Abstract

The invention is a streptomyces angustmyceticus ER1396 strain (having the preservation number of CGMCC No.9871 in CGMCC) and a method for preparing a soluble powder from a fermented liquid. The soluble powder can effectively prevent and control anthracnose caused by colletotrichum spp. fungus invasion.

Description

field of invention [0001] The invention relates to a microorganism and its application, more specifically to a Streptomyces angustmyceticus strain, application and preparation method thereof, belonging to the technical field of biological pesticides. Background technique [0002] Anthracnose caused by fungal infection of the genus Colletotrichum spp. is the main disease of strawberry seedlings and grape harvest in summer. At present, the prevention and treatment of anthracnose is mainly controlled by chemical agents. Commonly used fungicides include methoxyacrylate (QoI) fungicides (azoxystrobin, kresoxim-methyl), and sterol biosynthesis inhibitors (SBIs) fungicides. (difenoconazole, imidamide), succinate dehydrogenase inhibitor (SDHI) fungicides (boscalid, fluopyram, penthiopyrad, flufenapyramide) and inhibiting cell mitosis Benzimidazole (MBC) fungicides (carbendazim, benomyl, methylthiophanate) and so on. Due to the frequent and saturated application of chemical agents ...
