Basal stalk rot and root rot of grain sorghum (Sorghum bicolor) were reproduced in plants grown in the greenhouse in Fusarium moniliforme-infested soil at optimal soil moisture until flowering, then subjected to a gradual development of severe moisture stress between flowering and the middough stage, followed by rewetting. Stalk rot did not develop and root rot was not severe in plants grown to maturity at optimal soil moisture although many of these plants were infected by F. moniliforme. Stalk and root rot developed in the majority of stressed plants grown in soil initially uninfested but contaminated by F. moniliforme after planting.
