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 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.
