Pests and diseases are important production constraints of snap beans in tropical and subtropical regions of the world. Among the most important conditions favoring their development are climate, planting susceptible varieties in monoculture over entire regions, staggered planting dates, and plan...

The International Livestock Research Institute (ILRI) conducts research on strategic issues that constrain livestock productivity of resource-poor households, with a focus as smallholder crop-livestock systems. The institute conducts research in the areas of ruminant genetics, ruminant health, fe...

An outbreak of the viral zoonotic disease Rift Valley fever in East Africa in 2006/07 left more than 300 people dead and caused economic losses in Kenya alone estimated to exceed USD 30 million. Participatory studies undertaken shortly after the outbreaks abated enabled valuable lessons to be lea...

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...

The different alternatives for disease control in cassava, reported as efficient and that could be taken into account when designing technological packages for cassava production, are summarized. These are cultu-ral control (crop rotation, planting on furrows, elimination of crop resi-dues, dista...

A framework for the impact assessment of disease control strategies for Newcastle disease (ND) is discussed. This includes linking epidemiological and economic data to predict the relative impact of different control interventions at different levels from farm to region. Epidemiological transmis...
