Problems solved by technology

In addition, although domestic pesticide manufacturers produce carbendazim and procymidone or mixed wettable powders of carbendazim and diethofencarb, these preparations cannot be sprayed with a fog machine, but can only be sprayed with a large amount of water.
Because spraying water mist increases the humidity in the greenhouse, which promotes the growth and development of germs, which is not conducive to disease control, so users are reluctant to use this type of preparation

Abstract

A bactericide in the form of smoking agent for preventing and treating the gray mold of vegetables is perpared from the carbendazim, diethofencarb, surfactant, diluent with high boiling point and antifreezing agent through proportionally mixing. It is applied by use of aerosol generator to spray it.

Description

Technical field [0001] The technical scheme of the present invention relates to a kind of biocide characterized by the thermal mist method, specifically for the control of botrytis cinerea of ​​vegetables in greenhouses, and the main drug active ingredient is benzimidazole-2-methyl carbamate ( Commonly known as carbendazim) and 3,4-diethoxyphenylcarbamate isopropyl ester (commonly known as diethofencarb) hot spray (commonly known as aerosol) type fungicide and its preparation method and use method. Background technique [0002] Although there are many documents on fungicide pesticides used to prevent and control vegetable gray mold, CN1091897A and CN1288663A also disclose the control vegetable gray mold containing a certain amount of carbendazim (i.e. benzimidazole-2-methyl carbamate). The compound fungicides used for disease, however, their use method is to use wettable powder or emulsifiable concentrate. The use of these formulations is large and the bactericidal efficien...
