The invention relates to a bactericidal composition with active ingredients to be pyrazole-kresoxim-methyl and thiram, and belongs to the bactericidal composition pesticide technology field. The bactericidal composition contains the active ingredients to be the pyrazole-kresoxim-methyl and the thiram, the weight ratio of which are 1:40-40:1 and the weight percentages are 1%-90%; and the bactericidal composition can be prepared into wettable powder, water dispersible granules, a suspending agent, aqueous emulsion, micro-emulsion, 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 according to the different preparation formulations. A stabilizing agent, a thickening agent, a defoaming agent, a cementing agent and other functional accessory ingredients can be added when necessary. The bactericidal composition can be used for preventing and curing a plurality of plant diseases caused by oomycetes, ascomycetes, basidiomycetes, deuteromycetes, and so on, so as to play an important role in enhancing effects, curing diseases, reducing cost, delaying pesticide resistance, etc.
Description
technical field [0001] The invention relates to a fungicidal composition with pyraclostrobin and thiram as active ingredients and an application thereof, belonging to the technical field of fungicidal composition pesticides. Background technique [0002] Pyraclostrobin is a new type of methoxyacrylate (Strobilurins) broad-spectrum fungicide, which has protection, treatment, good penetration and systemic effects, and is effective against ascomycetes, basidiomycetes, oomycetes and half-knowledge fungi. All showed significant antibacterial and bactericidal activities, and were widely used in the prevention and control of diseases of fruit trees, vegetables and cereal crops. The bactericide belongs to the inhibitor of mitochondrial respiration, that is, it blocks the electron transfer between cytochrome b and c1 in the respiratory chain, inhibits the respiration of mitochondria, interferes with the energy supply of cells, causes cells to die, and thus exerts a bactericidal effec...
