Abstract

The invention belongs to the field of agriculture, and relates to a bactericidal activity compound composition, in particular to a composition containing picarbutrazox and a succinate-dehydrogenase-inhibitor (SDHIs) bactericide and a preparation thereof and applications of the composition and the preparation. The bactericidal composition comprises a bactericidal activity compound I and a bactericidal activity compound II, the bactericidal activity compound I is the picarbutrazox, and the bactericidal activity compound II is the succinate-dehydrogenase-inhibitor (SDHIs) bactericide. The bactericide composition has the advantages of being wide in control spectrum and free of cross resistance, the using quantity and the using number of the SDHI can be obviously decreased, and the resistance is delayed. The invention also provides the preparation of the bactericidal composition, a preparation method suitable for the composition is designed, the effect of a medicament can be developed to a maximum degree, and the using quantity of the medicament is decreased. The invention also provides the applications of the bactericidal composition and the preparation, so that medicine is guided to be correctly used, and misusing of the medicament is reduced.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a bactericidal active compound composition, in particular to a composition containing picarbutrazox and succinate dehydrogenase inhibitor fungicides and its preparation and application. Background technique [0002] Succinate dehydrogenase inhibitors (SDHIs) fungicides act on complex II on the respiratory chain, namely the succinate dehydrogenase complex (succinate dehydrogenase; SDH), to specifically interrupt the iron-sulfur in the active domain SDHB of the enzyme. The electron transfer between the structural iron-sulfur cluster [3Fe-4S] in protein Ip and ubiquinone affects the respiration of pathogenic fungi, hinders their energy metabolism, inhibits the growth of pathogenic bacteria, and leads to their death, thereby achieving the purpose of sterilization. This type of fungicide has the characteristics of specific action, strong efficacy and long-lasting action, but its action site i...
