An evaluation of smallholder farmers' knowledge, perceptions, choices and gender perspectives in vegetable pests and diseases control practices in the humid tropics of Cameroon

摘要

The use of pesticides on vegetables in Sub-Saharan Africa by small-scale farmers dates back to several decades. However, little research has been conducted to capture farmers' perception on pesticide use on vegetables. This study aims to identify and evaluate farmers' local knowledge and perception of vegetable pests and diseases and their protection and management practices in humid tropics of Cameroon. Key informant and focus group interviews complemented with quantitative one-on-one structured interviews of 130 farm households and observational assessments were employed. Standard vegetables such as chili pepper are the preferred vegetables in Bafoussam area, whereas traditional vegetables dominate in the Buea and Ebolowa area. Among over 15 vegetables, more than 60% are in the traditional African vegetables category, with insect infestation and fungal infection known to be the most critical biotic production constraints. Successful intensification and diversification of cocoa-based systems with vegetables will require increasing awareness on safer production methods, long-term harmful effects of pesticide misuse, and strengthening the capacity of regulatory agencies responsible for preventing importation of banned pesticides.
