Problems solved by technology

At present, ginger bacterial wilt is usually prevented by selecting ginger varieties with strong disease resistance and interplanting crops, but due to the interference of factors such as environment and management, the control effect is not ideal
In addition, because ginger blast itself is a soil-borne disease, the control effect of chemical preparations such as Qingkuling and Jiangwenjing will be limited. In addition, the pathogenic bacteria are prone to drug resistance, and it will also cause serious pollution to the environment and cause drug residues.

Embodiment

[0032]A biopesticide composition of the present invention comprises 10-50% of Bacillus amyloliquefaciens TR-01 (Bacillus amyloliquefaciens TR-01) and 50%-90% of 20% thysencopper suspension concentrate (SC) by weight percentage . Among them, the 20% thysen copper suspending agent is provided by Zhejiang Dongfeng Chemical Co., Ltd., and the concentration of 20% thysen copper suspending agent is 100-500mg·kg -1 ; Bacillus amyloliquefaciens TR-01 can be a bacterial strain suspension or a spore precipitation, and the strain content in the bacterial strain suspension is 2 billion to 10 billion strains / gram.

[0033] The Bacillus amyloliquefaciens TR-01 (Brevibacillus brevis) TR-01 is an endophytic bacterium isolated from tobacco plants in diseased areas, and it is preserved in the General Microbiology Center of China Committee for the Collection of Microorganisms, and the preservation number is: CGMCC No. 13485, the preservation time is December 23, 2016, and the preservation addre...

Abstract

The invention discloses a biological pesticide composition. The biological pesticide composition is prepared from bacillus amyloliquefaciens TR-01 and N,N'-methylene-double copper. The invention further discloses a preparation method of the biological pesticide composition and application of the biological pesticide composition in controlling of ginger blast. The biological pesticide composition can effectively control the ginger blast, and in the application, the synergistic use effect of the bacillus amyloliquefaciens TR-01 and the N,N'-methylene-double copper is significantly higher than the use effect of separate single agents, and the stable control effect is ensured; and the usage amount the N,N'-methylene-double copper is greatly reduced, environmental pollution is reduced, and theimpact on safety and health of people is reduced.

Description

technical field [0001] The invention relates to the technical field of fungicides, and more specifically relates to a biopesticide composition, a preparation method thereof and an application in preventing and treating ginger blast. Background technique [0002] Chemical pesticides have outstanding advantages in the prevention and control of harmful organisms. They have quick effects and strong knockdown power. They can kill harmful organisms within a few days or even hours. The operation and use are simple and direct, and the control spectrum is wide. Some products can target many species. Agricultural pests, and the effect is remarkable, the economic benefit is remarkable, and there is still a large demand in the domestic and foreign markets. At present, 35% of the world's crop yields are still lost due to the heavy use of pesticides. According to a survey by the Food and Agriculture Organization of the United Nations (FAO), the amount of grains taken away by pests and di...
