Biocontrol efficacy of the six <i>Fusarium oxysporum</i> isolates shown to be nonpathogenic to cucumber^a.

aThe experiment was conducted in a greenhouse (18-28°C) using the substrate infestation inoculation method.
bPlants of each treatment were assayed on a scale of 0-4∶0 =  Healthy plants, 1 =  cotyledon and first leaf with yellowing, 2 =  stunting or <1/2 leaves with yellowing, 3 =  stem yellowing, vascular discoloration, and >1/2 leaves with wilt symptoms, and 4 =  plant wilted or dead. The disease scale was converted to disease severity and rounded off, as described in the Materials and Methods.
cThe CK treatment was pre-inoculated with distilled water and then transplanted into infested soil with Foc100.
