Abstract

Compared with a single preparation, the broad-spectrum bactericidal low-toxicity low-residue growth-promoting Saisentong compound or composition have the advantages that when applied to crops, the invention can sterilize and supplement manganese and zinc at the same time; compared with compounding, the composition is accurate in preparation content, convenient to apply, easy to prepare, lower in energy consumption, more environmentally friendly, better in storage stability or prevention and treatment effect and the like, and tedious preparation processes are reduced; the invention is suitablefor preparing a composition containing the compound and pesticides for preventing and treating various bacterial and fungal diseases on crops and/or promoting the health or growth and development of the crops, or is applied to medicaments in the fields of protecting industrial materials from being invaded by germs and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular, it provides a new compound or compound of mancozeb, which is broad-spectrum bactericidal, low-toxic and low-residue, and promotes crop growth, as well as its composition and its preparation method and application. Background technique [0002] Ye Qingshuang, chemical name is N, N'-methylene-bis(2-amino-5-mercapto-1,3,4-thiadiazole), molecular formula C 5 h 6 N 6 S 4 , with a molecular weight of 278.34, is a systemic curative fungicide independently developed in my country. It has the characteristics of high efficiency, low toxicity, low residue, long-lasting effect, and strong systemic property. It is effective against rice bacterial blight and bacterial streak And citrus canker has good control effect, and it has been popularized and used in my country for nearly 40 years. The production technology of Ectilazole technical was once included in the "China Export Prohibited and...
