Post Emergence Sand Bur

Asked June 23, 2016, 5:53 PM EDT

Can Roundup WeatherMax or PowerMax be used on Texas coastal grasses in July without harm? I'm infested with sand bur. Should I spray before cutting or after?

You can spray Roundup on coastal to control sandbur immediately after a hay cutting. A light application in a 4 or 5 day window right after hay harvest is there to utilize. I would encourage you to go on the lighter side of instead of heavier side in terms of herbicide used.
