SUMMARY Delaying the sowing of irrigated field beans in the Sudan after October greatly lowered the yield of seed, and increased both infestation by aphids and the incidence of Sudanese broad bean mosaic virus (SBBMV). Yield per plant was positively correlated with number of pods, but negatively with percentage infection with SBBMV. In greenhouse conditions, SBBMV was readily acquired from diseased plants and inoculated to healthy plants in 5 min feeding periods by both Aphis craccivora and Acyrthosiphon sesbaniae.
