The herbicide $^{14}C$-butachlot[N-(butoxymethyl)-2-chloro-2', 6'-diethylacetanilide] labelled uniformly in benzene ring was incorporated in alginate-based granules to get controlled release properties. The influence of kaoline addition on the formulation characteristics and release profiles were evaluated under a closed dark and an opened sunlight condition. Incorporation efficiency of $^{14}C$-butachlor in alginate-kaoline matrices was over 91.8%. Formulation yield was decreased with increase of kaoline concentration. The release rate from all the granules prepared with alginate was slower than that from the commercial granule impregnated in zeolite. The release rate from the granule containing kaoline was decreased as the kaoline content was increased under both conditions. Losses of butachlor from the leacheate solution of the alginate-kaoline matrices under an opened sunlight condition was diminished by increasing the kaoline content.
