  2. Problem Area 5 Integrated Pest Management

  3. Lesson 7Identifying and Managing Plant Pests and Diseases in the Greenhouse

  4. Interest ApproachHow Do People Get Colds? • Drinking after others at the water fountain! • Not washing hands before eating! • Sharing a soda! • The virus comes from infected individuals

  5. Interest Approach cont.How Do We Get Diseases in the Greenhouse? • One plant drinking after another?!? • What are some ways that pests are introduced into the greenhouse?

  6. Student Objectives: • 1. Identify the major categories of pests found in the greenhouse. • 2. Discuss pest control techniques used in a greenhouse. • 3. Describe the different practices of integrated pest management used in the greenhouse.

  7. Abiotic diseases Biological pest control Biotechnology Biotic diseases Chemical pest control Cultural pest control Genetic pest control Insect Mechanical pest control Nematodes Pathogens Terms

  8. Major Categories of Pest in Greenhouses. • pest - anything that causes injury or loss to a plant • Insects • Nematodes • Weeds • Plant diseases • Animals

  9. Diseases (2 Groups) • Abiotic diseases are noninfectious or disorders. • Biotic diseases are caused by parasites or pathogens that are infectious and transmissible.

  10. Pest Control Techniques Used in Greenhouses • Cultural pest control • Biological pest control • Mechanical pest control • Chemical pest control • Genetic pest control

  11. Cultural Pest Control • Management techniques to control pests; includes proper maintenance programs, sanitation, and resistant varieties.

  12. 1. Improve the soil or media 2. Select pest-resistant plants 3. Purchase quality seeds and healthy plants 4. Use sterile growing media when potting 5. Plant at recommended times 6. Mulch plants 7. Remove dead and diseased plant foliage 8. Water at proper time 9. Use insect traps 10. Use proper pruning techniques 11. Set up physical barriers Cultural Pest Control

  13. Biological Pest Control • Uses living organisms that are predators to control pests. • Many in-sects are beneficial in controlling other insects. • Pests have natural enemies in the environment.

  14. Mechanical Pest Control • Includes using tools or equipment for control. • The most common example of mechanical pest control used in a greenhouse is the removal of un-wanted plants by hand.

  15. Chemical Pest Control • Includes using pesticides, such as herbicides, insecticides, nematicides, and fungicides. • A pesticide is a chemical used to control pests.

  16. Genetic Pest Control • Utilizes biotechnology by gene transfer or genetic manipulation to make plants resistant to specific pests. • Resistance means that the plants have some trait that repels the pest. • Biotechnology is the management of biological systems for the benefit of humanity.

  17. IPM Practices Used in the Greenhouse. • Pest Entry Prevention • Weed Control • Sanitation Practices • Crop Inspection • Environmental Manipulation • Pest Eradication

  18. REVIEW

  19. List the Major Categories of Plant Pests. • Insects • Nematodes • Weeds • Plant diseases • Animals

  20. DEFINE PLANT PEST: • A pest is any thing that reduces the production or quality of the crop. • Causes injury or loss!

  21. What Are the Pest Control Methods? • Cultural pest control • Biological pest control • Mechanical pest control • Chemical pest control • Genetic pest control

  22. List IPM Practices Used in the Greenhouse? • Pest Entry Prevention • Weed Control • Sanitation Practices • Crop Inspection • Environmental Manipulation • Pest Eradication
