Abstract

Market gardeners heavily rely on pesticides to combat pests and diseases, often neglecting health and environmental safeguards. This study examined farmers' perceptions of current phytosanitary practices and identified potential risks in the eastern oasis of Niger. The methodology included an inventory of pesticides used on crops and socioeconomic surveys of 118 market gardeners across eight oases. Results identified 19 different pesticides frequently used, with 68% unregistered. The survey revealed that 25.5% of participants applied pesticides more than 25 times to eradicate pests, and 49.77% were unaware of the required interval between the last treatment and harvest. Additionally, 39.13% of respondents repurposed empty pesticide containers at home instead of properly disposing of them. Findings indicated that 88.89% of market gardeners were illiterate, and 97.37% lacked adequate phytosanitary training, leading to improper practices. Consequently, there is a critical need for awareness programs and training to promote the safe and effective use of pesticides, thereby reducing environmental and health risks.

Key words: Market gardening, pesticides, environment, health safety, oasis, Niger.
