Abstract
Ethephon treatment proved efficient in inducing resistance of faba bean plants against both chocolate spot (Botrytis fabae Sard.) and rust (Uromyces viciae fabae (Pers.) de Bary). Seed Soaking in 800 pg/ml showed a significant reduction in severity of both diseases and a notice­able increase in yield of seeds/plant. The same treatment caused a pro­nounced reduction in percentage of browning and spreading of choco­late spot beneath inoculum .droplets placed on the abaxial surface of detached leaves. However, treatment with 1000 pg/mi led to lower lev­els of both diseases. Treatments with 600 and 800 pg/ml of ethephon showed an increase in phytoalexin accumulation in leaf tissues after 24 h of elicitation by each of B. fabae or B. cinerea.
