12 What is Integrated Pest Management? In 1996 Congress Integrated Pest Management (IPM) is "a sustainable approach to managing pests by combining biological, cultural, physical, and chemical tools in a way that minimizes economic, health and environmental risks.

13 What is Integrated Pest Management?

14 Four Goals of Integrated Pest Management 1.Set Action Thresholds 2.Monitor and Identify Pests 3.Prevention 4.Control tools Biological Mechanical Chemical

15 A Brief History Early agriculture was diverse

16 A Brief History Monoculture vs. diverse polyculture

17 A Brief History Petroleum-based farming

18 A Brief History Concerns with petrochemicals

19 A Brief History More Concerns: Resistance Resistance to chemicals Weed resistance to tillage

20 More Concerns: Fossil Fuels Petrochemicals and sustainability

21 More Concerns: Cost Cost of pest management rising Cost reductions using IPM GA nurseries survey: 83% reduction NZ : study found pest management reduction cost by one-third in nurseries

22 Pest Management Today Selective chemical products: GMOs, biopesticides Tradeoffs Biologically intensive > agrochemically intensive Training and knowledge

23 IPM is a scientific, step-wise approach that "integrates" tactics based on knowledge of your pest

24 Using IPM IPM Practices Conventional Organic farms

25 Using IPM

26 Using Ecology in Pest Management Habitat Diversity Niche Disturbance Life Cycle Plant Succession

27 Habitat - begins in the soil

28 Plant Succession = changing habitat through time

29 Plant Succession Succession = plant community change Plants have differing responses to change based on successional stage Tillage = Disturbance of habitat Sets succession back Conservation tillage

30 The Niche Concept Ecological Niches = Organism roles Predator, prey, competitor, host Niches in weed management

31 Using a Biologically Based Approach Example: Codling moth, Cydia pomonella Resistance to chemical control Pheromones and mating disruption, degree-day models

37 IPM Goals Know your Pests Prevent Pests Reduce Pests efficiently Control population growth using biological, cultural, chemical strategies Keep the pests below the economic injury level

38 IPM Goal 1. Set Action Thresholds

39 Goal 1. Set Action Thresholds Thresholds change based on the crop, size Not all crops have action thresholds Colleen Burrows, WSU Whatcom Cty IPM

40 Goal 2. Monitor and Identify pests Beneficial vs pest insects

41 Goal 2. Monitor and Identify pests Beneficial vs pest insects

42 Goal 2. Monitor and Identify pests Diseases vs. nutritional deficiencies

43 Goal 3. Prevention Disease prevention use resistant variety Pathogen Host Environment

44 Goal 4. Controls IPM Combines Techniques Biological Chemical Mechanical
