What term describes a pesticide that is dry, small, and ready to use, but not uniform in shape?

The correct answer is granule because this term specifically refers to a type of pesticide formulation that is composed of dry particles that are small and ready for application. Granules are typically used for their slow-release characteristics, allowing them to effectively control pests over an extended period. The irregular shape and size of granules may affect how they spread when applied but do not hinder their effectiveness as a pesticide.

In contrast, aerosols consist of liquid formulations dispersed in a gas, suitable for creating a mist or spray; they do not fit the description of being dry or solid. Solutions refer to liquid mixtures where the pesticide is completely dissolved, lacking the solid characteristics associated with granules. Liquids, while also being a form of pesticide application, imply a uniform liquid form rather than solid, dry particles. Thus, understanding the specific characteristics associated with granules clarifies why this is the correct choice in this scenario.
