The invention relates to a bactericidal composition with active ingredients to be
pyrazole-kresoxim-methyl and polyoxin, as well as the application thereof. The bactericidal composition contains the active ingredients of the
pyrazole-kresoxim-methyl and the polyoxin, the weight ratio of which are 1:40-40:1 and the weight percentages are 1%-40%; and the bactericidal composition can be prepared into
wettable powder,
water dispersible granules, a suspending agent, aqueous
emulsion, micro-
emulsion, soluble concentrate or other formulations. The bactericidal composition at least contains a carrier and an accessory ingredient, wherein at least one is a surface
active agent which can be an emulsifier, a dispersant, a
humectant or a penetrant. The carrier can be water,
organic solvent or latent
solvent, and filling material. A stabilizing agent, a
thickening agent, a defoaming agent, and a cementing agent can be added. The bactericidal composition is used for preventing and curing a plurality of
plant diseases caused by pathogenic fungi such as oomycetes, ascomycetes, basidiomycetes and deuteromycetes. The bactericidal activity is enhanced and the bactericidal spectrum is widened via combination,so that the bactericidal composition has widened
usable range and reduced cost, and can cure a plurality of diseases, thus reducign input and increasing production benefit.
