QAL Laws & Regulation Practice Exam

Which of the following is an example of a physical pest management method?

1. Crop rotation

2. Fencing and netting

3. Insecticidal spray

4. Soil sterilization

The correct answer is: Fencing and netting

Fencing and netting represent a physical pest management method as they create barriers that physically prevent pests from accessing crops or vulnerable plants. This strategy is a direct, non-chemical way of protecting agricultural products from a range of pests, such as insects, birds, or larger animals. By obstructing the pathway of these pests, fencing and netting effectively minimize damage while allowing for the healthy growth of plants. Other choices reflect different pest management strategies. Crop rotation is a cultural practice that involves alternating the types of crops grown in a specific area to disrupt pest cycles and enhance soil health. Insecticidal spray is a chemical method that relies on pesticides to manage insect populations, which does not align with the physical approach. Soil sterilization, while aimed at controlling pests within the soil, typically involves chemical or physical alterations to the soil environment rather than creating physical barriers. Thus, fencing and netting stand out as the correct choice, as they consist solely of physical interventions without the use of chemicals.
