This study was conducted in order to find out the available safe methods to control this disease. The obtained results could by summarized as following: 1- Paulista bean cultivar showed the highly susceptible to rust disease fungus both in 2018 and 2019 growing seasons where the average severity of infection recorded 82% at 2018 growing season. 2- Nebraska bean cultivar was the least susceptible one to the disease which resulted 42.3% as average of infection severity in 2018 growing season. 3- Similar results were obtained also in 2019 growing season.
