Abstract
Four yeasts (NRRL Y-30213, NRRL Y-30214, NRRL Y-30215, and NRRL Y-30216) and 1 bacterium (NRRL B-30212) have been identified as being superior antagonists capable of suppressing Fusarium head blight (head scab) in cereals, particularly in wheat and barley. Fusarium head blight is primarily caused by the fungus Gibberella zeae (anamorph=Fusarium graminearum).

A biologically pure culture selected from the group consisting of Torula aurea (NRRL Y-30213), an unidentified yeast (NRRL Y-30214), Bacillus sp. (NRRL B-30212), Torula sp. (NRRL Y-30215), and Cryptococcus nodaensis (NRRL Y-30216).
A method for suppressing Fusarium head blight in a cereal plant comprising applying to a seed head of said plant an effective amount of a microbial antagonist selected from the group consisting of NRRL Y-30213, NRRL Y-30214, NRRL B-30212, NRRL Y-30215, and NRRL Y-30216.
