The invention belongs to the technical field of agricultural compositions, and particularly relates to an agricultural composition for promoting disease resistance and quality improvement of fruit trees. The active ingredients of the agricultural composition are geraniol and S-abscisic acid, a field test shows that the mass ratio of geraniol to S-abscisic acid is (8-16): (15-7), the geraniol and S-abscisic acid have a synergistic effect, and the geraniol and S-abscisic acid can remarkably improve the single fruit weight and soluble solids of facility cherries and peaches, improve the anthocyanin content in the facility cherries and improve the vitamin C content in the peaches, so that the yield of the facility cherries and peaches is increased. Meanwhile, the morbidity of the gummosis of the fruit trees is remarkably reduced, and the disease resistance of the tree bodies is enhanced. The invention provides more solutions for solving the problems of frequent gummosis and fruit quality decline in fruit tree cultivation.

The bacillus velezensis C1-17 has been preserved in the China Center for Type Culture Collection (CCTCC) on October 22, 2025, the address is Wuhan City, Hubei province, and the preservation number is CCTCC NO: M 20252290. The bacillus velezensis C1-17 fermentation liquor and the sterile filtrate of the bacillus velezensis C1-17 fermentation liquor provided by the invention can effectively inhibit the growth of pathogenic bacteria such as peach brown rot pathogen, gray mold, peach anthracnose, peach gummosis, peach scab and the like. The bacillus velezensis C1-17 provided by the invention can be used for effectively preventing and treating sterol demethylation inhibitor sensitive strains and resistant strains of peach monilinia.

The invention discloses a microbial agent for preventing and treating cherry branch and leaf diseases and a preparation method thereof, and belongs to the field of agricultural microorganisms, and the method comprises the following steps: strain screening and activation, amplification culture, microbial agent compounding and stability treatment. The invention provides a microbial agent for preventing and treating cherry branch and leaf diseases and a preparation method thereof, aiming at the defects of long effective time, insufficient targeting property and weak stress resistance of a microbial agent in a high-incidence environment of cherry leaf spot disease and gummosis in the prior art, so that the long-acting activity of the microbial agent in a high-temperature, rainy and high-humidity environment is realized; meanwhile, the targeted antagonism capability on target pathogenic bacteria is improved.

The application relates to application of a compound Questiomycin A in prevention and treatment of plant diseases. The compound not only effectively antagonizes Agrobacterium tumefaciens, but also has high efficient antagonistic activity on botrytis, brown rot and gomme.

The utility model discloses a device for preventing and treating pepper gummosis by using bacillus subtilis fermentation filtrate, which relates to the technical field of prevention and treatment of pepper gummosis and comprises two universal ball seats which are respectively arranged on two sides of the lower surface of a vehicle plate; the two first telescopic rods are respectively arranged on the universal ball bodies of the two universal ball seats; the two side wheels are arranged at the ends, away from the universal ball seat, of the two first telescopic rods correspondingly; the pesticide box is arranged on the vehicle plate, and a pesticide inlet pipe is arranged on the side wall of the pesticide box; the two liquid outlet pipes penetrate through the left side wall and the right side wall of the pesticide box respectively, and the ends, extending into the pesticide box, of the liquid outlet pipes are connected with the submersible pump in the pesticide box; the two spraying assemblies are arranged on the left side wall and the right side wall of the pesticide box respectively; the device has the advantages of being convenient to use, reducing the labor intensity of workers and the like.

This invention provides a pharmaceutical composition for controlling peach gummosis and its application, belonging to the field of induction-based disease control technology. The pharmaceutical composition for controlling peach gummosis includes separately packaged salicylic acid and a chemical fungicide; the chemical fungicide includes hexaconazole and prochloraz; the mass ratio of hexaconazole to prochloraz is (4-8):1. This invention alternates the application of salicylic acid with a specific ratio of hexaconazole and prochloraz to peach trees. During the growing season, exogenous application of salicylic acid enhances the plant's resistance to various diseases. Combined with the use of chemical fungicides, this reduces the frequency of fungicide application. Simultaneously, due to the inducing effect of salicylic acid, it also prolongs the effective period of the chemical agents.

This invention relates to PpERF98 The application of genes in regulating resistance to peach gummosis: This invention utilizes genetic engineering techniques to... PpERF98 A specific target fragment was obtained from the open reading frame sequence of a gene, and primers for amplification of the target fragment were designed. The target fragment was fused with the virus-mediated gene silencing (VIGS) vector pCaRNA3 via enzyme digestion to successfully construct the VIGS vector. The VIGS vector was then transformed into peach plants using Agrobacterium-mediated transformation, reducing the... PpERF98 The expression of the gene was used to obtain plant materials resistant to gummosis; the full-length open reading frame primers were SEQ ID NO: 1 and SEQ ID NO: 2. This invention improves the resistance of peach trees to gummosis pathogens through transgenic methods, significantly reduces the incidence of gummosis, and reduces the economic losses caused by peach gummosis.
