Abstract
Herbicide-fertilizer combination granular products are described comprising singular, or blended, basic fertilizer granular materials and impregnated with or coated thereon a herbicidal material for controlling broadleaf weeds postemergence. The weed and feed fertilizer products uniquely are characterized by the size, weight and physical property of the fertilizers and any filler particles contained in the weed and feed fertilizer blend product in that the particle size is substantially in the micro-sized range of 500 to 1500 microns; the particle weight generally is less than one-tenth that of customary regular-sized weed and feed particles; and there is a greater cohesion of the particle to the weed foliage. These micro-sized particles exhibit a significantly higher incidence of contact with and greater adhesion to the foliage of weeds thus providing superior weed control.
