Embodiment

[0029] Example: Combined toxicity test of different ratios of tetramycin and pyraclostrobin.

[0030] 1.1 Test target

[0031] It was collected and isolated from potted cucumbers of the same type that had never been treated with tetramycin and pyraclostrobin in Shouguang, Shandong Province. The cucumber variety used for testing was Changchun Mici.

[0032] 1.2 Test method

[0033] The susceptible cucumber variety Changchun Mici was cultivated in a seedling pot and placed in a greenhouse for cultivation. After the plants reached the three-to-four-leaf stage, the leaves of the same leaf age were collected for the cultivation and determination of cucumber powdery mildew.

[0034] 1.2.1 Cucumber powdery mildew bacteria cultivation and preparation of spore suspension

[0035]Cucumber powdery mildew was cultured by live plant method at 20°C and 12 hours of alternating light and dark conditions, and subcultured once every 30 days. When inoculating, the conidia on the diseased ...

Abstract

The invention discloses a bactericidal composition containing tetramycin and pyraclostrobin. The effective components of the pesticide composition are tetramycin and pyraclostrobin in binary compounding, and the rest components are auxiliary components, wherein the mass ratio of tetramycin to pyraclostrobin in the pesticide composition is (1-50):(50-1); tetramycin and pyraclostrobin as the effective components in the preparation account for 1-80% by mass, and the auxiliary components allowable and acceptable to pesticide account for the rest. The dosage forms of the pesticide composition disclosed by the invention include emulsifiable concentrate, suspending agent, wettable powder, water dispersible granules, emulsion in water and microemulsion. The pesticide composition realizes a specific effect on fungal diseases such as powdery mildew of cucumber, downy mildew, fruit tree rot and alternaria leaf spot, rice blast, soybean root rot, cucurbits fusarium wilt, cotton verticillium wilt, jujube rust, grape white rot, panax pseudoginseng black spot, tea blister blight, wood rot, canker, gummosis, leaf cast, damping off in seedling stage and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition containing tetramycin and pyraclostrobin. 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] Pyraclostrobin (pyraclostrobin) is the latest methoxyacrylate fungicide from BASF. Pyraclostrobin is a new broad-spectrum fungicide. Mechanism of action: It is an inhibitor of mitochondrial respiration. That is, by preventing electron transfer in the synthe...
