A pesticide formulation consisting of talc or clay and a wetting agent mixed with the pesticide. When water is mixed with the formulation, a suspension is formed and is used to spray on the target pest.
A finely-divided, relatively insoluble pesticide formulation in which the active ingredient is combined with an inert carrier such as clay or talc and with a wetting or dispersing agent; a wettable powder forms a suspension rather than a true solution in water.
Finely particulate inert material (eg. kaolin) containing pesticide that forms a stable (semi-permanent) suspension when added to water (may require tank agitation to maintain suspension).
