QAL Laws & Regulation Practice Exam

Changing irrigation practices is considered a cultural control because it can reduce pest problems—True or False?

1. True

2. False

3. Only in specific conditions

4. Not applicable

The correct answer is: True

Changing irrigation practices is indeed considered a cultural control, as it can significantly influence pest populations and reduce problems associated with them. Cultural controls are methods that alter agricultural practices to create an environment less conducive to pests. Adjusting irrigation can lead to changes in soil moisture levels, which directly affect pest habitat and their life cycles. For instance, overwatering can create conditions that favor certain pests, such as fungi or insects that thrive in wet environments. Conversely, by managing irrigation more effectively—such as using drip irrigation or modifying the timing of watering—farmers can reduce excess moisture, thus minimizing the risk of pests proliferating in the crop areas. This approach is particularly relevant in Integrated Pest Management (IPM) strategies, where a combination of methods is used to control pest populations while minimizing the use of chemical pesticides. By adopting sustainable practices like changing irrigation, farmers can enhance crop health and productivity while managing pests more effectively. Other choices may suggest complexities or limits to the effectiveness of irrigation changes, but in general practice, this method is recognized for its potential to mitigate pest issues.
