Fusarium moniliforme and F. roseum were isolated from the diseased seedpieces of sugarcane plants. Various methods were employed to inoculate canes with the different isolates, i.e., seedpiece-dipping, addition of inoculum to the substrate, and stem-puncture. F. moniliforme reduced germination of variety P.O.J. 2878 as much as 40 percent when seedpiece-dipping and substrate infection methods were used. Inoculation with F. roseum had little effect. Sugarcane varieties P.O.J. 2878, P.R. 1117, P.R, 980, P.R. 1059, P.R. 1085 and N: Co. 310 proved susceptible in varying degrees when inoculated with F. moniliforme by the stem-puncture method. Among the chemicals tested, Benlate, a systemic fungicide, seemed to be most promising for protecting sugarcane seedpieces against Fusarium rot.
