Study Notes
Integrated Pest Management (IPM) Definition
- IPM is a pest control approach that combines multiple tactics to minimize risks to people, the environment, and the crop yield.
- IPM seeks to reduce pest populations to a tolerable level, rather than eradicating them entirely.
- IPM is a component of Integrated Crop Management (ICM), which involves managing the entire cropping system.
How Plants and Animals Become Pests
- The introduction of non-native pests
- Native organisms shifting their preferred host
- Changes in agricultural practices
- Changes in food quality standards leading to new pest species
Insect Damage Types
- Indirect Damage: Pests feed on non-marketable parts of plants, leading to yield loss.
- Direct Damage: Pests feed on the marketable parts of plants, leading to quality loss.
- Vector Diseases: Insects transmit organisms that cause plant diseases, resulting in yield and quality loss.
- Contamination: Presence of insects or their parts in harvested produce leads to quality loss.
Justification for IPM
- Limitations of Pesticide-Only Approaches: Pesticides have economic, environmental, and health drawbacks.
- Need for Sustainable Solutions: IPM provides a more socially acceptable and economically viable approach to pest management.
Problems with Pesticides
- Economic and Energy Costs: Pesticides are expensive to produce and apply.
- Resistance Development: Frequent pesticide use leads to pest resistance.
- Disruption of Natural Controls: Pesticides kill beneficial insects, weakening the natural pest control.
- Target Pest Resurgence: Pest populations can rebound quickly after pesticide application.
- Secondary Pest Outbreaks: Pesticides can create favorable conditions for new pest outbreaks.
- Human Health Hazards: Pesticides can be harmful to humans, posing acute and chronic health risks.
- Environmental Pollution: Pesticides can contaminate water, soil, and air.
- Wildlife Impacts: Pesticides can harm wildlife populations.
- Pollinator Decline: Pesticides can negatively impact pollinator populations.
IPM Goals
- Increased Farm Profitability: IPM helps avoid unnecessary crop losses, minimizing input costs and maximizing profit potential.
- Improved Environmental Quality: IPM reduces the reliance on pesticides, promoting sustainable agriculture practices.
- Enhanced Public Image of Agriculture: IPM reduces negative perceptions associated with conventional agriculture.
Pest Monitoring, Surveillance, and Scouting
- Pest Monitoring: Systematic tracking of pest presence, population, and movement across a specified area by trained individuals.
- Surveillance: Informal, passive detection of pest presence by farmers at the farm level.
- Scouting: Systematic field inspection, using scientific protocols, to precisely assess pest pressure and crop performance.
Action Thresholds and Economic Injury Level
- Economic Injury Level (EIL): The lowest pest population that causes significant economic damage.
- Economic Threshold (ET): The pest population density that triggers intervention to prevent the EIL from being reached.
- The ET is typically lower than the EIL.
- Action Threshold (AT): Another term for Economic Threshold.
