Application of lime to soil with an initial pH of 4.8 raised the pH to about 6.5 and maintained it at that level during the 2 yr of the study. Conversely, sulfur application had no effect on soil pH. In the first season after liming, Cephalosporium stripe incidence was 36.1 and 21.8% in the untreated and limed plots respectively; corresponding incidences for the second season were 30.4 and 5.7%. No corresponding yield increase was noted from Cephalosporium stripe control because of severe take-all development in the limed plots.
