  • Chemical controls: using pesticides as a last resort when other methods are not effective

Real-World Examples of IPM in Action

1. Crop rotation and companion planting: rotating crops and planting certain species together can disrupt the life cycle of pests, reducing their populations.

  • Example: In India, farmers use crop rotation and companion planting to manage the cotton bollworm pest. By planting marigolds alongside cotton, they attract beneficial insects that prey on the bollworm.

2. Traps and barriers: using physical barriers or traps to capture or deter pests

  • Example: In California, farmers use sticky traps and row covers to control the western flower thrips pest in strawberry fields.

3. Biological controls: introducing natural predators or parasites to control pest populations

  • Example: In Mexico, farmers release the parasitic wasp _Trichogramma_ to control the corn borer pest. The wasp lays its eggs inside the moth's eggs, preventing them from hatching.

Theoretical Concepts in IPM

1. Economic threshold: determining the minimum number of pests that can be tolerated before taking action

  • Example: In a wheat field, the economic threshold for aphids might be 10 per plant. If the population exceeds this threshold, farmers would take control measures to prevent damage.

2. Pest pressure: understanding the factors that contribute to pest populations and developing strategies to manage them

  • Example: High temperatures, humidity, and wind can increase pest pressure in agricultural fields. By monitoring these conditions, farmers can anticipate and prepare for potential pest outbreaks.

Challenges and Opportunities in IPM

+ 10% is wasted after purchase by consumers (retail and consumer waste)

+ 8% is wasted in food manufacturing and processing

+ 2% is wasted during transportation and storage

Economic and Environmental Impacts

  • Food waste has significant economic, environmental, and social consequences:

+ Estimated global economic losses: $940 billion annually

+ Greenhouse gas emissions from food waste: equivalent to 3.4 million cars on the road for a year

+ Water pollution and contamination from agricultural runoff and processing chemicals

+ Negative impacts on biodiversity and ecosystems
