If so, what time of year should I spray? They bloom later in the year. Will it kill my Bermuda grass?
Although a triclopyr herbicide such as Southern Ag Brush Killer may control goatweed, this herbicide is not labeled to control this plant, nor is it labeled for use in home lawns. If you are referring to goatweed (Scoparia dulcis), then you will likely need to spot treat using a non-selective herbicide like RoundUp QuikPro. If you are referring to goathead/puncturevine (Tribulus terrestris), then you can use a pre-emergent called Surflan to prevent this weed in warm-season turf like Bermuda and around many established ornamental plants.
