Embodiment 1

[0015] Embodiment 1 kasugamycin and polyoxin complex pair to indoor virulence determination of Botrytis cinerea

[0016] Test object: Botrytis cinerea, collected in the field, isolated and purified on PDA medium in the room, and stored.

[0017] Test method: mycelial growth rate method. Under sterile conditions, use a hole puncher with a diameter of 5 mm to punch the bacteria cake at the edge of the colony of Botrytis cinerea for 3 days in pre-cultivation, and inoculate it on a PDA plate containing a series of concentrations of the test agent and drug-free, and repeat 3 times for each treatment. The second time, cultivate in the dark in the incubator at 25°C, measure the colony diameter (mm) of each treatment by the cross method after 3 days, calculate the inhibition rate, and use DPS to obtain the effective inhibitory concentration (EC 50 value).

[0018] CTC calculation method: Calculate the co-toxicity coefficient (CTC) according to Sun Yunpei's method. When CTC120, the ...

Abstract

The invention belongs to the field of pesticides, in particular to a pesticide composition containing kasugamycin and polyoxamycin, the weight ratio of kasugamycin and polyoxamycin is 1:25-25:1, which can be used for the prevention and treatment of crop diseases , especially for the control of tomato leaf mold and tomato gray mold, with obvious synergistic effect.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide composition containing kasugamycin and polyoxamycin. Background technique [0002] Kasugamycin is an antibiotic fungicide, which has protection, treatment and strong systemic activity, strong permeability, can move in the plant body, and has remarkable therapeutic effect. Kasugamycin can control various bacterial and fungal diseases on vegetables, fruits and rice crops, such as rice blast, tomato leaf mold, powdery mildew, cucumber bacterial angular spot, cabbage black rot, fruit and vegetable anthracnose Ideal medicine for diseases, etc. [0003] Polyoxin is a nucleoside antibiotic isolated from the cocoa streptomycin Asuo variant. In my country, it is a metabolite of Streptomyces aureus. Polyoxin consists of 14 different species from A to N. The mixture composed of homologues, the main active ingredient is polyoxin B, which belongs to the polyoxyimidine nucleoside agricul...
