1. Integrated Pest Management
IPM systems

2. Pest management
Traditionally growers used the cheapest and most effective method to control pests
Biological method
Chemical method – most commonly
Cultural method

3. What is IPM
IPM = integrated pest management This is where a grower uses a combination of methods to prevent pests and diseases

4. Why use IPM? IPM is relatively modern
Came about because pests and diseases have developed resistance to traditional techniques (chemicals)
Consumer concern
Spray free vegetables and fruit

5. Method This depends on several factors: The crop your growing
The natural pests and diseases about
The cultural control methods available
Environment factors

6. Example:

7. How does IPM work Set action thresholds (limits)
Monitor for pests/diseases
Prevention techniques
Control

8. Pest and disease thresholds
Thresholds are a limit of pests or disease that can be in a crop. Once this limit is met action needs to be taken – spraying Its not cost effective to spray if the numbers of pests are below these limits

9. Monitoring is key
Crop montitoring is what makes IPM effective The grower regularily checks the pest and disease levels It relies on having thresholds

10. Prevention techniques
First line of defence
IPM programs work to manage the crop, lawn or indoors space to stop pests becoming a threat
Prevention techniques:
Rotating crops
Using pest resistant varieties
Planting pest free rootstock

11. Control Techniques
Once action thresholds are met through monitoring and prevention techniques are not working control is needed
Control is based on effectiveness and risk
Less risky controls are used first
