Soil or volcanic ash placed around the base of winter wheat (dirting) in the spring increased the severity of strawbreaker foot rot incited by Pseudocercosporella herpotrichoides. The effects of volcanic ash and soil were similar. In some cases dirting reduced yield, in some cases it increased yield, and in some cases it did not affect yield.
