Composition containing zinc thiazole and xinjunan acetate, preparations and application thereof

Abstract

The invention discloses a composition containing zinc thiazole and xinjunan acetate, preparations and application thereof. The effective component of the bactericidal composition is compounded by zinc thiazole and xinjunan acetate, and the rest are auxiliary components, wherein the sum of the mass fraction of zinc thiazole and xinjunan acetate in the effective component of the bactericidal composition is 2%-90%. The dosage forms of the pesticide composition include suspending agents, wettable powder, water dispersible granules, and granules, etc., and the composition is mainly used for prevention and control of apple tree canker, pepper virus disease, citrus canker, tomato virus disease, bacterial canker of tomato, soft rot of Chinese cabbage, cotton blight and verticillium wilt, bacterial leaf streak, Erwinia chyrsanthemi, and rice bacterial leaf blight, etc. Mixing of zinc thiazole and xinjunan acetate can improve the control effect and expand the control spectrum, at the same time the medication frequency can be reduced, and the medication cost is lowered, thus reaching the effects of prevention first and comprehensive control.

Description

technical field

[0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing thiazole zinc and octocalid acetate, as well as its preparation and application. Background technique

[0002] Zinc thiazole, chemical name: 2-amino-5-mercapto-1,3,4-zinc thiadiazole, molecular formula: C 4 h 4 N 6 S 4 Zn, CAS accession number: 3234-62-6. Zinc thiazole is a compound successfully developed by the applicant in 1999 (patent number: ZL00132119.6). It is a high-quality organozinc fungicide and has been widely used in the field of agriculture. Zinc thiazole has bactericidal properties (WO2008 / 151513), and has an outstanding control effect on plant bacterial diseases, and also has good control effects on some fungal diseases. At the same time, we found that proper concentration of thiazole zinc can promote the growth of plant roots and stems and leaves, and improve its stress resistance and disease resistance. In addition, thiazol...
