eports of cassava root rot disease from different African countries have increased in recent times. Field studies were conducted from July 1998 to October 1999 to determine a reproducible disease assessment method that would allow the comparison of results from different locations and an evaluati...

This project aims at: (1) identifying the major pathogens of the bean root rot complex, (2) screening for resistant germplasm, and (3) evaluating low-input control methods that will significantly decrease economic losses caused by root rots in the main bean producing regions of Peru, Ecuador, and...

El presente proyecto tiene por objetivos: 1) identificar los principales patogenos asociados con el complejo de pudriciones radicales del frijol; 2) seleccionar germoplasma resistente; y 3) evaluar metodos de control de bajo costo que permitan disminuir significativamente las perdidas economicas ...

Pythium spp, cause severe bean root rots under cool and humid conditions. Poor soils and intensive cultivation compound the epidemics. There are more than 120 species reported globally some of which are very pathogenic meanwhile others are saprophytic. Yield losses due to Pythium outbreaks can be...

Root rot severely constrains bean (Phaseolus vulgaris L.) production in parts of Western Kenya. Genetic and soil management options were evaluated for an integrated root rot management approach. Four hundred genotypes were progressively screened in the field for resistance to root not over six se...

Objective: In Southwestern Uganda, bean root rot epidemics associated with Pythium species are frequent despite the use of various management methods. This study set out to determine whether other crops in bean cropping systems of Southwestern Uganda are affected by Pythium root rots and to chara...

Several chemicals were tested at both the on-farm and exptl. levels to control major seed-transmitted root diseases in the Great Lakes region of Africa. Seed treatments to control the beanfly in Burundi were combined to assess the efficiency of combined treatments against fungi and insects. Indiv...
