Aspergillus flavus
To protect tree nuts and corn plants that are affected by A. flavus  treating the plants with the yeast Pichia anomala reduces the growth of A. flavus. Treating pistachio trees with P. anomala inhibited the growth of A. flavus up to 97% when compared to untreated trees.   The yeast successfully competes with A. flavus for space and nutrients, ultimately limiting the growth of A. flavus.
