Vegetable production in Togo is seriously affected by pests attack. To reduce damage, farmers indiscriminately use pesticides. Various studies have reported high concentrations of pesticide residues more than acceptable limits in vegetables and other edible food. The aim of the presented study is to study the attitudes and practices developed by vegetable growers about pesticides applications. A standardized questionnaires which included socio-professional factors, provisions and operations concerning the use of varieties of pesticides were addressed to 150 growers in vegetable farms along the Littoral of Togo. In order to complete data concerning pesticides, seven runoff private companies and agents of the ‘Direction de la Protection des Végétaux’ were interviewed. Data were statistical treated using Sphinx Plus. The survey showed that vegetable growers have an acceptable educational level (36% have more than 7 years of formal education) to exploit instructions concerning pesticide use, but more than 97% do not use recommended tools. Only 21% of them received training for pesticide use. Moreover, 84% of them did not usually wear gloves, and less than 30% used oro-nasal masks. Failure to observe minimum intervals between pesticide application and sale is worrying because extremely hazardous (Carbofuran and Cadusaphos) or moderately toxic (Cypermethrin, Dimethoate, Endosulfan, Chlorpyrifos-ethyl, Fipronil) are the products currently used. The presented study indicates that pesticides application in the survey area represents a potential risk for the environment, farmers and consumers. More investigations are needed to quantify pesticides residues on the vegetables currently con,umed and moreover, to determine the potential effect of those products on human and animals health.
