Chitosan was effective in inhibiting radial growth and sporogensis of F. oxysporum. f. sp. ylcopersici in vitro. The inhibiting activity of chitosan was increased when its concentration increased. Light microscope observations showed that chitosan at concentration greater than 0.1 mg/mL induced morp...

Resistance to early blight of the tomato plants was induced by chitosan (1 mg/mL) at the fourth-leaf stage of seedlings. Chitosan treatment of tomato leaves before inoculation reduced the rates of diseased leaf and disease index. The relative efficiencies of resistance in cultivars were Hezuo908(hig...
