The rhizomes are usually yellowish-white, somewhat fleshy, and sharp-pointed.
They can penetrate very hard, compact soils, making them more competitive
than most desirable lawn turfgrasses.
Quackgrass stems are erect and stick out above normal lawn grasses.
The leaf blades are twice the width of bluegrass and rough in texture.
A claw-like protrusion (called an auricle) clasps the stem. One of quackgrass's
most distinguishing characteristics is a ring of root hairs every 3/4"
to 1" along the rhizomes. The lower part of the stem is also hairy.
Hand digging to control quackgrass is generally ineffective, since any pieces of the rootstalk left behind will normally generate new plants. Because quackgrass is a perennial and a member of the grass family, selective herbicides will not control quackgrass. The most recommended method of control is the use of a non-selective herbicide, such as Roundup. It is important to note that a non-selective herbicide will kill all grasses or plants that it comes in contact with. For this reason, care must be taken to apply the product only to the quackgrass plants. Four to six weeks later, the dead lawn area can be prepared for new turf or seeding.
