Adoption of Integrated Pest Management in Ghanaian Tomato Agriculture: What Are the Key Determinants?

Résumé

Integrated pest management (IPM) offers an effective and environmentally sensitive approach to pest control, reducing reliance on chemical pesticides. However, its adoption among tomato farmers has been slow, with excessive chemical pesticides causing resistance, environmental pollution, and biodiversity loss. This study examines the factors influencing IPM adoption among tomato farmers in Offinso North, Ghana. Data were collected from 388 farmers using a structured questionnaire. Results indicated that access to extension services, farming experience, the number of workers, and years of formal education significantly influenced the adoption of various IPM methods. Access to extension services was critical across all methods, while farming experience and the number of workers were key for cultural and mechanical practices. Education enhanced the adoption of mechanical techniques. These findings highlight the importance of targeted training programs and access to resources to improve IPM knowledge and adoption among farmers. Policymakers should focus on farmer education and extension services to enhance sustainable pest management by providing technical support, facilitating access to IPM inputs such as organic fertilisers and biological control agents, and guidance in implementation. Other interventions may include enhancing farmer groups' access to low-interest finance or credit facilities.
