Problems solved by technology

Especially the botrytis cinerea that has developed resistance to benzimidazole and carbamate fungicides has a better effect. However, when pyrimethanil is used on some crops such as eggplant, it is prone to phytotoxicity. When the concentration is high or the dosage is large, Drug damage will be more serious

Abstract

The invention relates to a composition for preventing and curing Botrytis cinerea. The dosage of the composition is a suspoemulsion; the active ingredients of the bactericide are cnidium lactone and pyrimethanil; the auxiliaries are alkylaryl polyoxyethylene ether, silkworm excrement, silicone and hydroxyethyl cellulose. The composition for preventing and curing the Botrytis cinerea, provided by the invention, has a very good preventing and curing effect on Peronospora schleidenii; through the adoption of preventing and curing effects of the cnidium lactone and the pyrimethanil on the Peronospora schleidenii, the composition for preventing and curing the Botrytis cinerea, provided by the invention, has the advantages of quick effectiveness, long lasting period and no influence on non-target crops.

Description

technical field [0001] The invention relates to a composition for preventing and treating gray mold, in particular to a composition for preventing and treating garlic gray mold, and belongs to the technical field of pesticides. Background technique [0002] Pyrimethanil, also known as Shijiale, has a chemical name of N-(4,6-dimethylpyrimidin-2-yl)aniline, a new type of anilinopyrimidine fungicide, which prevents the invasion of bacteria by inhibiting the production of bacteria-infecting enzymes Infect and kill germs. It has systemic conduction and fumigation effects, and after application, it quickly reaches the parts of the plant that cannot be reached by spraying, such as flowers and young fruits, to kill germs, and the drug effect is faster and more stable. Especially the botrytis cinerea that has developed resistance to benzimidazole and carbamate fungicides has a better effect. However, when pyrimethanil is used on some crops such as eggplant, it is prone to phytotoxic...
