Widespread use of highly toxic pesticides primarily for agricultural purpose has generated increasing
ใช้อย่างแพร่หลายของสารกำจัดศัตรูพืชที่เป็นพิษสูงเป็นหลักสำหรับการทำการเกษตรที่เพิ่มขึ้นได้สร้างความกังวลเกี่ยวกับผลกระทบเชิงลบของสารกำจัดศัตรูพืชที่มีต่อสุขภาพของมนุษย์และสิ่งแวดล้อม concerns about the negative impact of pesticides on human health and the environment. Integrated pest
management (IPM) usually seeks to minimize the use of pesticides and can be utilized to solve pest
problems while minimizing risks to people and the environment. A total of 220 vegetable farmers in
Nakhon Ratchasima Province of Thailand was interviewed with the objective of investigating the factors
determining their adoption or non-adoption of IPM practices. Thefindings demonstrated that farmers
had different uncompromising reasons for determining the use of IPM for their insect pest management.
Higher costs of insecticides (91%), adverse effects of insecticides on human health and the environment
(80%), and a greater risk of insect pests developing resistance to insecticides (28%) were the primary
reasons for the adoption of IPM by vegetable growers in the study area. The reasons for the rejection of
IPM practice were unsuitability of IPM for a large farm (52%), implementation difficulties (80%) and a
greater belief in synthetic insecticides and their efficacy for target pest control (39%). A comparison
between the IPM and the non-IPM farmers showed a significant difference (P<0.01) in farmers’
knowledge of pest management, which influenced IPM adoption or non-adoption. The IPM farmers had
greater knowledge about identifying natural enemies and their beneficial role in controlling insect pests,
about plant extracts and their efficacy in controlling insect pests and about sticky traps and their efficacy
in monitoring natural enemies and controlling insect pests. For example, 24% of IPM farmers had
knowledge of natural enemies whereas it was only 4% for the non-IPM farmers. A logistic regression
model wasfitted which showed that lower cost of pest management, better knowledge on IPM after
training and availability of extension services were the factors which influenced farmers’ adoption of IPM
practice. The non-IPM farmers rejected adoption of IPM due to the common belief that natural enemies
would not be effective in controlling insect pests and yields of vegetables would not be increased by
practicing IPM
