and the like; and the drug resistance is not easy to generate and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a dry suspension containing euconazole and fluazinam and a preparation method thereof. Background technique [0002] Yebazole, also known as Yeqingshuang, is a long white columnar crystal or light yellow loose fine powder, which is a low-toxicity fungicide. Non-carcinogenic, teratogenic, mutagenic, efficient and safe systemic fungicide, with good preventive and therapeutic effects. It is mainly used to prevent and control plant bacterial diseases. It has a long-lasting effect and stable drug effect. It has good control effects on rice bacterial blight, bacterial streak disease and citrus canker. [0003] Fluazinam (Fluazinam) is a 2,6-dinitroaniline compound, which is a broad-spectrum protective fungicide against Alternaria, Botrytis, Phytophthora, Unipota, Sclerotinia and Scab bacteria are very effective. The specific diseases that fluazinam can control include cucumber pepper bli...

Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the emergence of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a significant increase in dosage, shortened spraying cycles, and poor use effects, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products have also increased, which affects the health and normal survival of humans and animals.
