<p>This invention provides a dry powder composition which is in the form of encapsulated particles. The particles are comprised of (1) a particulated inorganic salt ingredient such as sodium, potassium or ammonium bicarbonate or mixtures thereof; and (2) a blend of an agrochemical ingredient and a hydrophilic polymer which is adhered as a continuous film coating on the surface of the inorganic salt particles. The agrochemical ingredient can be a mixture of two or more biologically active compounds. The particle film coating functions as a slow-release medium in the presence of moisture.</p> |
