Abstract

The invention discloses a mildew proof and insect prevention sterilizing agent for a bamboo wood vine willow herb. The mildew proof and insect prevention sterilizing agent for the bamboo wood vine willow herb is prepared from the components in percentage by weight: 15%-25% of methylene dithiocyanate, 25%-30% of carbendazim, 20%-30% of chlorothalonil and 20%-30% of sodium fluosilicate, the mildew proof and insect prevention sterilizing agent for the bamboo wood vine willow herb is prepared from the components in percentage by mass: 20% of methylene dithiocyanate, 30% of carbendazim, 25% of chlorothalonil and 25% of sodium fluosilicate, the carbendazim is prepared from the raw materials: a single cyanamide water solution, methyl chloroformate, sodium hydroxide, o-phenylenediamine and concentrated hydrochloric acid, the carbendazim with a high specification is prepared, and a preparation method of the chlorothalonil comprises the step that metric isophthalonitrile is put into a vaporizerfor vaporization. The sterilizing agent is prepared by adopting the raw materials of high-purity methylene dithiocyanate, carbendazim, chlorothalonil and sodium fluosilicate, the mildew proof and insect prevention high efficiency can be better ensured, the long-time mildew proof can be ensured, pests are killed thoroughly, so that the using effect of the mildew proof and insect prevention sterilizing agent for the bamboo wood vine willow herb is better ensured, and the efficiency of the mildew proof and insect prevention sterilizing agent for the bamboo wood vine willow herb is better ensured.

Description

technical field [0001] The invention relates to the technical field of fungicides, in particular to a mildew-proof, insect-proof and fungicide for bamboo, wood, rattan, willow, and grass. Background technique [0002] Fungicides are a class of pesticides used to prevent and control plant diseases caused by various pathogenic microorganisms, generally referring to fungicides. However, internationally, it is usually used as a general term for agents to prevent and control various pathogenic microorganisms. The use of fungicides is an economical and effective method to prevent and control plant diseases. There are many anti-mold and insect repellents for bamboo and wood in the market, but most of them have single formula, poor protection, not long enough for anti-mold, and incomplete insecticide. The main reason is that when the product is processed, the efficacy of the drug is single, and the mold and bacteria cannot be fully controlled. It is easy to cause the mold and bacte...
