The invention provides an antagonistic strain 12a producing volatile antibacterial gas and its application in preventing and controlling fruit and vegetable diseases. The antagonistic strain 12a disclosed in the present invention is Bacillus vallismortis, and the preservation number is CGMCC No.12179. The antagonistic bacterial strain 12a of the present invention is obtained by collecting the rhizosphere soil of peach trees in Feicheng peach orchard without applying chemical fertilizers and pesticides, and the volatile antibacterial gas produced in its fermentation liquid has a strong antagonistic effect on peach brown rot (Monilinia fructicola) , while treating apple brown spot caused by Alternaria mali, sweet potato black spot caused by Ceratocystis fimbriata Ellis.Et Halsted, and citrus blue spot caused by Penicillium italicum Wehmer. Mildew and winter jujube black spot caused by Alternaria alternata also have obvious inhibitory effect, and can effectively prevent and control a variety of fruit and vegetable diseases. The biological control potential strains have broad market application prospects.

The invention relates to benzoxazepin bacteriostats and a preparation method thereof. The chemical structural formula is shown in the specification, wherein substituents R1, R2 and R3 are chloro, bromo, methyl, normal-butyl, p-chlorophenyl, methyl acetate groups, tertiary butyl or cyclohexyl, and positions, the number and conjugate positions of the substituents are not fixed. According to the synthetic method, ortho-azidobenzoic acid compounds and aryl ketoaldehyde compounds and in-situ formed isocyanide compounds are subjected toa Passerini reaction, a formed product and triphenylphosphine are subjected toa Staudinger reaction, and polysubstituted benzoxazepin heterocyclic compounds and other important heterocyclic compounds are produced through ring closing of an intramolecular aza-Wittig reaction. The key point of the invention is to provide one novel synthetic method which adopts fewer steps and has high yield to synthesize the novel benzoxazepin compounds. The compounds have better inhibitory activity on Rhizoctonia solani, Penicillium digitatum and Penicillium italicum and can be used as the bacteriostats.

The invention discloses hanseniaspora uvarum; the bacterial strain is Y68; the preservation number is CGMCC No. 8042. The hanseniaspora uvarum Y68 has the inhibiting effect on post-harvest monilinia fructicola of peaches and cherries, post-harvest botrytis cinerea of grapes, tomato botrytis, post-harvest botrytis cinerea of apples, post-harvest penicillium italicum of apples and post-harvest penicillium italicum of pears, and has the inhibiting effect on post-harvest brown rot of peaches, cherry brown rot, grape botrytis, tomato botrytis, post-harvest botrytis of apples, post-harvest penicilliosis of pears and post-harvest penicilliosis of apples. The hanseniaspora uvarum Y68 specifically has obvious inhibiting effect on the botrytis cinerea; the diameters of inhibition zones are all greater than 10 mm.

The invention relates to citrus endophytic actinomycetes with antibacterial activity on various plant pathogens, belonging to the technical field of microbes. The endophytic actinomycetes are Streptomyces sp. R1020 which was registered and collected in China General Microbiological Culture Collection Center on March 17, 2014 with the collection number of CGMCC No. 8923.
