Abstract

The invention relates to a germicide composition in combination with bupirimate, comprising bupirimate and partial methacrylic acid ester antiseptic mixing pairwise as effective components, wherein, the weight ratio of bupirimate to methacrylic acid ester antiseptic us 90:1-1:90, preferred 60:3-3:60. The total weight content of the effective components in the germicide composition is 1-90 %, preferred 5-75 %, and the balance consists of allowed and acceptable auxiliary elements in pesticides. The germicide composition can be prepared into wettable powder, suspending agent, soluble liquid formulation, missible oil, emulsion in water, and water dispersible granule with known methods. The germicide composition is mainly used for controlling fungal and bacterial diseases of vegetable, fruit tree, corn and other crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing pyrithrimol sulfonate and several methoxyacrylate compounds. Background technique [0002] Pyrimolsulfonate belongs to pyrimidine systemic fungicides and has protective and therapeutic effects. It can be quickly absorbed by plant roots, stems, and leaves, and circulates to various parts of the plant body, so it is resistant to rain erosion. It has the advantages of less dosage, high efficiency, low toxicity, and special effects on powdery mildew, so it replaces pyrimethol and pyrimol and other pesticides. Suitable for fruit trees, vegetables, flowers and other ornamental plants and field crops. Targets of prevention and control Various powdery mildews, such as apples, grapes, cucumbers, strawberries, roses, sweet raisin powdery mildew, have phytotoxicity to certain varieties of strawberries, apples, roses, etc. Its chemical s...
