Effect of plant growth regulators on white mould (Sclerotinia sclerotiorum) on bean and cucumber
Journal of Phytopathology - Phytopathologische Zeitschrift 150 (8-9), 481-487
Abstract: The effect of plant growth regulators on the pathogenic fungus Sclerotinia sclerotiorum (white mould) was investigated under in vitro and in vivo conditions. Naphthalene acetic acid inhibits the fungus in vitro and in vivo. It reduced white mould disease severity on bean and cucumber plants at concentrations of 200-400 µg/ml. Gibberellic acid (GA₃) promoted both mycelium and white mould disease severity on plants at concentrations of 50-250 µg/ml. Methyl jasmonate (MeJa), and abscisic acid (ABA) decreased mycelium growth of S. sclerotiorum in vitro. MeJa decreased bean and cucumber white mould disease at concentrations of 75-250 µg/ml.ABA increased disease development on bean and cucumber plants at concentrations of 100-300 µg/ml.
