How postemergence herbicides impact cool-season grasses

Researchers tested the influence of three selective postemergence grass, broadleaf and sedge herbicides on growth of Kentucky bluegrass and tall fescue.

Weed control in minimal- and no-mow golf course roughs

To help superintendents eradicate weeds without injuring desirable plants, researchers evaluated 11 rough grasses for their tolerance to three postemergence herbicides.

Weed control in turfgrass: Alternatives to conventional herbicides

Turf managers may not always be able to rely on synthetic herbicides for combating weeds. Scientists outline several non-chemical strategies, including cultural practices and organic products.
