Flowables or suspension concentrates characteristics: Which description is correct?

• A. Flowables are soluble in water.
• B. Flowables or suspension concentrates form suspensions not soluble in water and require moderate agitation; seldom clog nozzles.
• C. Flowables form milky suspensions and require minimal agitation.
• D. Flowables are solid granules used for soil.

Answer: (B)

Flowables or suspension concentrates are formulated by grinding the active ingredient into very fine particles that are dispersed in a liquid. Because these particles do not dissolve in water, the product forms a suspension rather than a true solution. To apply evenly, you must keep that suspension moving with at least moderate agitation during mixing and spraying; without adequate mixing, the particles settle, leading to uneven application and potential nozzle clogging. When mixed and sprayed properly, flowables typically produce a uniform, milky suspension and function well without frequent nozzle plugging. They are not solid granules used for soil applications, which would describe a different type of formulation.
