This invention discloses a compound fungal agent containing Penicillium citrinum and Trichoderma guizhouense, wherein the Penicillium citrinum is Penicillium citrinum (… Penicillium citrinum NJAU-T106, the Guizhou Trichoderma is Guizhou Trichoderma ( Trichoderma guizhouense NJAU4742. This invention also discloses its preparation method and its application in promoting banana plant growth, increasing banana yield, and controlling banana wilt disease. This invention screened Penicillium citrinum (NJAU4742) from banana disease-suppressing soil to obtain a strain with good biocontrol and growth-promoting effects. Penicillium citrinum The study used NJAU-T106 and innovatively combined it with Trichoderma guiyuanensis NJAU4742 to construct a synergistic system of Penicillium citrinum and Trichoderma guiyuanensis. This effectively reduced the incidence of banana wilt disease while better promoting banana plant growth and increasing banana yield, thereby driving the green and sustainable development of the banana industry.

This invention belongs to the field of potato scab control technology, specifically relating to a fungal-agent composition for controlling potato scab and its application. The fungal-agent composition for controlling potato scab provided by this invention comprises the following raw materials: a chemical control agent for potato scab and a compound fungal agent; the volume ratio of the chemical control agent to the compound fungal agent is 75-150:5000; the compound fungal agent includes *Bacillus belyceta* BEV2 and *Bacillus atrophus* FM2-4. Using the fungal-agent composition of this invention can reduce the dosage of chemical agents by at least half, while providing rapid, long-lasting, and effective control of potato scab, and also taking into account the advantages of environmental friendliness.

This invention discloses a Bayer conjugation yeast strain that is resistant to lactic acid stress and produces ethanol and flavor compounds in high yields, and belongs to the field of microbiology. The Bayer conjugation yeast CCTCC NO:M2023729 of this invention was selected from Daqu, a Chinese jiangxiang type baijiu (Chinese liquor), and this strain not only tolerates lactic acid stress but also has the ability to decompose lactic acid. Furthermore, it can produce ethanol and various flavor substances in high yields under lactic acid stress. When this strain was prepared as a fungal agent and applied to the fermentation process of jiangxiang type baijiu, the content of ethanol and flavor substances in the jiubei (Chinese liquor) could be significantly improved.

This invention belongs to the field of biological breeding, and specifically relates to a root-loving oligotrophomonad strain QD20230421 and its application in cultivating high-yield morel mushrooms. The root-loving oligotrophomonad QD20230421 provided in this application is classified and named... Stenotrophomonas rhizophila This strain was deposited at the China Center for Type Culture Collection (CCTCC) on March 9, 2026, with accession number CCTCC NO: M2026389. This strain is a beneficial bacterium for morel mushrooms. Introducing it into the mycelial cells of morel mushrooms to establish an endosymbiotic relationship, or preparing it as a fungal agent and mixing it with the original or cultivated morel mushroom spawn, can enhance the growth capacity of morel mushrooms, promote earlier primordia formation, increase the fruiting rate, and increase the yield of artificially cultivated morel mushrooms. It provides microbial germplasm resources for endosymbiotic breeding technology and spawn production of morel mushrooms, which is beneficial for the selection of high-yielding morel mushroom strains and promotes the sustainable and stable development of the morel mushroom industry.

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.
