Abstract

The invention discloses fungal inoculant for controlling bacterial wilt of tomato and a preparation method thereof, which belongs to the technical field of biological control of vegetable disease. The trichoderma gamsii strain 6-18 No. 3335 in the CGMCC is used as the strain, the Martin's solid medium is used as the slant medium, the potato sucrose liquid medium is used as the shaking flask strain medium and fermenter medium, and the liquid or solid fungal inoculant is prepared through multi-stage fermentation. The trichoderma gamsii strain is firstly used as the strain and prepared into the fungal inoculant through fermentation, thereby providing a new effective path for the biological control of bacterial wilt of tomato; the fungal inoculant achieves the disease control effect of more than 50%, thereby reducing the use amount of pesticides, and reducing the pollution to environment; the raw material of the fungal inoculant is rich, the fermentation process is simple, and the production cost is low, thus the fungal inoculant can be popularized and applied to the tomato planting areas and pesticide manufacture enterprises.

Description

Technical field

[0001] The invention relates to the technical field of biological control of vegetable diseases, in particular to a fungal agent for preventing and curing tomato bacterial wilt and a preparation method thereof. Background technique

[0002] Tomato bacterial wilt is caused by Ralstonia solanacearum (smith) Yabuuchi et al. It is a devastating soil-borne disease that spreads widely around the world. Tropical and subtropical countries and regions, such as: Serious occurrences occurred in the Americas, Japan, India, the Philippines, Taiwan, Guangdong, Zhejiang, Fujian, Jiangsu, Hubei, Sichuan, and Chongqing. The disease can cause large-scale wilting and death of plants. The incidence rate of general fields is 10%-15%, and the incidence rate of severely ill fields is as high as 80%-98.5%, which leads to a serious decline in tomato production and major economic losses.

[0003] R. solanacearum is a soil-habiting bacteria that can survive for a long time in soil without a ...
