摘要:An instruction- and experience-based workshop was conducted for Oklahoma greenhouse producers to teach principles of integrated pest management (IPM) for common arthropod pests of greenhouse crops. Workshop effectiveness was evaluated using a pre- and post-test instrument to measure changes in knowledge and attitudes about IPM and current use and intention to adopt IPM practices. Findings indicate the objectives were accomplished as participants reported significant increases in IPM knowledge, a marked acceptance of IPM practices, and a willingness to adopt IPM. Extension workshops that combine classroom instruction and hands-on demonstration can be used effectively to teach relevant concepts to stakeholders.
