The present work was undertaken to investigate the possible role displayed by some phenolic compounds such as shikimic and salicylic acids or their combination in regulating growth, metabolism and productivity of faba bean plants infected by Botrytis fabae. In vitro, phenolic compounds inhibited mycelial growth of B. fabae. A pot experiment was conducted to evaluate the beneficial effect of seed presoaking in phenolic compounds on faba bean plants (Giza 429) as alternatives to fungicide to increase faba bean resistance against chocolate spot disease. Treatment of infected faba bean with...
