Figure 1. Seasonal prevalence (a) and incidence (b) of Pythium, Fusarium, Sclerotium and Rhizoctonia root rots in Ugandan common bean agroecologies across three seasons (2013A, 2013B and 2014A) between March 2013 and June 2014. For each root rot type, bars followed by different letters are significantly different (p ≤ 0.05, Tukey’s Studentized range test).
