CONTROL WEEDS IN NATURALIZED AREAS AND ROUGHS

Naturalized areas and roughs are becoming a more common focus on golf courses that are considering environmental changes in their property. These are considered low-maintenance, but the level of inputs will impact their quality and appearance of naturalized areas.

Weed control is a key component in maintenance of these areas. In addition to herbicide applications, one of the best weed control practices is mowing once or twice a year. The species composition can make herbicide selection challenging, so a pre-emergence herbicide such as Barricade®, which demonstrates turf safety on most established grasses, will help control annual grass and some dicot weeds.

The extended soil residual of Barricade means applications can be made in the fall after soil temperatures drop below 50° F or in the early spring for summer annual weed control. For late germinating weeds such as foxtails, a second application is recommended eight to 12 weeks later. If a fall application was made, wait until soil temperatures reach 65° F for the second application.
