Which statement about pest formulations is false?

The statement that solutions dissolve readily in water is accurate and reflects the true nature of this formulation type. Solutions consist of a solute completely dissolved in a solvent, typically water in the context of pest formulations. This characteristic is what makes solutions ideal for applications where rapid absorption or effectiveness is necessary.

In contrast, emulsifiable concentrates, granules, and suspensions all have distinct characteristics that are important in pest control strategies. Emulsifiable concentrates are designed for mixing with water to create a stable emulsion, which makes them versatile for various application methods. Granules are solid formulations that can be scattered in soil or applied directly to plants; their slow release can be advantageous for longer-term pest management. Suspensions, although they do need to be shaken before use because the active ingredients can settle over time, still maintain their efficacy while mixed; however, they are indeed prone to separation if not agitated.

Understanding these distinctions is pivotal in selecting the right formulation for specific pest management situations, as each type serves different purposes in agricultural practice.
