Soluble powders are similar to wettable powders with the on major different; all of the ingredients in the formulation are totally water soluble at the use rate.
They are applied as solutions in water. They consist of one or more active ingredients which are blended and mixed with water soluble inert diluents and surfactants. The active ingredient can be either a liquid or solid. Wetting agents are used to facilitate rapid dissolution in water and spreading on plant foliage. A dispersing agent is not normally required because of the total water solubility of the product. A free-flow aid can be included to inhibit clumping and facilitate easy handling of the product. These formulations are often packaged in water soluble bags to minimize user exposure to the pesticide.
