CABI, in collaboration with international experts and organizations such as the University of Neuchâtel, icipe, Dudutech, and the Rwanda Agriculture and Animal Resource Development Board, is spearheading a project to develop nematode-based biocontrol solutions aimed at combating the fall armyworm (Spodoptera frugiperda) in Africa. This pest poses a significant threat to crops, especially maize, across the continent. Funded by the Swiss National Science Foundation (SNSF) and the Swiss Development Cooperation (SDC), and part of the PlantwisePlus programme, the initiative seeks to offer a safer, environmentally friendly alternative to chemical pesticides through the use of entomopathogenic nematodes. The project not only focuses on creating effective application techniques for these biocontrol agents within an Integrated Pest Management (IPM) plan but also emphasizes capacity building among young scientists, agricultural extension officers, and farmers. This approach aims to enhance food security by reducing reliance on harmful pesticides and addressing the continuous pest multiplication challenge, especially in regions like Rwanda where maize is grown year-round.
