Abstract
The invention belongs to the technical field of pesticide, specifically relates to an agricultural germicide containing thiabendazole and 1%-80% of effective ingredients. The thiabendazole which is a triazole germicide developed by Isagro Ricerca, is a sterol demethylation inhibitor, capable of being absorbed by plants rapidly and conducted inside due to its good systematic ability, with good protection and treating activities, for the control of wheat powdery mildew, loose smut, rust disease, stinking smut, glume blight, barley leaf blotch, banded sclerotial, sphacelotheca reiliana, sphacelothecareliana, powdery mildew of melon and fruit, leaf spot of banana, altemaria mali, pear scab and grape powdery mildew.
Description
Technical field:
The invention belongs to technical field of pesticide, announced a kind of disinfectant use in agriculture that contains tetraconazole, belong to triazole bactericidal agent.
Background technology
In recent years, country is to an organic solvent restriction increasingly stringent in the pesticidal preparations, and wetting powder and pulvis can bring dust pollution, thereby promote agricultural chemicals to develop along the direction of efficient, low toxicity, safe and reasonable and Environmental compatibility, people are when strengthening the novel pesticide research and development, pay attention to research and development more to the formulations of pesticide, it wherein is the direction that the pesticides new formulation of matrix has become world's formulations of pesticide research and development with water, and as a kind of novel aqueous chemical pesticidal preparations, formally a kind of like this environment friendly agricultural preparation of microemulsion.
The tetraconazole English name is tetraconazole, and chemical name is (RS)-2-(2,4 dichloro benzene base)-3-(1H-1,2,4-triazol-1-yl) propyl group 1,1,2,2-tetrafluoro ethyl ether.
Structural formula is:
Tetraconazole is that tetraconazole is a sterol demethylation inhibitor by the triazole bactericidal agent of Italian Yi Saige company research and development. because absorption in having well, therefore can be promptly by plant absorbing, and in conducted inside; Have good protection and therapeutic activity. 6 weeks of lasting period. this medicine is used for cereal crop such as wheat, barley, oat, rye etc., fruit tree such as banana, grape, pears, tsaoko etc., vegetables such as melon, beet, the control of ornamental plants etc.
