Compositions and methods include a new strain of Bacillus amyloliquefaciens having activity against plant pathogens. The compositions are useful for benefiting plant growth and/or conferring protection against a pathogenic infection when applied to plant foliage, flowers, fruits, bark, roots, seeds, callus tissue, grafts, cuttings, surrounding soil or growth medium, and soil or growth medium concomitant with sowing seed and planting callus tissue, grafts, and cuttings. In one example, the Bacillus amyloliquefaciens RTI472 strain can be delivered to the plant as part of an integrated pest management program, with other microbial or chemical insecticides, fungicides, nematicides, bacteriocides, herbicides, plant extracts, and plant growth regulators.本發明係關於包括解澱粉芽抱桿菌之新菌株之組合物及方法,該菌株具有對抗植物病原體之活性。當該等組合物施用於植物葉、花、果實、莖皮、根部、種子、癒合組織、移植物、插條、周圍土壤或生長介質及伴隨播種及種植癒合組織、移植物及插條之土壤或生長介質時,可用於使植物生長獲益及/或賦予保護以避免病原性感染。在一個實例中,解澱粉芽孢桿菌RTI472菌株可作為綜合性害蟲管理方案之一部分,與其他微生物或化學殺蟲劑、殺真菌劑、殺線蟲劑、殺菌劑、除草劑、植物提取物及植物生長調節劑一起輸送至植物。
