OSU Greenhouse Operations Integrated Pest Management Program April 2009
The IPM strategy for the OSU greenhouses is to apply a comprehensive approach to solving pest problems within the facility. Primary to this mission is to instill a sense of community and promote effective communication between users and staff. This plan considers all options of pest management to prevent damage to research projects by insects, mites, diseases, weeds, cultural practices, and environmental conditions for a predetermined injury level or threshold. The pest controls chosen strive to minimize the risks to human health, the environment, and non-target organisms.
IPM Techniques for greenhouse users
- Communication – Open dialogue can reduce problems and pesticide use within the facility. Notify Greenhouse Operations staff of research projects involving the use of insects and diseases.
- Knowledge of the plant & pest biology – development of a cultural and organizational plan for specific crops will enhance the ability to control pest and diseases.
- Pest prevention – sanitation through out facility: no weeds in pots or on floors, clean and/or disinfected tools, walkways, and bench tops. Cultural practices: closing doors, healthy plant material, prompt disposal of plant material, autoclaves, pot pasteurization, screening if possible, resistant mother stock, people and plant movement, and annual greenhouse furlough of plant material.
- Monitoring - weekly scouting, recorded results, plant & people movement, communication with users; pest inspections, indicator plants, sticky cards, and plant health issues which contribute to pest stress.
- Diagnosing problems – reference materials at greenhouse office, plant clinic, project goals and needs vs. facility needs and goals.
- Thresholds – predetermine with users, establish when to treat problems, affect on other projects, and update greenhouse operations as levels change.
- Control measures - Chemical control: timing with pest and plant life cycles, equipment choice, trained licensed applicators, records kept at greenhouse office. Pesticide selection includes, labeled for greenhouse use, compliance with label directions, avoidance of broad spectrum and danger labeled chemicals. Biological control: used when practical, economic considerations, user cooperation and with implementation essential.
