A field experiment was conducted at the main research station of the International Center for Agricultural Research in the Dry Areas (ICARDA) at Tel Hadya, Syria in 1983/84 season. Application of pirimicarb (Pirimor) 50% wp at a rate of 0.5% (10 g/20 l water) at early pod setting stage of faba beans decreased the black bean aphid population and increased seed yield. Aphid infestation had a significant effect on plant hight, number of pods/plant, and number of seeds/pod. No significant differences in yield were found between plots sprayed early and late, but the yield of sprayed plots was significantly higher than that of the unsprayed check
