Author(s): Negash Hailu* and Hailu Tontosha
Common bacterial blight (CBB) caused by the bacterium Xanthomonas campestris pv. phaseoli is a major disease of
common bean affecting its production in southern Ethiopia. This study was conducted to determine the effect of
variety, seed treatment and foliar spraying frequencies of bactericide on disease severity, yield and yield components
of common bean. Field research was conducted at Hawassa agricultural research center during 2017/18 main
cropping season using Hawassa dumme and Mexican-142 varieties. Streptomycin seed treatment was integrated with
Kocide-101 foliar spraying frequency at the rate of 2.31 kg ha-1 at two, three and four week’s intervals. The design
was randomized complete block design arranged in factorial with three replications. Due to the effect of variety,
severity was reduced by 17.2% and the mean seed yield .. View more»
