Bactericide composition for preventing and treating wheat scab

Abstract

The invention discloses a bactericide composition for preventing and treating wheat scab and belongs to the technical field of chemical prevention and control on diseases. Effective components of the bactericide composition comprise a component A which is prochloraz-manganese chloride complex and a component B which is thiram, wherein the weight ratio of the component A to the component B is 1:50-50:1; the bactericide composition also comprises auxiliaries and a carrier besides the effective components; the effective components A and B account for 15-80 percent of the total weight of the bactericide; the auxiliaries account for 20-80 percent of the total weight of the bactericide; the carrier accounts for the rest of the total weight of the bactericide. The bactericide composition can be prepared into wettable powder and the like. The composite bactericide disclosed by the invention has a good preventing and treating effect on the wheat scab and the like. Compared with a conventional preventing and treating medicine, the bactericide composition has the advantages that the using amount of the bactericide composition can be reduced, the environment pollution and residues of agricultural products are reduced, and the drug resistance of a single bactericide can be delayed. Compared with a single dosage, the bactericide composition has the advantage that the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical prevention and control, and relates to a fungicide composition for preventing and treating wheat scab. Background technique [0002] Wheat head blight (also known as wheat ear dry, rotten wheat head, red wheat head), is one of the main diseases of wheat. Wheat head blight occurs widely in the world, mainly in humid and semi-humid regions, especially in temperate regions with humid and rainy climates. It can be damaged from seedlings to heading, mainly causing seedling rot, stem base rot, stalk rot and ear rot, among which the most serious damage is ear rot. Wheat scab not only causes serious yield loss and quality impact to wheat production, but more importantly, its myelotoxin affects food safety, which has attracted much attention. Fusarium head blight is caused by the fungus of the genus Fusarium. While causing losses to the yield of wheat, it also produces mycotoxins mainly deoxynivalenol ...

Problems solved by technology

Thiram is a dithiocarbamic acid fungicide, which is characterized by low cost, wide bactericidal spectrum, and multiple action sites. The bacteria are not easy to develop drug resistance, but the control effect is not very satisfactory.
