Which of the following is an example of cultural control?

1. Applying herbicides

2. Releasing sterile male pests into the population

3. Changing sanitation practices

4. Pruning and fertilizing plants

The correct answer is: Pruning and fertilizing plants

Cultural control refers to practices that modify the environment to make it less conducive to pests, diseases, or weeds. Changing sanitation practices is critical, as it limits pest access to food, shelter, and breeding sites. Pruning and fertilizing plants also exemplify cultural control because these practices can improve plant health, enhance growth, and increase resistance to diseases and pests. By appropriately pruning plants, you can remove diseased or infested parts, which reduces the overall pest population. Fertilizing provides nutrients that support stronger plant growth, making them less susceptible to pest damage. Similarly, managing water and avoiding plant overcrowding are also cultural methods that promote healthier plant ecosystems, ultimately leading to a reduction in pest problems. This holistic approach to pest management focuses on creating an optimal environment for plants while discouraging pest infestations.
