摘要

Vegetable production in West Africa is increasingly threatened by the resurgence of leafhopper Amrasca biguttula Ishida, a major pest responsible for severe yield losses. To maintain crop productivity, vegetable growers frequently rely on chemical pesticides, a practice that raises serious concerns regarding human health and environmental safety. This study aimed to assess phytosanitary practices used for the management of A. biguttula through a survey of market gardeners in urban and peri-urban areas of Ouagadougou, Burkina Faso. The study was conducted at four major vegetable production areas. Survey results showed that all the market gardeners were well aware of A. biguttula and reported its presence on their crops. The results indicated that a significant majority (84%) use synthetic insecticides compared to 16% who use biopesticides (P < 0.001). Regarding pest management intensity 65% of respondents reported applying pesticide treatments three times per week. The results showed that 60% of chemical products used by the growers were not registered by the Sahelian Pesticides Committee (SPC). Respiratory difficulty, headache, cold, and cough are frequently cited by gardeners as various health disorders following exposure to pesticides. The results highlighted that the level of education influences both perception and the use of personal protective equipment (PPE). These findings highlight the need to strengthen regulatory enforcement and institutional support for improved pesticide management in peri-urban vegetable production. Enhancing growers training, improving pesticide market regulation, and promoting access to effective biopesticides and agroecological practices could reduce reliance on synthetic pesticides.
