Fusarium should be visible by now, if you have any Bio-Aid trials on wheat.
Agronomist Derek Cattoor advises to look for an orangish/pink powder at the base of the floret. “Many times, the head will not pollinate above that point of infection,” Cattoor says. “It is also identifiable by small, shriveled grains with pink ends.”
Fusarium, commonly referred to as head scab, is currently the most economically important wheat disease in the U.S. as it will reduce yields, according to the Crop Protection Network. The fungal disease will spread upward and downward by sequentially infecting spikelets. Infected “tombstone” kernels will blow away with chaff.
Bio-Aid, our first EPA-registered fungicide, is recommended to suppress and control fusarium. Delivering an initial contact kill, Bio-Aid provides contact control of a wide range of fungal pests while being cost comparative at two applications versus popular commercial competitors.
