Problems solved by technology

[0004] Combining different active ingredients of pesticides, the synergistic composition can not only significantly improve the actual control effect, reduce the dosage and cost, but also help to avoid the occurrence of bacterial resistance and delay the emergence of drug resistance. An effective way to solve the problems of high cost, narrow bactericidal spectrum and easy resistance in the process of single-dose application of pesticides

Abstract

The invention relates to a bactericidal composition. Effective components of the bactericidal composition are famoxadone (A) and a pyrimidine-type bactericide (B), wherein the pyrimidine-type bactericide is ethirimol, ethirimol sulfonic ester or dimethirimol; the mass ratio of A to B is between 80:1 and 1:80; and the weight percentage content of active components in the composition is 5 to 80 percent. The composition can be prepared into cream, suspending agents, wettable powder, water dispersible granules, micro-emulsions and other forms of agents. The bactericidal composition is applied in farmland, orchards and other places, and is used to prevent and control various plant diseases, particularly powdery mildew on grain, vegetables, fruit trees and other crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing oxafeconone and a pyrimidine bactericide, and belongs to the field of agricultural bactericides. Background technique [0002] Famoxadone is a broad-spectrum fungicide, mainly used to control important diseases caused by ascomycetes, basidiomycetes, and oomycetes, such as powdery mildew, rust, glume blight, net spot, downy mildew, late blight etc. [0003] Falfazone is an inhibitor of mitochondrial respiration, but its electron transfer site for inhibiting mitochondria is very single, and bacteria are prone to adaptive mutations to the drug, which reduces or even invalidates the control effect of the drug. At present, there have been reports of drug resistance abroad, and there is a greater risk in long-term use of a single agent. [0004] Combining different active ingredients of pesticides, the synergistic composition can not only significant...
