Description

technical field

[0001] The invention relates to the field of development and utilization of microbial germplasm resources, and specifically relates to a bacillus subtilis for preventing and treating crop fusarium diseases and its application. Background technique

[0002] Fusarium (Fusarium) belongs to the fungus of the subphylum Deuteromycotina, which is a kind of fungus distributed worldwide. It can not only survive winter and summer in the soil, but also infect a variety of plants (food crops, economic crops, medicinal plants and Ornamental plants), causing ear rot, root rot, stem rot, stem base rot, flower rot and other diseases of plants, with more than 100 species of host plants, infecting the vascular system of host plants and destroying the vascular bundles of plant transport tissues , and produce toxins in the process of growth, development and metabolism to harm crops, cause crop wilting and death, and affect yield and quality. Among them, the diseases caused by F...
