This paper examines the origins and impact of rapid recent growth of herbicide use in Mali. Primary data come from interviews with herbicide importers and distributors and from a 2014/2015 survey of farm households in Mali’s Sudanian Savanna zone. Results suggest that a series of major supply-side changes are driving growth in Mali’s herbicide markets, most conspicuously a proliferation in the number of sellers and herbicide brands marketed, a shift to low-cost suppliers in China and India, and consequently falling herbicide prices. At the farm level, herbicides cost on average 50 per cent less than hiring weeding labor. Despite low econometric estimates of damage abatement, herbicide adoption rates reach 25 per cent in remote rural zones and 75 per cent in more accessible rural areas. Key factors affecting adoption include spatial variation in herbicide prices and rural wage rates. At current levels, herbicide use reduces peak season rural labor demand by roughly 14 per cent.Cette étude examine l’augmentation rapide de l’utilisation des herbicides au Mali, ses origines et son impact. Les données primaires utilisées dans l’étude proviennent des entretiens auprès des importateurs et distributeurs d’herbicide, et aussi d’une enquête en 2014-2015 auprès des ménages agricoles dans la zone Malienne du Savannah Soudanien. Les résultats indiquent que la croissance du marché des herbicides au Mali est dû à des changements dans l’offre des herbicides, en particulier à une prolifération du nombre de vendeurs et des marques disponibles, au déplacement des sources de herbicides a des fournisseurs bas coût en Inde et en Chine, et à une conséquente chute des prix des herbicides. Au niveau des fermes, l’utilisation des herbicides implique des couts 50% inferieurs à ceux assumés en embauchant des travailleurs pour désherber. En dépit des faibles réductions de dégâts, estimés économétriquement, l’adoption des herbicides touche le 25% dans les zones rurales les plus éloignées, et le 75% dans les zones rurales plus accessibles. Les facteurs-clé affectant l’adoption des herbicides comprennent la variation spatiale du prix des herbicides, et les salaires ruraux. Au niveau actuel des prix et des salaires, l’utilisation des herbicides réduit la demande de travail agricole d’un 20% pendant la haute saison horticole.

Highlights • The first sorghum hybrids based on local germplasm in West Africa yield well on farms.• Intrahousehold status on extended family farms affects adoption of improved seed.• Adoption raises yield, reduces the harvest share consumed and also purchased.• Adoption increases the harvest share sold and dietary diversity.

ABSTRACT This article examines the structure of the Malian fertiliser value chain and its performance in the context of the national subsidy programme, drawing on a review of the literature, farm household survey, and interviews with fertiliser suppliers. It finds that participants in the subsidy programme use more fertiliser and have significantly higher yields. The number of wholesalers and retailers has risen, but procurement remains concentrated. Poor fertiliser quality is a recurrent problem. The high cost of the programme raises questions regarding its sustainability. Mixed performance reflects the need for better monitoring and evaluation, and transparency in the programme.
