This is one of 280 summaries describing key outputs from the projects
run by DFID's 10-year Renewable Natural Resources Research Strategy
Summary for Project titles: R8449: Promotion and dissemination of
integrated pest and soil fertility management strategies to combat
striga, stemborers and declining soil fertility in the Lake Victoria
basin and R8412: Decision support frameworks for weed management in
lowland rice in Bangladesh.
'Push-pull' pest management means growing plants that repel pests
together with those that attract and kill them. One of these
partnerships, Napier grass and the legume Desmodium, prevent stemborer
and witchweed in maize. These push-pull partners are also good fodder
crops and improve soil fertility. Other integrated pest and soil
management strategies proven in Kenya, Uganda, Tanzania, Malawi,
Ethiopia and Nigeria are now available for small farmers to improve
mixed maize-livestock systems—crop rotation, intercropping, manure and
fertilizer, dual-purpose grain legumes and resistant varieties. Over
6000 smallholders in Kenya and Tanzania already use environmentally
friendly push-pull methods to control witchweed and stemborer, improve
soils, and grow more fodder for livestock. These technologies have great
potential for other cereals, particularly sorghum and millet.
