The premium performance selective granular pre-emergent herbicide. Pre-San® Granular Selective Herbicide is recommended for pre-emergent control of crabgrass, goosegrass and Poa annua as well as other listed annual weeds in turfgrass. The Pre-San labels cover virtually all the major turfgrass species. One of the primary criteria for selecting a pre-emergent herbicide is the tolerance of the turfgrass to the herbicide. The tolerance of established bentgrass (even on greens) to bensulide at labeled rates has been cited as good to excellent by users and researchers. Golf course superintendents may use different formulations for the initial and sequential applications. For example, Pre-San Granular 7G and Pre-San Granular 12.5G may be used during cold periods in early spring and Bensumec™ 4LF may be used later in the year. Bensulide applications to bentgrass will provide effective weed control and maintain the uniformity, density and color of bentgrass. Ratings for turfgrass tolerance and weed control are the reasons that these pre-emergent herbicides containing bensulide are the preferred choices for bentgrass greens, tees, aprons and fairways.
