N2  - This study investigated the effect of shikimic and salicylic acids at the concentrations of 0.4 and 0.7  mM, respectively,  or their combination as phenolic compounds and Ridomil MZ at the concentration of 250 g/100 L as a fungicide on osmotic pressure (OP), solutes allocation, organic acids, inorganic ions and relative water content were quantified in  Vicia faba leaves infected by  Botrytis fabae.  Pathogen induced noticeable decrease in  osmotic pressure, total soluble sugar (TSS) and inorganic osmolytes (i.e. Na+, K+, Ca2+, Mg2+ and Cl-) while caused obvious increase inproline, total soluble nitrogen (TSN) and organic acids (i.e. Keto and citric acids) in water extract of the leaf of faba bean plants. Furthermore, pathogen caused marked decrease  in  relative  water  content  (RWC)  of  infected  leaves  and  as  a  consequence  the saturation water deficit (SWD) was increased. Exogenous application of shikimic acid, salicylic acid  or  their  combination  could  counteract  the  adverse  effects  of  B.  fabae on  osmotic adjustment  by  inducing  additional  increase  in  proline,  total  soluble  sugars,  total  soluble nitrogen and organic acids which in turn increase the osmotic pressure as well as relative water content in leaves of infected plants. Recovery of osmotic adjustment as well as leaf turgidity of infected host by using these chemical inducers may encourage the using of them as protective control means. The results of the present study showed also that the application of chemical  inducers  such  as  shikimic  and  salicylic  acids  or  their  interaction  increased  the resistance of Vicia faba against the chocolate spot disease.
