Livingston, J.E. (1945) Charcoal rot of corn and sorghum (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 136)
In Nebraska, the charcoal rot caused considerable damage to the 1940 grain sorghum crop in the south central counties, and the following year it caused serious lodging and reduction of yield in both corn and sorghum in all sections of the state. Field observations indicated that some varieties of sorghum were damaged less than others; thus it appeared desirable to test thoroughly all varieties to determine whether any were sufficiently resistant to be recommended for field planting or to be used in a breeding program. It seemed desirable to study the influence of soil environment on infection and the development of stalk rot before attempting an extensive varietal testing program. Such information would also serve as a guide in predicting the geographic distribution of the disease and the severity of the stalk rot in a given season.
