A biocontrol agent and a method of use thereof for controlling diseases caused by fungal pathogens in plants. In one aspect of the invention, novel strains of Gliocladium roseum exhibiting antagonistic effects against plant pathogens are used as biocontrol agents. Most preferably, a novel strain Gliocladium roseum ACM941 (ATCC #74447) is used in a treatment effective against fungal pathogens of plants. The biocontrol agent of the present invention may be used in the treatment of seeds, soil or plants to effectively protect against plant diseases caused by fungal pathogens. The biocontrol agent is particularly effective against fungal infections of pea, bean, canola, wheat, barley, beet, broccoli, brussel sprouts, cabbage, canola, califlower, cucumber, egg plant, pepper, tomato, marigold and other horticultural and ornamental plants, caused by Alternaria alternata, Aphanomyces euteiches, Ascochyta spp., Bipolaris sorokiniana, Fusarium graminearum, Fusarium oxysporum f.sp. pisi, Fusarium solani f.sp. pisi, Fusarium spp. Mycosphaerella pinodes, Pythium spp., Rhizopus sp., Rhizoctonia solani, and Sclerotinia sclerotiorum.
A biologically pure culture of a strain of a microorganism Gliocladium roseum exhibiting antagonistic effects against a plant pathogen, said microorganism having the identifying characteristics of ATCC #74447.
A composition comprising:
A method of protecting a plant from fungal infection comprising the steps of contacting the plant during a stage of the growth of said plant or contacting a seed of said plant with a strain of a microorganism Gliocladium roseum exhibiting antagonistic effects against a fungal plant pathogen, said strain having the identifying characteristics of ATCC #74447.
A method of protecting pea plants against PRRC pathogens, said method comprising:
A biologically pure culture of a strain of a microorganism Gliocladium roseum exhibiting antagonistic effects against a plant pathogen, characterized by bands of 1.3 kb following DNA amplification with UBC519 primer and of 0.5 kb and 1.3 kb following DNA amplification with UBC521 primer.
