Abstract

The invention discloses Bacillus tequilensis and application thereof. The strain is preserved in the China General Microbiological Culture Collection Center on December 7, 2020, the preservation number is CGMCC No. 21317, and the preservation name is Bacillus tequilensis M408F10-3F8. The strain is applied to the field of agricultural biological control, a biological membrane can be formed to be stably colonized at the plant rhizosphere, a high and broad-spectrum inhibition effect can be generated on 12 plant pathogenic fungi and oomycetes, and IAA can be generated to promote plant growth. The control effects of the Bacillus tequilensis bacterial suspension and fermentation liquor on cucumber fusarium wilt potted plants reach 50.00% and 58.00% respectively, the control effect is equivalent to that of a medicament control carbendazim, an obvious growth promoting effect is achieved on cucumbers, and the Bacillus tequilensis is a biocontrol strain with excellent performance and has good development and application prospects.

Description

technical field

[0001] The invention belongs to the technical field of agricultural biological control, and in particular relates to a strain of Bacillus tequilensis and an application thereof. Background technique

[0002] Plant diseases pose a serious threat to world food production and security. For a long time, the use of chemical pesticides and fertilizers has aggravated problems such as environmental pollution, bacterial strain resistance, and soil micro-ecological imbalance. There is an urgent need to discover microbial products that can replace chemical pesticides and fertilizers. Despite the existence of a large number of microbial products, due to their low colonization ability and short duration in the field, mining broad-spectrum and high-efficiency microorganisms from plant-related microbial communities such as rhizosphere and root endophytes has become an important topic at home and abroad Scholars' research hotspots.

[0003] Bacillus is a kind of Gram-posi...
