| Abstract | ||||
| Some abiotic treatments effectively induced resistance in faba bean (cv. Giza 3) against chocolate spot disease when were applied as seed soaking or foliar spray. The compounds were di-potassium hydrogen phosphate, ferric chloride, salicylic acid and ethephon. Application of chemical treatments as seed soaking or foliar spray reduced the percentage of browning and spreading of Batrytis lesion using detached leaves technique. Foliar spray of faba bean plants with K2HPO. and FeCI3 at concentrations of 50 mM and 20 mM, respectively, Significantly reduced chocolate spot under field conditions. Meanwhile, seed soaking was less effective. Application of K2HPO. and FeCI3 significantly reduced flower drops and increased seed yield. SDS- PAGE of protein revealed incidence of various new bands in treated plants. | ||||
