Which liquid pesticide formulation typically contains a small amount of active ingredient?

A ready-to-use (low-concentrate) solution is designed for immediate application and convenience, typically containing a small amount of active ingredient in a larger volume of solvent or carrier. This form eliminates the need for further dilution or mixing, making it user-friendly, especially for non-professionals or those unfamiliar with pesticide application processes.

In contrast, concentrated solutions usually have a higher concentration of active ingredients and require dilution before use, which is not the case with ready-to-use formulations. Emulsifiable concentrates also present a more concentrated form of active ingredients that must be mixed with water, while wettable powders consist of solid particles that need to be suspended in a liquid, often requiring more handling and preparation. Thus, the unique characteristic of a ready-to-use solution, with its low concentration of active ingredient, sets it apart as the correct answer.
