Farmers are reminded that high pH soil does NOT provide protection from this disease and resting spores can persist in the soil for as long as 20 years. Avoidance requires careful sanitation of equipment and vehicles that have traveled from one field to the next, but especially from moving from an infested area to a non-infested area (weekend shopping trips to Fargo should end with a car wash, OK?).
