Abstract

The invention discloses application of tioconazole in preparation of a bactericide for preventing and controlling phytopathogenic fungi and bacteria. Through indoor agent sensitivity determination, itproves that the tioconazole has good inhibitory activity on main diseases of important grain crops including fusarium graminearum causing wheat scab, maize curvularia causing maize leaf spot, rhizoctonia cerealis causing sheath blight and magnaporthe grisea causing rice blast; moreover, the tioconazole has good inhibition activity on botrytis cinerea of gray mold causing main diseases of fruits and vegetables, Physalospora piricola Nose causing ring rot of apples and alternaria tenuissima causing leaf spot of the fruits and vegetables; and moreover, the tioconazole also has good inhibitory activity on soil-borne diseases which are extremely difficult to control in agricultural production, such as fusarium oxysporum causing fusarium wilt, and the antibacterial activity of the tioconazole is even better than that of carbendazim and tebuconazole which are traditional bactericides. The invention provides application of the tioconazole in prevention and control of important plant diseasesin agricultural production for the first time, and the tioconazole has wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to the application of tioconazole in the preparation of fungicides for preventing and treating plant pathogenic bacteria. Background technique [0002] The Food and Agriculture Organization of the United Nations (FAO) estimates that the loss of crop production in the world is about 40% (440-550 billion yuan) due to damage from diseases, insect pests and weeds, and the impact on trees is even more difficult to estimate. The losses recovered through the work of scientists and various technology extension personnel engaged in pest research all over the world reached 300-400 billion yuan. For a long time, chemical control has been the main means of controlling plant diseases. The long-term use of large quantities of chemical pesticides not only leads to resistance problems, but also causes pesticide residues, kills non-target organisms, pollutes the ecological envi...
