Problems solved by technology

However, as a typical soil-borne disease, chemical control can play a certain role in the prevention and control of white silkworm. However, the long-term and large-scale application of fungicides not only deteriorates the soil environment, but also leads to the development of drug resistance of pathogenic bacteria, which seriously damages the agricultural ecosystem.

Embodiment 1

[0030] This embodiment provides a bactericidal composition of Clonospora pink spores and boscalid, which is composed of clonospora pink spore wettable powder and boscalid wettable powder with a mass percentage of 5:1;

[0031] Wherein, the content of the original drug in the boscalid wettable powder is 50%;

[0032] Wherein, the content of spores in the clonosporum pink spore wettable powder is 1 × 10 8 CFU / g.

Embodiment 2

[0034] This embodiment provides a bactericidal composition of Clonospora pink spores and boscalid, which is different from Example 1 in that the wettable powder of Clonosporium pink spores and boscalid bacteria with a mass percentage of 99.93:0.07 are provided. Composition of amine wettable powder, wherein, the content of spores in the said pink helix spore wettable powder is 3×10 8 CFU / g.

Embodiment 3

[0036] This embodiment provides a bactericidal composition of Clonospora pink spores and boscalid, which is different from Example 1 in that the wettable powder of Clonosporium pink spores and boscalid bacteria with a mass percentage of 99.8:0.2 are provided. Composition of amine wettable powder; wherein, the content of spores in the said pink helix spore wettable powder is 3×10 8 CFU / g.

Abstract

The invention relates to a bactericidal composition containing Clonostachys rosea spores and boscalid. The bactericidal composition is prepared from the Clonostachys rosea spores and the boscalid, wherein the weight ratio of the Clonostachys rosea spore powder to the boscalid is (80-99.93):(0.07-20). The sterilization composition provided by the invention is suitable for preventing and treating crop diseases caused by sclerotium rolfsii, such as southern blight, and can be used for treating soil of a protected land. The prevention and treatment effect of the sterilization composition is obviously improved compared with that of a single agent, and the usage amount is relatively small; and the pesticide cost is greatly reduced, and the pollution to the soil environment can be further reduced.

Description

technical field [0001] The invention relates to a compound bactericidal composition and an application thereof, in particular to a compound bactericidal composition of Clonosporium pinkhelix spores and boscalid and an application thereof. Background technique [0002] Sclerotium rolfsii is an important plant pathogen with a wide range of hosts and can infect more than 500 species of plants in more than 100 families, including pepper, tomato, eggplant, peanut, tobacco and other important economic crops. Sclerotinia sclerotiorum survives the winter in the soil or debris by forming sclerotia with strong stress resistance, and has strong adaptability and long survival time. As the primary infection source, the sclerotium invades the rhizome of the host plant near the ground, causing the cortex to rot, and even the plants wilt and die, causing serious economic losses. [0003] Boscalid, common name is boscalid, chemical name is 2-chloro-N-(4'-chlorodiphenyl-2-yl) nicotinamide, m...
