Embodiment 1

[0028] This embodiment provides a compound bactericidal composition, which is composed of clonosporium pink spore wettable powder and fludioxonil wettable powder with a mass percentage of 9:1;

[0029] Wherein, the content of the original drug in the described fludioxonil wettable powder is 50%;

[0030] Wherein, the content of spores in the clonosporum pink spore wettable powder is 1 × 10 8 CFU / g.

Embodiment 2

[0032] This embodiment provides a compound bactericidal composition, which differs from Example 1 in that it is composed of pink Clonosporium spore wettable powder and fludioxonil wettable powder with a mass percentage of 99.98:0.02, wherein the pink The content of spores in Clonosporium heliconia spore wettable powder is 3×10 8 CFU / g.

Embodiment 3

[0034] This embodiment provides a compound bactericidal composition, which is different from Example 1 in that it is composed of pink clonosporium spore wettable powder and fludioxonil wettable powder with a mass percentage of 99.93:0.07; wherein, the pink The content of spores in Clonosporium heliconia spore wettable powder is 3×10 8 CFU / g.

Abstract

The invention relates to a compound bactericidal composition and application thereof. The compound bactericidal composition comprises spores of Clonostachys rosea and fludioxonil, and the weight ratio of the spores of the Clonostachys rosea to the fludioxonil is (90-99.98):(0.02-10). The compound bactericidal composition provided by the invention is suitable for preventing and treating crop diseases caused by sclerotium rolfsii, such as capsicum southern blight, and can be used for treating soil of a protected land; and the prevention and treatment effect is obviously improved compared with that of a single agent, the dosage is relatively small, the pesticide cost can be reduced, and pollution to the soil environment is reduced.

Description

technical field [0001] The invention relates to a compound bactericidal composition and an application thereof, in particular to a compound bactericidal composition containing spores of Clonosporium pinkhelix and fludioxonil and an application thereof. Background technique [0002] The chemical control of plant soil-borne diseases requires a large amount of chemicals, especially in protected areas, resulting in excessive residues and pathogenic bacteria developing drug resistance. Biological control is friendly to the environment. The mixed agent of biocontrol bacteria and chemical pesticide can improve the control effect of biological control and reduce the amount of chemical pesticide application in disease control. It is expected to prevent plant pathogens from developing drug resistance and achieve stable and long-lasting prevention effect. Therefore, chemical and biological synergistic control of plant diseases has received more and more attention, which is beneficial ...
