Surflan Pro Herbicide is not labeled for tumbleweed. A great option for tumbleweed pre-emergent control would be Casoron 4G Herbicide. You can apply it either in early spring before seeds of annual weeds germinate or afer cultivation has removed the growing weeds. Distribute granules uniformly over the soil surface. If treatment is followed by application of 1/2 to 1 inch of water by overhead irrigation, the lower rates are recommended. Shallow incorporation immediately after application is recommended in southern areas. In other areas, shallow incorporation or sprinkler irrigation is suggested when applications are made during periods of high temperature. This product can be applied in late fall to prevent weeds as well.
