Abstract

The invention discloses an azoxystrobin-containing bactericidal composition and its application. The composition contains active components of azoxystrobin and bacillus cereus which are mixed into a wettable powder, a suspending agent and water dispersible granules according to a certain proportion. The above bactericidal composition is applied in controlling a plurality of plant diseases caused by pathogenic fungi. The above bactericidal composition is especially applied in controlling any one disease selected from rice sheath blight, Pyricularia oryzae, cucumber downy mildew, grape downy mildew and apple rust disease. Synergism of the invention is substantial: as action sites on target fungi are increased, the bactericidal effect of the composition obtained after mixing is obviously raised in comparison with that of a single dose; after the drug effect is raised, application amount of the effective components and the drug application frequency are minimized, drug application cost can be reduced, and the environmental pollution is decreased; as single selection pressure of pathogen can be mitigated, resistance of pathogen can be avoided or delayed; and insecticidal spectrum can be enlarged, and the composition can be used to treat a plurality of diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing azoxystrobin. Background technique [0002] Diseases caused by plant pathogenic fungi account for about 70-80% of plant diseases. Several or even dozens of fungal diseases can be found on a crop. Many fungal diseases have obvious geographical distribution due to different pathogens and hosts. For example, mildew, anthracnose, and blight have many types in subtropical and tropical regions and cause serious damage; Leaf spot, Sclerotinia caused by Sclerotinia mainly occurs in temperate zones. Some fungi are weakly parasitic in the north and do not cause disease; but they can cause serious diseases in the tropics and subtropics. Downy mildew, powdery mildew, white rust, smut, powdery rust, smoke mold, mole, mold, mushroom, cotton floc, granule, rope, and mucilage are common and small black dots etc. [0003] Due to the prominent airflow and wat...
