Utilisation et gestion des pesticides en cultures maraîchères : cas de la zone de Nkolo dans la province du Kongo Central, République démocratique du Congo

Abstract

Objectives: Pesticides are systematically applied in vegetable crops at Nkolo (in Kongo Central province in the western DR Congo) in order to provide crop protection and improve the yield. This study aimed at assessing the knowledges and practices of gardeners in relation to of pesticides use. Methodology and Results : Forty-six gardeners were interviewed. The questionnaire focused on the pesticides types, solution procedures, application rate and frequency, gardener protective equipment, and the pre-harvest intervals. Socio-professional traits of gardeners were also recorded. Majority of gardeners was male (93% vs 7% of women). Pesticides, especially fungicides and insecticides are systematically applied, based on preventive application and generally in 7 (dry season) and 14 (rain season) days of intervals. Depending on the gardener, 1 to 9 pesticides are used per crop cycle. All the pesticides are generally mixed and applied together on the crops using a manual sprayer. Application rate and pre-harvest intervals varied with gardeners. Most of them do not have been trained on pesticide use (83%), do not use protective equipment (72%) and abandon pesticide containers in the field (46%). Conclusion and application of results : Gardeners in Nkolo and surroundings have poor knowledges on pesticides use and do not use it properly. Systematically application of pesticides without proper protective equipment result in regular contact of gardener with pesticides and exposes them to pesticide poisoning. Furthermore, improper pesticides use should increase the risk of pest resistance in the long term use. In order to mitigate the risk of poisoning for gardeners and consumers, and environmental pollution in Nkolo and surroundings, there is an urgent need to promote proper use of pesticides.

Knowledge, attitudes and practices of market gardeners toward pesticide use in Bamako, Mali

“…In this study, all the market gardeners were male. This result is similar to that found by two other studies, which found 93.47% and 98.3%, respectively [8,9]. This high proportion of men could be explained by the fact that market gardening is an activity purely dedicated to men.…”

Les risques sanitaires lies a l’utilisation des pesticides dans les bas-fonds rizicoles de la commune de dano, Province du Ioba Burkina Faso

“…A cause de l'insuffisance de la protection lors des traitements, les producteurs ont été plus victimes d'intoxications directes (par inhalation, par contact cutané ou oculaire) avec les pesticides (90%). Ces résultats corroborent avec les résultats de Muliele et al (2017) et Ngameni Tchamadeu et al (2017 sur les risques sanitaires encourus par les producteurs en raison des mauvaises conditions de gestion des pesticides.…”
