Problems solved by technology

[0009] The use of the above-mentioned single agent, as well as the defects of the dosage form itself, can easily cause the bacteria to develop drug resistance. It is necessary to increase the amount of drug or the frequency of application, which is costly and increases the difficulty of subsequent sterilization. In addition, the problem of pesticide residues and environmental pollution is will create a vicious circle
The development of environmentally friendly and efficient pesticide products will become a future trend, and there is no report on the suspoemulsion of pyrithrimol-boscalid

Abstract

The invention discloses a bupirimate.boscalid suspoemulsion and a preparation method thereof. The bupirimate.boscalid suspoemulsion is prepared from the following components in percentage by weight according to a formula: 5-20 percent of bupirimate and 5-20 percent of boscalid. According to the bupirimate.boscalid suspoemulsion and the preparation method disclosed by the invention, by compounding the bupirimate and the boscalid and adopting a reagent form of suspoemulsion, the two active ingredients have synergistic interaction, so that the sterilization treatment spectrum action is enlarged, the effect of controlling germs is remarkably improved, the drug resistance problem of the germs is relieved, the therapeutic effect on diseases including powdery mildew, botrytis cinerea, sclerotinia and various rot diseases of crops including rapes, grapes, fruit trees, vegetables and field crops is good, the dosage form is environmentally friendly, and pollution and damage to the environment are reduced.

Description

technical field [0001] The invention belongs to a new dosage form of a pesticide bactericidal composition, in particular to a pyrithrimol sulfonate boscalid suspoemulsion and a preparation method thereof. Background technique [0002] Ethyrimolsulfonate English common name: bupirimate, chemical name: 5-butyl-2-ethylamino-6-methylpyrimidin-4-yl dimethylaminosulfate [0003] [0004] The appearance of pyrithrimol sulfonate technical product is light brown waxy solid with a melting point of 50-51°C. It is easily hydrolyzed in dilute acid and unstable in long-term storage above 37°C. The solubility in water at room temperature is 22mg / L, soluble in most organic solvents, insoluble in alkanes. [0005] Pyrimolsulfonate is a systemic fungicide, which is mainly used to prevent and control powdery mildew in crops such as apples, greenhouse roses and strawberries. [0006] Boscalid Chinese alias: Kaizer, chemical name: 2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide, its struct...
