Embodiment

[0030] Example: Combined toxicity test of different ratios of tetramycin and Zhongshengmycin.

[0031] 1.1 Test target

[0032] Bacterial angular spot of cucumber (the bacteria strain was collected from the cucumber greenhouse in Yifeng Town, Jimo City, Qingdao City, Shandong Province, and was isolated and purified by the Biotest Laboratory of the R&D Center of Hailier Pharmaceutical Group Co., Ltd.).

[0033] 1.2 Test method

[0034] 15% tetramycin parent drug and 15% Zhongshengmycin parent drug were provided by Shandong Hailier Chemical Co., Ltd. Add sterilized water to the purified slant test tube bacteria to make the original bacteria suspension, and then dilute it to 107 / liter bacteria suspension for later use. Dissolve tetramycin and Zhongshengmycin parent drug in sterile water first to make 1000mg / L mother solution, and then dilute with sterile water when used. (Unit: mg / L)

[0035] The mixture of tetramycin and Zhongshengmycin was used to set 5 groups of propor...

Abstract

The invention provides a bactericidal composition containing tetramycin and zhongshengmycin. The bactericidal composition comprises compounded effective components consisting of tetramycin and zhongshengmycin, with the balance being auxiliary components. The mass ratio of tetramycin to zhongshengmycin in the composition is 1-50 50-1, and the mass fraction of tetramycin and zhongshengmycin in a preparation is 1 to 80%, with the balance being auxiliary components which are allowed to use and admitted in pesticides; dosage forms of the composition comprise missible oil, a suspending agent, a wettable powder, a water dispersible granule, an emulsion in water, a micro-emulsion, a granule and a micro capsule. The composition is mainly used for preventing and treating rot diseases of fruit trees, alternaria leaf spot, rice blast, soybean root rot, fusarium wilt of cucurbits, cotton verticillium wilt, rust diseases of jujube trees, white rot of grape, black spot of ginseng and pseudo-ginseng, Exobasidium vexans Massee of tea, forest rot, canker, gumming diseases, leaf cast, damping off of forest seedlings, soft rot bacteria of vegetable, Pseudomonas lachrymans, Xanthomonas oryzae pv. oryzae, Physalospora piricola, Fusarium graminearum, etc.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing tetramycin and Zhongshengmycin. Background technique [0002] Tetramycin (Wuningmycin) is a fermentation metabolite of Streptomyces nonhygroscopicus subsp. Fungi have a strong killing effect. It is suitable for the prevention and control of various fungal and bacterial diseases of various crops. Especially for fruit tree rot spot leaf spot disease; rice blast; soybean root rot; melon wilt; cotton verticillium wilt; jujube rust; grape white rot; It has special effects on fungal diseases such as disease, canker, gummosis, defoliation, and blight of forest seedlings. [0003] Zhongshengmycin is a new type of agricultural antibiotic successfully developed by the Institute of Biocontrol of the Chinese Academy of Agricultural Sciences. It is an antibiotic produced by the Hainan variety of Streptomyces lavender. It is an N-glycoside...
