This year, a Morrill County grower experienced a severe outbreak of common bunt, or stinking smut, in three irrigated winter wheat circles. This fungal disease, caused by Tilletia species, infects wheat during germination under cool, wet conditions. The first sign of infection was a cloud of black dust during harvest, indicating spore release from the infected wheat.
Upon inspection, the wheat kernels were filled with black, powdery spores emitting a foul odor, making the affected grain undesirable as livestock feed. The source of the infection was traced back to the grower's own seed, harvested from a previous low-level infestation. This unintentional reuse of infected seeds led to widespread contamination.
Experts recommend several measures to manage common bunt effectively: using resistant wheat varieties, treating seeds with appropriate fungicides, practicing crop rotation, maintaining field sanitation, and ensuring clean equipment. Local agricultural extension services can provide guidance on resistant cultivars and fungicide treatments.
The use of certified seed is strongly advised over bin-run seeds to prevent diseases like common bunt and the spread of undesirable weeds. By adopting these integrated management practices, growers can safeguard their crops against common bunts and enhance overall yield and quality.
