Title: Anthracnose Disease in Common Bean (Phaseolus vulgaris L.) in Shambat, Sudan II. Disease Incidence, Severity and Effect on Yield
Author: Mustafa El Balla
Abstract: A field experiment was conducted for two seasons (1999/2000 and 2000/2001), at Shambat Research Station, to investigate the effect of anthracnose disease incited by Colletotrichum lindemuthianum (Sacc. and Magn.) Bri. and Cavi. in three common bean (Phaseolus vulgaris L.) cultivars. Mean disease incidence of 15.70% was recorded in 1999/2000 season and 13.79% in 2000/2001. Mean disease severity of 0.39 and 0.47 were recorded in seasons 1999/2000 and 2000/2001, respectively. Mean pod infection in season 1999/2000 was 19.59% and mean seed infection in the same season was 15.77%. The corresponding results for season 2000/2001 were 49.62% and 20.98%, respectively. Mean seed weigh reduction was 24.72% in season 1999/2000 and 26.33% in season 2000/2001. The introduced cultivar Cranberry out-yielded the two local cultivars in both seasons. The increase in mean yield was 21.13% in season 1999/2000 and 54.04% in season 2000/2001.
