Principles of-pest-control

  1. 1. Principles of Pest Control EMW3 1
  2. 2. Definition of a Pest EMW3 2
  3. 3. Definition of a Pest • A pest is anything that: – competes with humans, domestic animals, or desirable plants for food or water. EMW3 3
  4. 4. Definition of a Pest • A pest is anything that: – injures humans, animals, desirable plants, structures, or possessions. EMW3 4
  5. 5. Definition of a Pest • A pest is anything that: – spreads disease to humans, domestic animals, wildlife, or desirable plants. EMW3 5
  6. 6. Definition of a Pest • A pest is anything that: – annoys humans or domestic animals. EMW3 6
  7. 7. Types of Pests • Insects (insecticides) – beetles, caterpillars, aphids EMW3 7
  8. 8. Types of Pests • Insect-like organisms – spiders, ticks, mites EMW3 8
  9. 9. Types of Pests • Microbial organisms (fungicides) – bacteria, fungi, nematodes, viruses, mycoplasmas EMW3 9
  10. 10. Types of Pests • Weeds (herbicides) – plant growing where it is not wanted EMW3 10
  11. 11. Types of Pests • Mollusks – snails, slugs EMW3 11
  12. 12. Types of Pests • Vertebrates (rodenticides, predicides) – rats, mice, birds, coyotes EMW3 12
  13. 13. Pest Control is……. • To control a pest only when it is causing or is expected to cause more harm than is reasonable to accept. EMW3 13
  14. 14. Pest Control is……. • To use a control strategy that will reduce the pest numbers to an acceptable level. EMW3 14
  15. 15. Pest Control is……. • To cause as little harm as possible to everything except the pest. EMW3 15
  16. 16. Pest Control Goals • Prevention • Suppression • Eradication EMW3 16
  17. 17. Threshold Levels…… • Are the levels of pest populations at which pest control action needs to be taken to prevent the pest from causing unacceptable injury or harm. EMW3 17
  18. 18. Avoiding Harmful Effects • Choose the pest control method that will best control the pest with the least harmful effect to the environment. EMW3 18
  19. 19. Integrated Pest Management (IPM) is… • the combining of appropriate pest control tactics into a single plan to reduce pests and their damage to an acceptable level. EMW3 19
  20. 20. Integrated Pest Management (IPM) • To solve pest problems using IPM: – Identify the pest – Is control needed? – What controls are available? – Evaluate the risks and benefits EMW3 20
  21. 21. Integrated Pest Management (IPM) is • To solve pest problems (con't): – choose a control strategy that will be most effective and cause the least harm to people and the environment – use each tactic in the strategy correctly – observe Local, State, and Federal laws. EMW3 21
  22. 22. Integrated Pest Management (IPM) is • Natural Controls – climate – natural enemies – natural barriers – food and water supply – shelter EMW3 22
  23. 23. Integrated Pest Management (IPM) is • Applied controls – host resistance • resistant varieties – biological control • natural enemies – cultural control • plowing, crop rotation, fertilizing, etc. EMW3 23
  24. 24. Integrated Pest Management (IPM) is • Applied controls (con't) – mechanical control • traps, screens, fences – sanitation • remove crop residues, cleanliness – chemical control • use of pesticides EMW3 24
  25. 25. IPM Monitoring (questions to ask) • What kinds of pests are present? • Are the numbers great enough to warrant control? • Have the control efforts successfully reduced the number of pests? EMW3 25
  26. 26. Pest Control Failures • pest is resistant to pesticide Pesticide resistance describes the decreased susceptibility of a pest  population to a pesticide that was previously effective at controlling the  pest.  EMW3 26
  27. 27. Pest Control Failures • incorrect pesticide The wrong pesticide EMW3 27
  28. 28. Pest Control Failures • incorrect application method i.e. The wrong equipment EMW3 28
  29. 29. Pest Control Failures • incorrect pest identification The wrong bug EMW3 29
  30. 30. Pest Control Failures • incorrect dosage i.e. Too much water EMW3 30
  31. 31. Key Points • A PEST is anything that competes, injures, spreads disease, or annoys humans, domestic animals, or desirable plants. • Pest Control is to control a pest only when it is causing or is expected to cause more harm than is reasonable to acceptable. • Integrated Pest Management (IPM) is the combining of appropriate pest control tactics into a single plan to reduce pests and their damage to an acceptable level.
