Abstract: A novel antibiotic-producing Streptomyces sp. is provided that exhibits antifungal activity only on certain specific plant pathogens. Also provided is a method of treating or protecting plants from fungal infections comprising applying an effective amount of an antibiotic-producing Streptomyces sp. having all the identifying characteristics of NRRL Accession number B-30145. The invention also relates to fungicidal compositions comprising this novel Streptomyces strain and the antibiotics and metabolites produced by this strain either alone, or in combination with other chemical and biological pesticides.

Abstract: A novel strain of Streptomyces galbus that produces metabolites and exhibits pesticidal activity is disclosed. In addition, a supernatant of the novel strain with pesticidal activity is disclosed. An ethyl acetate-soluble, small molecular weight, alkali stable, metabolite produced by the novel strain Streptomyces galbus with pesticidal activity against lepidopteran insects is provided. Also included are methods for fermenting the novel strain of Streptomyces galbus and increasing the bioactivity of the pesticidal activity. Also included are methods for protecting or treating plants from caterpillars comprising the step of applying to a plant an effective amount of the novel Streptomyces galbus strain, the metabolites produced by the strain, or a combination thereof.

Abstract: A novel antibiotic-producing Bacillus sp. is provided that exhibits antifungal activity only on certain specific plant pathogens and no antibacterial activity is provided by this invention, as well as a biologically pure culture of a strain having all the identifying characteristics of this strain. Also provided is a method of treating or protecting plants, fruit and roots from fungal infections by applying an effective amount of these strains, supernatants produced by these strains or a metabolite isolated from these strains. The invention further encompasses the synergistic fungicidal effect of using a strain of NRRL Accession Nos. B-30087 together with B-21661 (AQ 713).
