Abstract

The invention belongs to the field of agricultural microbial technology, and relates to a bio-control strain DX3 used for preventing and controlling tomatos yellows leaf curl virus and applications thereof. It is identified that DX3 belongs to Bacillus sp.; DX3 is preserved in China General Microbiological Culture Collection Center from January, 31th, 2013; and the strain preservation number is CGMCC NO.7239. The results of a greenhouse experiment show that: the biocontrol strain DX3 is capable of reducing the frequency of toamtos yellows leaf curl virus disease significantly. A biocontrol agent is prepared by using DX3, and is diluted to 100-fold for spray processing; and bio-control effect of toamtos yellows leaf curl virus disease at room temperature can reach 57.38% by spray processing. In addition the bio-control effect under field conditions can reach 51.70 to 53.35%. Therefore, the strain and the bio-control agent prepared by using the strain can be used for preventing and controlling toamtos yellows leaf curl virus and yield increase.

Description

technical field

[0001] The invention belongs to the technical field of agricultural microorganisms, and relates to a biocontrol bacterial strain DX3 for preventing and treating tomato yellow leaf curl virus disease and an application thereof. Background technique

[0002] In recent years, tomato yellow leaf curl virus has been outbreaked continuously in a large area in my country. At present, the occurrence area is more than 200,000 hm2, and the economic loss is billions of yuan, which has constituted a serious threat to the sustainable development of my country's tomato industry. The disease is caused by tomato yellow leaf curl virus (TYLCV) of the genus Begomovirus in the family Geminiviridae and is transmitted by whiteflies. The viral disease has the characteristics of strong epidemic, rapid onset, rapid spread, serious damage, and difficult to control. The plots with severe disease may even cause crop failure, seriously affecting the yield and quality of tomatoes. [0...
