This invention discloses a microbial combination with both disease prevention and growth promotion effects, along with its co-cultivation and application. Addressing the issues of insufficient synergistic effect and the need to improve the biocontrol and growth-promoting properties of existing co-cultivation technologies, this invention screens a specific strain combination (*Polyspora pinkis* NF-06 and *Bacillus belyssus* YB-1652) and employs a corresponding co-cultivation process: a specific semi-synthetic culture medium with soybean meal as the main nitrogen source, followed by simultaneous inoculation and culture. This process stably stimulates the synergistic interaction between the two strains, resulting in a product with a mortality rate of over 95.3% against second-instar larvae of the southern root-knot nematode, and significantly promotes the growth of crops such as tomatoes, achieving a synergistic effect of controlling root-knot nematodes and promoting plant growth.

This invention discloses a strain of *Backusella circina* and its application. The strain number of *Backusella circina* is JSAFC 2057, which was deposited at the China General Microbiological Culture Collection Center (CGMCC) on September 23, 2024, with accession number CGMCC No. 41522. This fungal agent can significantly inhibit the survival activity of the fall webworm (*Triplophysa fulvidraco*), reducing the survival activity of fall webworm larvae to zero after 7 days of treatment and culture. The fungus provided by this invention is a biocontrol fungus for the control of the major pest, the fall webworm. It is characterized by strong pathogenicity against fall webworm larvae, environmental safety, and low likelihood of inducing pesticide resistance in pests, and can be applied to the biological control of the fall webworm.
