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.
