Integrated Pest Management (IPM) is well known as a pro-environmental technology in agriculture. Therefore, investigating adoption of IPM mechanisms is crucial for agricultural products such as pistachio in Iran. The main purpose of this study was to assess the role of factors affecting IPM adoption by pistachio growers in Kerman Province. Survey was the research method and it was executed using researchers-designed questionnaire. Totally, 225 pistachio growers were selected as sample size, using two-stages random cluster sampling method. Validity of the questionnaire items was entirely approved by a panel of experts. Cronbach’s alpha coefficient was used for reliability approval. Findings revealed that individual factors including age, education, farming experience, motivations, participation and innovative spirit in conjunction with economic factors such as income, and technological costs affect IPM adoption procedure. In addition, educational services along with IPM technical knowledge and environmental attitude positively changed IPM adoption. The result of structural equation modeling illustrated that education, innovative spirit, life motivation, welfare motivation, income, technological costs, educational services and IPM technical challenges can significantly predicte IPM technical knowledge by direct effects. Indeed, IPM technical knowledge promotes environmental attitude and directly improves IPM adoption. Some practical recommendations are presented based on the research findings.
