*3.2.1.5 Water-soluble powders (SP's)*

Water-Soluble Powders (SP's) are water-soluble formulations of solids/powders, in which the a.i.'s (and solid diluents) are easily dissolved in water. The technical grade material is formulated into a finely ground solid, packed and sold, for adding to a spray tank with water, where it dissolves quickly without any binders or surfactants, and spraying without constant agitation. Some examples of common SPs include *acephate* formulations with trade names *Acephate Tur*f and *Acephate PCO Pro 97.4% a.i.*
