AbstractThis study was carried out to evaluate the efficacy of different concentrations of acetic acid on the growth of Rhizoctonia solani , the causal agent of root rot and stem canker on broadbean. Result showed that the addition of acetic acid to the culture medium PDA at rate of 1,2,3,4 and 5%, inhibited the fungus growth by 100% . The dipping of broadbean seeds in 10 and 20% of acetic acid increased seeding emmergence by 24% compared with untreated seed. Seeds treated with acetic acid at 4,5% and fungicide Beltanol at 3ml/ l caused a reduction in infection percentage by R. solani of 39, 31and 18% respectively compared to 79% with treat meant of fungus alone.
