Abstract
Fungal/bacterial antagonist combinations, a seed coated with one of the combinations and a plant protected from plant pathogens by one of the combinations. The invention is also a fungal/bacterial antagonist combination comprising a Trichoderma virens fungal antagonist and a Bacillus subtilis var. amyloliquefaciens (Bacillus amyloliquefaciens) bacterial antagonist and its use for controlling plant pathogens as a biocontrol agent, bio-pesticide or bio-fungicide. The invention also finds utility as a fungal/bacterial antagonist combination applied to the seed, stalk or leaf that results in an increase in plant yield. Control of early and late season stalk and root rot caused by fungi such as Fusarium, Phythium, Phytophthora and Penicillium in tomatoes, peppers, turf grass, soybeans, sunflower, wheat and corn is achieved.
