Agricultural bactericide composition containing substituted benzene bactericide

Abstract

The present invention belongs to the field of agricultural chemical technology. The agricultural bactericide composition includes ethylicin 2-95%, substituted benzene bactericide 0.5-60%, assistant and filler in proper amount. Its substituted benzene bactericide is one of thiophanate-methyl, metalaxyl, oxadixyl and amidithion. The agricultural bactericide composition of the present invention may be used widely in preventing and controlling various diseases caused by fungi, bacteria and virus in grain crop, economic crop, forest, flower, vegetable etc.

Description

[0001] The present invention is a divisional application. The original title of the invention is "a compound broad-spectrum bactericidal pesticide", the application number is 96111880.6, and the filing date is August 27, 1996. Technical field [0002] The invention relates to an agricultural sterilization composition containing substituted benzene fungicides, and belongs to the technical field of pesticides. Background technique [0003] Existing bactericidal pesticides, such as "etiticin antibacterial agent", have an effective content (weight percentage) of more than 40-80%, which is highly corrosive and has serious pollution. The plants are damaged and can only be used for seed and soil treatment. Although the antibacterial spectrum of ethyl allicin is broad, it still has a poor control effect on diseases such as powdery mildew, rust, white spot, and virus diseases with high incidence. Shortcomings. Other fungicides and pesticides, such as organophosphorus fungicides: Dafenjing,...

AI Technical Summary

Problems solved by technology

[0003] Existing bactericidal pesticides, such as "ethyl allicin antibacterial agent", have an effective content (percentage by weight) of more than 40-80%, which is highly corrosive and seriously polluting, and is harmful to the body of the sprayer, to the seeds of plants or Plants are damaged, and can only be used for seed and soil treatment. Although acetoallicin has a wide spectrum of antibacterial agents, it still has poor control effects on diseases such as powdery mildew, rust, white spot, and viral diseases. Shortcomings

Other fungicides and pesticides, such as organophosphorus fungicides: Daobangjing, difenphos, etc.; such as organosulfur fungicides: captan, foltan, etc.; such as substituted benzene fungicides: thiophanate-methyl, Metalaxyl, Oxafaxyl, Seed Dressing Spirit, etc.; such as heterocyclic fungicides: triadimefon, propiconazole, riceblastyl, azinyl, etc.; such as antibiotic fungicides (including medical): blasticidin , chloramphenicol, etc., have the disadvantages of single bactericidal spectrum, easy to produce drug resistance, or slow healing of lesions

In a word, existing bactericidal pesticides, because there are the above-mentioned major defects, are not ideal in the promotion and application of agricultural production, and agricultural plant protection is in urgent need of a new type of bactericidal pesticides.
