METHODS FOR CONTROLLING ABOVE-GROUND PLANT DISEASES USING ANTIBIOTIC-PRODUCING STRAINS OF (BACILLUS SP.)

摘要

The present invention provides methods of preventing and treating above-ground fungal and bacterial infections in plants comprising the step of applying to the plant an effective amount of at least one antibiotic-producing Bacillus sp. bacterial strain AQ175 having ATCC Accession No. 55608, AQ177 having ATCC Accession No. 55609 or AQ178 having ATCC Accession No. 53522 or at least one antibiotic produced by the strains. The invention includes methods of preventing and treating above-ground fungal and bacterial infections in plants using whole broth cultures or supernatants obtained from cultures of the bacterial strains or antibiotics produced by the bacterial strains. The invention also includes preventing and treating above-ground plant diseases using more than one antibiotic-producing bacterial strain, a combination of whole broth and/or supernatant obtained from the bacterial strains and combinations of the antibiotics produced by the bacterial strains.
