Opportunities for Expansion of Push-Pull Technology As an Agroecological and Sustainable Intensification Approach in Africa

The push-pull technology (PPT) has often been presented as a management strategy for stemborers and witchweed. However, its value as an agronomic practice and an agroecological approach remains largely underappreciated. This review aims to appraise the PPT used in eastern Africa, synthesize evidence for its ecological and economic benefits, and identify barriers to its adoption and opportunities for its expansion to other crops and farming systems in sub-Saharan Africa.
