This research aims to characterize and establish a typology of garden farmers according to their knowledge and use of biopesticides. The study was conducted in Louda, a village in the commune of Boussouma in the North Central region of Burkina Faso. A semi-structured socio-economic survey was conducted among 20 garden farmers, equally divided between men and women. The results of the survey showed that 70% of the garden farmers cited caterpillar as the major pest and leaf curl as the major disease. Twenty-five (25) % and 15% of the garden farmers use biopesticides as a phytosanitary treatment against caterpillar and leaf curl respectively. Unregistered industrial synthetic chemical pesticides for other crops are often used by garden farmers. Ignorance or not of the existence of biopesticides and their use against crop pests are the main criteria that establish the typology of garden farmers in Louda. Age, sex, instruction, mode of access to land, family size, number of salaried agricultural workers and average annual income of the garden farmers are the socio-economic parameters that discriminate this typology. This typology is therefore associated with the socio-economic characteristics of garden farmers.
