Which of the following describes a typical use of granular applicators?

Granular applicators are specifically designed to distribute dry particles over a designated area, making them an essential tool in various agricultural and horticultural practices. This method allows for the even distribution of granular fertilizers, herbicides, or pesticides on soil, water surfaces, and foliage, ensuring that the active ingredients are adequately placed where they can be most effective.

The use of granular applicators is particularly beneficial in scenarios where controlled release of the product is required or where targeting specific areas is important. By applying dry formulations, they can help in reducing off-target application and provide a sustained release of the nutrients or pesticides into the environment, enhancing effectiveness while minimizing environmental impact.

Other methods like spraying liquid insecticides focus on applying a different state of matter and are not well suited for granular applications. Similarly, dusting or injecting methods pertain to specific application techniques not involving the distribution of dry granules. Hence, the unique capability of granular applicators to distribute dry particles makes this answer the most accurate in the context of their typical use.
