AbstractThe study conducted to evaluate the systemic resistance of bean seedlings infected with root rot caused by Rhizoctonia solani using nutritional element of copper and Saliycili acid showed that copper is effective in the reduction of the mycelial growth of the fungus that inhibited by (10.5%) when used at 4 mg/ltr. The results also provide the effectiveness of Salicylic acid in the reduction of growth rate of the fungus since inhibited by 56.7% when used in the at 400 mg/l However copper and salicylic acid led to the reduction of infection severity with Rhizoctonial root rot which reached 0.54 and 0.51, respectively .
