This article is part of the promotion of agricultural extension and advisory services by private actors. The objective is to analyse the potential of agricultural input distributors in terms of agricultural extension and advice. Data was collected in the town of Dschang from 22 input distributors, 65 farmers who are their clients, and 03 staff members of the departmental delegation of the Ministry of Agriculture and Rural Development of Menoua. Data from the questionnaire were analysed using SPSS (Statistical Package for the Social Sciences) version 22.0 and Excel 2013, and those from the interview guide were transcribed and thematically analysed. The input distributors emerged in a context of state disengagement from services previously offered to farmers and post-crisis liberalisation in the 1980s. Most of them are women (59.1%) who own or manage shops owned by their husbands. Most of these input sellers (47.62%) are between 25 and 35 years old, with a higher educational level (40.9%) and sometimes have training related to agriculture. The clientele of these agricultural input shops is mostly made up of small individual farmers (95.4%). These input shops offer various extension and advisory services to their customers. These services include among others: the provision of inputs in return for payment, technical and practical advice on the use of inputs, monitoring and support for customers in their agricultural production activities, and information on innovations in the field of inputs. Through these services offered to farmers, input shops play the role of extension workers and agricultural advisors and are also an undeniable source of information. For almost all farmers surveyed (99%), input distributors are their main source of agricultural advice and information. The provision of these services by input dealers contributes to improved agricultural yields and increased incomes for the farmers who benefit from them. For 90.8% of the farmers surveyed, their standard of living has increased thanks to the services provided by input dealers. Input distributors need to be reconsidered as full-fledged actors in the agricultural extension and advisory system and be supported to play this role effectively and efficiently. The overall performance of the agricultural extension and advisory system depends on it.
