Abstract
Through the use three concentrations of salicylic acid 300 , 400 and 500 ppm and during two periods of the immersion 30 and 60 minutes to induce resistance against disease alternaria leave spot caused by fungus Alternaria alternata. It is clear that the seed treatment of faba beans with 500 ppm of salicylic acid for a period of immersion 60 minutes gave the highest height of the plants reached 45.64 cm. of the triple interference between periods of immersion and concentration and readings note that the use of acid concentration of 500 ppm for 60 minutes gave the highest height of the plants at the second reading and reached 60.59 cm and the same concentration is better with a immersion 60 minutes led to a reduction of the disease severity and reached to 0.17 and did not significantly different from the 30-minute immersion period for the same concentration,while the disease severity in control treatment was 0.67. This result suggests the possibility of using salicylic acid to induce resistance to alternarial leave spot instead of using chemical pes- ticides.
