Efficacy of nonpathogenic <i>Fusarium oxysporum</i> isolates to suppress cucumber Fusarium wilt development^a.

aThe experiment was conducted in a greenhouse (25-35°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.
cAmplification by primer pair FIGS11/NPIGS-R; NA =  not applicable, - = not.
amplified, + = amplified.
