Sterilizing composite for controlling pyricularia oryzae

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a sterilizing composite containing tetramycin and prochloraz and application of the sterilizing composite in the aspect of controlling pyricularia oryzae. The sterilizing composite has the advantages that since the tetramycin and the prochloraz are adopted for compounding, the purpose of synergy is achieved, the controlling effect on the pyricularia oryzae is further improved, the used amount of drugs is reduced, the pesticide residue is reduced, and simultaneously the sterilizing composite plays a better role in delaying the drug resistance of pathogenic bacteria.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to the application of a bactericidal composition compounded with Wuningmycin and prochloraz to prevent and treat rice blast. Background technique [0002] Wuningmycin, also known as tetramycin and 11371 antibiotic, is derived from an actinomycete strain isolated and screened from soil samples in Wuzhou, Guangxi, Streptomyces ahygroscopicn wuzhouensisn subsp., belonging to actinomycetes, Streptomyces. Metabolites produced during fungal growth are generally produced by engineered fermentation. This product has a wide bactericidal spectrum, and has a strong killing effect on 26 known pathogenic fungi of the three major categories of flagella, ascomycetes and deuteromycotina fungi. It is suitable for the prevention and control of various fungal diseases of various crops. Especially for fruit tree rot, spot defoliation, cotton yellow wilt, soybean root rot, rice blast, ...

AI Technical Summary

Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the generation of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a large increase in dosage, shortened spraying cycle, and poor use effect, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products also increase, which affects the health and normal survival of humans and animals. The compound use of Wuningmycin and prochloraz is used to prevent rice blast , has not been reported at home and abroad
