Biopesticide complex inoculant for root disease prevention and control of crops like cotton and preparation method thereof

Abstract

The invention discloses a biopesticide complex inoculant for root disease prevention and control of crops like cotton and a preparation method thereof. The biopesticide complex inoculant is microbial pesticide utilizing a powerful microbial combination and having efficient effect on root diseases of the crops like cotton. Specifically, microorganisms like white hook streptomyces generating gentamicin, streptomyces ambofaciens generating spiramycin and Congomycin, streptomyces cellulosae generating streptomycin and actinomycin, streptomyces hygroscopicus Jingang variant generating Jingangmycin and preventing and controlling rice sheath blight, streptomyces microaureus generating kasugamycin and preventing and controlling rice blast, streptomyces generating staphylomycin and anti-G+cell, streptomyces Jingyangensis generating long-acting stimulin and streptomyces rimosus generating tetraenes antibiotics are subjected to fermenting cultivation, and an improved culture medium formula is adopted to prepare 2 billion per ml biological unit. The biopesticide complex inoculant is used for seed soaking, seed mixing or being blended in biological seed fertilizer before seeding the crops like cotton to play a role in preventing and controlling root diseases of the crops like cotton, and can be used for root irrigation when cotton and other crops are infected by the diseases to prevent and control crop root diseases, and effective rate reaches 65-90%.

Description

technical field [0001] The invention relates to a microbial pesticide, in particular to a biological pesticide compound microbial agent for preventing and controlling root diseases of crops such as cotton and a preparation method thereof. Background technique [0002] Like other organisms, there are pathogenic bacteria and microbial systems beneficial to plants in the body, body surface, roots, stems and leaves. There are various relationships such as antagonism, parasitic and competition among different microorganisms. [0003] The prevention and control of plant diseases is to weaken or reduce the inoculation quantity and activity of pathogenic organisms, or to promote the growth and development of plants through direct or indirect one or more biological factors, so as to achieve the purpose of reducing diseases and improving the quantity and quality of products . Microorganisms involved in the biological control of plant diseases include fungi, bacteria and actinomycetes...
