Embodiment

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

[0031] 1.1 Test target

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

[0033] 1.2 Test method

[0034] 15% tetramycin parent drug and 15% kasugamycin 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 kasugamycin parent drug with sterile water first to make 1000mg / L mother solution, and then dilute with sterile water when used. (Unit: mg / L)

[0035] The mixed use of tetramycin and kasugamycin is used to set 5 groups of proportioning ratios. On t...

Abstract

The invention relates to a bactericidal composition containing tetramycin and kasugamycin. The bactericidal composition is characterized by taking tetramycin and kasugamycin as active ingredients forbinary compounding, the mass ratio of the tetramycin to the kasugamycin as the active ingredients in the pesticide composition is (1-50):(50-1), the total mass percentage content of the tetramycin andthe kasugamycin as the active ingredients in the preparation accounts for 1-80 percent, and the rest is auxiliary ingredients allowed to be used and accepted in pesticides. Dosage forms of the pesticide composition are an emulsifiable concentrate, a suspending agent, wettable powder, water dispersible granules, an emulsion in water, a micro-emulsion, granules and microcapsules. The bactericidal composition is mainly used for controlling fruit tree rot diseases, Alternaria mali Roberts, rice blast, soybean root rot diseases, cucurbits fusarium wilt, cotton verticillium wilt, jujube rust diseases, grape white rot diseases, ginseng and pseudo-ginseng black spot disease, tea cake diseases, forest rot, canker diseases, leeding diseases, deciduous leaf diseases, forest seedling stage damping-off, erwinia aroideae, pseudomonas lachrymans, xanthomonas oryzae, physalospora piricola, fusarium graminearum and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing tetramycin and kasugamycin. 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, rice blast, soybean root rot, melon wilt, cotton verticillium wilt, jujube rust, grape white rot, ginseng panax notoginseng black spot, tea tea cake disease, forest rot It has special effects on fungal diseases such as disease, canker, gummosis, defoliation, and blight of forest seedlings. [0003] Kasugamycin is a biological fungicide produced by Actinomyces aureus successfully developed by the Institute of Microbiology, Chinese Academy of Sciences. It has strong systemic properties, preventi...
