Fig. 3. Phytotoxic effect and disease suppression by FNX-100 applied as foliar spray (F) and soil drench (D) at various concentrations (foliar: 1.0, 2.0, 3.0%; drench: 0.5, 1.0, 2.0%). Disease severity was assessed on an ordinal 0 to 4 scale: 0 = no disease; 1 = presence of stem lesion or girdling; 2 = stem lesion or girdling plus wilting of leaves adjacent to the lesion; 3 = stem lesion or girdling plus wilting of the lower and upper leaves; 4 = dead. Phytotoxicity was assessed based on an ordinal scale: 0 = no damage; 1 = small chlorotic lesions or tip/edge burn; 2 = few leaves w/large burn areas; 3 = more leaves with large burn areas; 4 = all leaves burned and plant wilting; 5 = plant dead.
