[0016] Bioassay example 1: Toxicity determination of Zhongshengmycin and copper calcium sulfate compound against cucumber downy mildew

[0017] Test object: Cucumber downy mildew

[0018] (The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press), and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006" This test adopts the potted method of cucumber downy mildew. In On the basis of the preliminary test, select 2 melon seedlings at the true leaf stage with the same growth, write the label number with an oil-based marker, insert them into the pot of cucumber seedlings, and discharge them in sequence. Use the foliar spray method to spray the melon seedlings. On the leaves, after spraying treatment, dry the test materials in a fume hood or greenhouse for 24 hours and inoculate them. Cultivate in the greenhouse for 7 days to investigate the control effect, calculate the control effect with the disease ind...

[0023] Bioassay example 2: Toxicity determination of Zhongshengmycin and copper calcium sulfate complex against citrus canker

[0024] Subject: Citrus canker

[0025] The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press) and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006". In this test, the zone of inhibition method was used. On a sterile operating table, pour the NA medium into 90mm diameter Petri dishes, 20mL per dish, and then take 0.1mL of X. citri bacteria suspension and spread it evenly on the NA plate with a coating stick. After drying, punch a hole in the center of the plate with a hole puncher with a diameter of 7 mm, and then take 100 μL of the drug solution into the small hole. Each concentration was replicated five times. The treatment of adding sterile water to the small well was used as the blank control. After treatment, place them in a constant temperature sterile incubat...

Abstract

The invention relates to a bactericidal composition, the active ingredients of which are Zhongshengmycin and calcium copper sulfate; the mass proportion of the Zhongshengmycin and the calcium copper sulfate is 10:1-1:50, and the better proportion thereof is 5:1-1:20. After the Zhongshengmycin and the calcium copper sulfate are compounded, the bactericidal composition has obvious synergistic action and is used for the control of diseases in crops such as fruit trees, cotton, rice, vegetables and the like, especially bacterial diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing Zhongshengmycin. Background technique [0002] In recent years, due to single and unscientific drug use, many diseases have become resistant to the currently used pesticides, such as cucumber downy mildew and citrus canker, which have become a major problem in chemical control. At the same time, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Zhongshengmycin is an N-glycoside antibiotic with a broad antibacterial spectrum and is effective against a variety of bacteria and fungi. It has a good effect on Gram-negative and positive bacteria; it can cause protoplasm condensation in mycelium cells against fungi, and has a strong inhibitor...
