The best product would likely be a non-selective weed killer such as Gly Pho-Sel Pro. Gly Pho-Sel Pro with 41% Glyphosate is a high quality fast acting systemic total vegetation weed killer. Sprayed on weeds and grasses, Gly Pho-Sel Pro 41% starts working fast, within 1-2 hours, and kills weeds and grasses on contact, roots and all.
