What are desiccants used for?

Desiccants are substances that are used to absorb moisture and promote drying, making them effective drying agents. They work by drawing water out of materials, which can be particularly useful in various agricultural practices, such as preserving seeds or preventing spoilage of stored grains. By reducing moisture levels, desiccants help inhibit the growth of molds and other microorganisms that thrive in wet conditions, ultimately contributing to the preservation and quality of agricultural products.

The other options, while relevant to different aspects of agriculture and pest management, do not accurately describe the primary function of desiccants. Enhancing crop growth pertains more to fertilizers and soil amendments, attractive agents for beneficial insects relate to insect pheromones or specific plants that draw these insects, and treating soil infections involves fungicides or other treatments rather than drying agents. Thus, the role of desiccants as drying agents is vital for various applications in agriculture, making this the correct choice.
