Embodiment 1

[0021] 1. Determination of indoor antibacterial activity

[0022] 1.1 Test time and place

[0023] From April to July 2012, it was carried out in the Modern Agriculture Research Laboratory of Zhenjiang Institute of Agricultural Sciences.

[0024] 1.2 Tested strains

[0025] Strawberry Fusarium wilt was collected from greenhouse strawberries in Jurong City, Jiangsu Province, and the variety was Red Cheek. It was isolated, identified, and verified according to Koch’s Rule by the Modern Agriculture Research Office of Zhenjiang Institute of Agricultural Sciences and preserved for future use. Strains were stored on potato sucrose agar (PSA) slant (4°C).

[0026] 1.3 Drugs to be tested

[0027] 100 billion CFU / gram of Bacillus subtilis DJ-6 (Bacillus subtili) parent drug, provided by the Modern Research Laboratory of Zhenjiang Institute of Agricultural Sciences; 97% pyraclostrobin (Pyraclostrobin) technical drug, provided by Jiangsu Yunnong Chemical Co., Ltd. .

Abstract

The invention discloses a biological compound bactericidal composition. The biological compound bactericidal composition contains two active ingredients, namely 5-40% pyraclostrobin and 4-200 billion CFU / g of bacillus subtilis. The invention also discloses application of the biological compound bactericidal composition in prevention and treatment of strawberry blight. The bacillus subtilis DJ-6 and the pyraclostrobin in the compound composition are bactericides different in mechanism of action; the biological compound bactericidal composition is good in prevention and treatment effects on continuous cropping strawberry diseases, obvious in growth promoting effect, environmentally friendly, low in cost and simple and easy to prepare, and further is capable of obviously reducing sick seedlings and dead seedlings, obviously improving the yield and the quality of continuous cropping strawberry and well meeting the requirements on crop disease prevention and treatment in production.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a biological compound bactericidal composition and its application. Background technique [0002] Strawberry (Fragaria ananassa Duch) is very popular for its soft and juicy fruit, delicious taste, rich nutrition, short growth period, early fruit and high yield, and has an important economic position in the international market. Strawberry wilt caused by root infection of Fusarium oxysporum f.sp.fragariae is the main soil-borne disease that harms strawberries. Continuous cropping of strawberries in greenhouses is very common, resulting in strawberry wilt The occurrence of the disease is more and more serious, and the incidence rate of the plants can reach 89.2%. Strawberry wilt mainly occurs in the high temperature period, and can occur at the seedling stage or flowering to harvest stage. In the initial stage, only the heart leaves turn yellow-green or yellow, and some of them ...
