Abstract

Concerns have been expressed by insecticide management experts and various stakeholders about the proper choice and use of insecticides by farmers in horticultural production in Ghana. This study investigated the farmers current insecticide use patterns, activities and practices of farmers that lead to occupational exposure to insecticides. Well-structured questionnaires were administered to gather relevant information on the current use pattern of insecticides, the activities and practices of farmers that led to insecticides occupational exposure and farmers’ perception of insecticides. The survey revealed that horticultural farmers relied heavily on the use of synthetic insecticides for insect pest control. These insecticides were applied frequently in various formulations and combinations, at different application rates and at short intervals ignoring the pre-entry and pre-harvest intervals. Most farmers in the survey area believed that the oral route of exposure was the most dangerous and therefore did not adequately protect themselves against the contact and inhalation routes. A health education program taking into account farmers’ beliefs and perceptions about insecticides which is aimed at promoting greater awareness about the handling of pesticides among farmers and labourers about insecticides is highly needed.
