Abstract

The invention relates to a compound bactericide containing propiconazole and a preparation method thereof, the compound bactericide containing the propiconazole is prepared from the following raw materials in parts by weight: the propiconazole, 1,2-bis (3-methoxyl carbon-2-thioureido) benzene, polyethylene glycol 200, sodium dodecyl benzene sulfonate, modified white carbon black, a high-carbon alcohol fatty acid ester compound, propylene glycol, sodium silicate and plant ash; the compound bactericide containing the propiconazole is prepared from compounding the propiconazole and the 1, 2-(3-methoxy carbon-2-thioureido) benzene which are complementary in drug effects and high in drug effect activity, and the compound bactericide containing the propiconazole can be directly applied to leaves, root and stems of crops, and has the characteristics of being high in adhesive force, lasting in sterilization effect and wide in sterilization range.

Description

technical field [0001] The invention belongs to the technical field of pesticide fungicides, and in particular relates to a compound fungicide containing propiconazole and a preparation method thereof. Background technique [0002] Propiconazole is one of the new broad-spectrum pesticide fungicides of triazoles. When it acts on plants, it can be quickly absorbed by plant roots, stems, and leaves, and has good therapeutic and preventive effects. Studies have shown that propiconazole has a good therapeutic effect on wheat take-all, powdery mildew, rust, root rot, rice bakanae, sheath blight, banana leaf spot and other diseases, and can effectively control most higher fungi disease. [0003] During the growth and development of most crops, especially wheat, peanuts, corn, etc., are vulnerable to fungal diseases. Due to the wide variety of fungal diseases, complex symptoms, and rapid spread, it is more difficult to control and seriously affect the yield and quality of crops. ...
