Data obtained in 1972, 1973, and 1974 showed that ecofallow (reduced tillage) decreased the incidence of stalk rot in grain sorghum grown in a winter wheat-grain sorghum-fallow rotation. Stalk rot averaged 39% in the conventionally tilled plots, whereas, the incidence of stalk rot in the minimum- and nontilled plots averaged 23% and 11%, respectively.
