In bio-assay tests ether extracts of the roots and of the stalks of both resistant and susceptible corn inbreds inhibited the growth of Fusarium moniliforme Sheld. and Gibberella zeae (Schw.) Petch, the level of inhibition varying over the season. However, the extracts of the resistant and susceptible inbreds did not differ consistently in their ability to inhibit fungus growth on any given date. Thus, this bio-assay method cannot be used to evaluate inbreds for resistance to root and stalk rot.
