Abstract

The invention discloses a bactericidal composition containing prothioconazole and prochloraz. The bactericidal composition comprises active ingredients, namely prothioconazole and prochloraz which are compounded and the balance being auxiliary ingredients, wherein a mass ratio of prothioconazole to prochloraz in the pesticide composition is (1-50):(50-1); the mass part ratio of the active ingredients, namely prothioconazole and prochloraz, in the preparation is 1-80 percent, and auxiliary ingredients are pesticidally permitted and acceptable. The bactericidal composition has the dosage forms such as missible oil, suspending agent, wettable powder, water dispersible granules, emulsion in water, microemulsion, granules, microcapsules and soluble concentrate and is mainly used for preventing and treating powdery mildew, banded sclerotial blight, wilt, leaf spot disease, rust disease, stalk break and rice blast of cereal crops as well as anthracnose and leaf spot disease of melons, fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing prothioconazole and prochloraz. Background technique [0002] Prothioconazole is a new broad-spectrum triazolethione fungicide developed by Bayer. Its chemical name is (RS)-2-(2-(1-chlorocyclopropyl)-3-(2-chlorocyclopropyl) Phenyl)-2-hydroxypropyl-1-2-dihydro-3-1,2,4-triazole-3-thione, prothioconazole has low toxicity, no teratogenic, mutagenic, harmful to embryos Non-toxic, safe for people and the environment. Prothioconazole is mainly used to prevent and control many diseases of cereal crops such as wheat, barley, rape, peanut, rice and bean crops. It is very good for almost all wheat diseases. Effects, such as wheat and barley powdery mildew, sheath blight, fusarium wilt, leaf spot, rust, sclerotinia, net spot, moire, etc. It can also control soil-borne diseases of oilseed raisins and peanuts, such as fungus Sclerotinia, an...
