Abstract
The invention relates to a plant disease preventing and treating composition and also relates to a method for preventing and treating pathogenic bacteria of plants. The plant disease preventing and treating composition contains Orysastrobin represented by a formula I shown in the description and Tetraconazole, wherein the weight ratio of Orysastrobin to Tetraconazole is (1: 100) to (100: 1). Orysastrobin and Tetraconazole are subjected to binary compounding and act on the pathogenic bacteria and / or environment therefor, or the plants, plant parts, seeds, soil, areas, materials or spaces, so that the plant disease preventing and treating composition can be used for preventing and treating fungi and bacteria on cereals, beans, fruits, vegetables, cotton and ornamental plants and achieves the effect of synergism. The composition containing Orysastrobin and Tetraconazole can be used for treating seeds of plants needing protection.
Description
technical field [0001] The invention relates to a plant disease control composition, and also relates to a method for controlling plant pathogenic bacteria. Background technique [0002] Orysastrobin, chemical name: (2E)-2-(methoxyimino)-2-{2-[(3E,5E,6E)-S-(methoxyimino)-4,6 -Dimethyl-2,8-dioxa-3,7-diazanon-3,6-dien-1-yl]phenyl}-N-methylacetamide from WO-A 97 / 15552 is known as a fungicide, which is particularly effective against the rice blast pathogen and is mainly used in rice to control rice blast and sheath blight. The structural formula is shown in Formula I. [0003] [0004] (Formula I) [0005] Harmful fungi are controlled by applying orysastrobin by treating the seeds, spraying or dusting the plants or the soil before or after sowing of the plants or before or after emergence of the plants. [0006] Tetraconazole, chemical name: 2-(2,4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propyl 1,1,2, 2,-Tetrafluoroethyl ether, known as a fungicide from EP234242. The ...
