Abstract

This study aimed to value the environmentally friendly pest management options of vegetable farmers. Over the past decades, attempts to reduce the misuse and overuse of synthetic pesticides in Thailand have been met with limited success. One of the main reasons was that the proposed pest management campaigns were not in accordance with the farmers’ preferences. Data of 303 vegetable households were collected from 3 provinces in the vicinity of Bangkok (Ratchaburi, Nakorn Pathom, and Pathum Thani provinces). Discrete choice experiment was employed to assess farmers’ preferences. Results showed that sampled farmers highly valued the health and environmental effects of the proposed program. Moreover the training on Integrated Pest Management (IPM) and Eco-vegetable logo were the preferred choices. Therefore, government should support and allocate budgets on environmentally friendly pest management program to benefit the long-term health and environment. In addition, government should invest in IPM training programs and should consider the possibility of endorsement of eco-vegetable logo in the future.
