The parasitical pressure in the market gardening, hugely affects the quality and quantity of vegetables production. To cope with that problem, the farmers use several pesticides varieties, which could have on one hand some consequences on the environment, and on the other hand on the heath of farmer and those of the consumers. To ensure a lasting production by following good practice, an analysis of phytosanitary practice has been performed in Korhogo (northern of Côte d’Ivoire), which is the greatest production zone of market garden crops. The said study was conducted through a survey done in 5 sites of market garden crop production in above mentioned locality according to 20 farmers per site. At the end of that evaluation we noticed that the most produced plants are cabbage, sorrel of guinea, eggplant, lettuces, okra, and chilli pepper. The study also showed that the most part of the used pesticide in the different sites were not appropriated for market garden plants since they were recommended for cotton crop. In addition there was not relationship between the multiple usages of pesticides and the diversity of vegetable growth plants and/or market garden crop yield. Finally, the present study sustained the possibility of a good phytosanitary practice (selective phytosanitary practice) in market gardening including diverse vegetable plants varieties.
