Compositions and methods include a new strain of Bacillus amyloliquefaciens having growth promoting activity and 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. The compositions containing the Bacillus amyloliquefaciens RTI301 strain can be applied alone or in combination with other microbial, biological, or chemical insecticides, fungicides, nematicides, bacteriocides, herbicides, plant extracts, plant growth regulators, and fertilizers. In one example, the Bacillus amyloliquefaciens RTI301 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.本發明係關於包含解澱粉芽孢桿菌之新菌株之組合物及方法,該菌株具有促生長活性及對抗植物病原體之活性。該等組合物在施用於植物葉、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適用於有益於植物生長及/或賦予保護以避免病原性感染。含有解澱粉芽孢桿菌RTI301菌株之組合物可單獨或與其他微生物、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、植物生長調節劑及肥料組合施用。在一個實例中,解澱粉芽孢桿菌RTI301菌株可作為綜合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。
