Book Chapter 1989

Autor: Allen, David J. Dessert, M. Trutmann, P. Voss, J.

Beans are grown in Africa in a wide range of environments, mainly in the cool highlands of central and tropical eastern Africa, leading to a diversity of cropping systems and agronomic constraints to production. Beans are cultivated for large-scale production or home consumption either in monocul...

El frijol se cultiva en Africa en un amplio rango de ambientes, principalmente en las areas montanosas templadas de las regiones central y oriental tropical de Africa, lo cual supone diversos sistemas de cultivo y limitaciones agronomicas a la produccion. El frijol se cultiva para produccion en g...

The effect of seed selection methods and removal of diseased seedlings and leaves on bean disease development and yield was studied. The best results were obtained with the removal of diseased leaves, and the combined use of diseased seedling removal plus removal of diseased leaves significantly ...

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...

Best sources of resistance in the Great Lakes Region were evaluated for stability of resistance and multi-disease resistance at four locations in Burundi, Rwanda and Zaire. Some anthracnose, Angular leaf spot and sources were found resistant at all sites. Correlation analysis also suggest pathoge...

Autor: Trutmann, P.

A review is presented on disease development in bean var. mixtures and in pure stands, the effect on diseases of adding resistance components to susceptible mixtures, and the potential on nongenetic methods to control diseases in mixtures. Four mechanisms seem to reduce disease incidence in var. ...

The effectiveness of supplementing local bean (Phaseolus vulgaris) mixtures with varieties resistant to angular leaf spot, caused by Phaeoisariopsis griseola, was evaluated in the Great Lakes region of Africa. The severity of angular leaf spot was lower (P = 0.05) in farmer mixtures supplemented ...
