Abstract

The invention discloses a streptomyces corchorusii strain NF0919, which is collected in China General Microbiological Culture Collection Center, and has the collection number CGMCC No. 3968. The strain can be used for preventing and treating rhizoctonia cerealis, rice false smut, rice sheath blight disease and other various plant diseases.

Description

field of invention [0001] The present invention relates to a kind of microorganism and application, relate more specifically to a kind of Streptomyces jute NF0919 bacterial strain, application and the preparation method of active fermented liquid thereof, belong to biological pesticide technology field, Background technique [0002] Rice sheath blight caused by the phytopathogenic fungus Rhizoctonia solani, Wheat sheath blight caused by Rhizoctonia cerealis and Chlorosclerotin oryzae Rice false smut (Rice false smut) caused by Ustilaginoidea oryzae is currently the main disease that damages rice. The above-mentioned three types of diseases can cause 10% to 30% yield loss all the year round, and in high-incidence years, the yield can be reduced by 80%, or even no harvest. At present, the prevention and control of such diseases mainly rely on chemical agents, but with the increasingly prominent problems of environmental protection and bacterial resistance, chemical control is...
