Pathogenicity of bean pathogenic Pythium spp. on major crops in a bean based cropping system

In South Western Uganda, Pythium spp. cause severe bean root rots resulting in yield loses of up to 100%. Despite concerted efforts in control of the disease, the root rot problem continues to increase. The cause of increased epidemics is not known, although an impact of farming systems is suspected...

Description
Summary:In South Western Uganda, Pythium spp. cause severe bean root rots resulting in yield loses of up to 100%. Despite concerted efforts in control of the disease, the root rot problem continues to increase. The cause of increased epidemics is not known, although an impact of farming systems is suspected. The study involved surveys in Kabale district to establish the incidence and prevalence of root rots on other crops in a bean based cropping system. Screen house studies were initiated to study the effect of bean pathogenic Pythium spp. It was found that this pathogen does have a significant effect on maize, millet, peas and sorghum Sorghum is affected most while maize is least affected. This research will contribute to a better understanding of bean root rot in the region as well as in the development of recommendations on which crops to use as intercrops of beans so as to control the root rot problem in the region.
