A process for treating foliage by retaining an active agent in contact with the foliage is provided that includes the application of a biologically active ingredient carrier granule. The granule includes a mineral component, a cellulosic component, and a binder flowing upon wetting intermixed with the mineral component and the cellulosic components. A biologically active ingredient is added to the granule to treat the foliage. The foliage in either a dry or pre-wetted state. The contact of the granule with water causes the granule to flow to form a coherent film bound by the binder on the foliage with the active agent retained in the film in contact with the foliage.
