Embodiment

[0019] For the strain characteristics of the Streptomyces jute NF0919 strain provided in the present invention, see patent ZL201010236886.1. The extraction method of product in Streptomyces jute NF0919 strain fermented liquid of the present invention comprises the following steps:

[0020] (A) Activation of the strain and cultivation of primary seed culture medium

[0021] The slant of the preserved NF0919 strain was activated on Gao’s No. 1 medium, cultured at 30°C for 10 days, and 1 cm 2 Inoculate 50 mL of primary seed culture solution (50 mL of culture solution in a 250 mL Erlenmeyer bottle) with a large or small bacterial block, place on a shaker at 170 rpm at 30°C for 44-48 h, and the 50 mL of primary seed culture The composition of the liquid is: 3% soluble starch, 2% glucose, 1% yeast powder, 1% peptone, 0.5% NaCl, K 2 HPO 4 0.2%, soluble starch, glucose, yeast powder, peptone, NaCl and K 2 HPO 4 The unit ratio of content is W / V;

[0022] (B) Cultivation of se...

Abstract

The invention relates to a method for extraction of an active metabolite from a Streptomyces corchorusii NF0919 strain (with a preservation number of CGMCC No.3968 in CGMCC and a strain patent number of ZL201010236886.1) fermentation broth. The metabolite can effectively prevent and treat Venturia nashicola (also known as pear scab) caused by plant pathogenic fungus Venturia piritna infection and Physalospora piricola Nose (also known as Pear perennial canker and Internal bark necrosis) caused by Physalospora piricola infection.

Description

field of invention [0001] The present invention relates to a kind of microorganism and application, more specifically relate to a kind of Streptomyces jute ( Streptomyces corchorusii ) NF0919 strain metabolites and their application in the prevention and treatment of pear tree diseases belong to the technical field of biological pesticides. Background technique [0002] by the phytopathogenic fungus Scabella pears ( Venturia piritna ) infection caused by pear scab (also known as pear scab) and Phomopsis rotifera ( Physalospora piricola ) infection caused by pear ring spot (also known as pear tumor skin disease, rough skin disease), is the main fungal disease on pear trees. The prevention and control of pear diseases is currently mainly through chemical control, and the following chemical agents are commonly used for control: lime sulfur, diniconazole, chlorothalonil, thiophanate-methyl, myclobutanil, mancozeb, tuzet, Senammonium, azoxystrobin, kresoxim-methyl, difenocon...
