Spores initiate new infections on the lower leaf sheaths. Tillering seedlings are more susceptible than younger seedlings. The fungus is most active at 50 F. Infections are prevented above 60 F. Infections are favored by dense stands, high soil moisture, and high humidity. In 2000, the epidemic was associated with abnormally high rainfall in January, February, and March and mild temperatures during fall and winter. However if a field was attacked this year, inoculum of the fungus will be present for next year, so special management might be justified.
Crop rotation is the best way to reduce the inoculum and thus reduce the risk of occurrence.
One full year out of wheat may be enough, but two years would be even better. Theoretically, residue borne diseases like strawbreaker should be reduced by tillage or plowing. Surprisingly, tillage does not seem to be very effective for controlling strawbreaker. In some reports, disease was actually lower in no-till compared to plowing or chisel tillage. This could be due to thinner stands under no-till.
