There are few preemergent herbicides that are effective. Products containing oryzalin, benefin, or trifluralin will provide partial control of germinating seeds. These must be applied prior to germination (late winter to midspring).

Some products you can use include: Bayer Advanced Southern Weed killer: 2 oz. /gal. water per 1000 sq ft. Trimec: 2 oz. /gal. water per 1000 sq. ft. Spectracide Weedstop 2: 2oz./gal. water per 1000 sq. ft. Two applications are usually necessary; make the second application about 10 days after the first. The ideal time to apply is from December to February, preferably on days with temperatures of 60 degrees F or higher. The earlier in the season you apply, the easier this weed is to control. Always be cautious with these herbicides, even at these low rates. Do not apply around the dripline of trees, and do not use in flowerbeds. As temperatures rise and other plants are coming out of dormancy, be aware of and prevent drift of spray to off-target plants, and be especially cautious around vegetable gardens and fruit trees.
