The Cassava Weed Management Project (CWMP), funded by the Bill and Melinda Gates Foundation (BMGF) from 2013-2018, aimed to promote the use of safe and environmentally friendly herbicides for effective weed control in cassava production in Nigeria. This retrospective evaluation, conducted by a consortium of experts from the International Food Policy Research Institute (IFPRI) and Sahel Consulting Agriculture and Nutrition Limited, examined the extent to which the private sector has scaled up the herbicides tested and recommended by the CWMP, as well as the factors influencing companies' decisions to register and deploy these products. The evaluation, conducted in 2023-2024, employed a mixed-methods approach that relied heavily on the qualitative approaches to uncover underlying factors affecting scaling and adoption. The methods included document reviews, key informant interviews (KII), focus group discussions (FGD) with cassava farmers, mystery shopper surveys of agro-dealer shops, and quantitative analysis of secondary data from sources like official company data and the Living Standard Measurement Study – Integrated Survey on Agriculture (LSMS-ISA).
