What is the goal of using mulch in pest management?

Using mulch in pest management primarily aims to suppress weeds and conserve soil moisture, which ultimately supports healthier plants. When mulch is applied, it acts as a protective layer on the soil surface. This layer prevents sunlight from reaching weed seeds, significantly reducing their germination and growth. By limiting the competition from weeds, the desired plants can thrive more effectively.

Additionally, mulch helps retain soil moisture by reducing evaporation. This moisture retention is crucial for plant health, especially during dry periods. Healthy plants are generally more resilient to pests and diseases, making mulch an integral part of an integrated pest management strategy.

The other options do not accurately represent the primary goals of using mulch in pest management. For instance, while providing nutrients may be a beneficial side effect of organic mulch over time, it is not the main purpose. Similarly, the creation of a barrier for pesticide absorption is not relevant to mulch, as its role is more focused on physical benefits in terms of moisture and weed control. Lastly, promoting weed growth contradicts the very essence of why mulch is used in pest management.
