Pasture Weed Control Database

The Pasture Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-522. The weeds are arranged alphabetically by scientific name because common names vary. For example, in Arkansas, Eupatorium capillifolium, is variously called, Dogfennel, Cypress Weed, and Texas Cedar.

Hordeum pusillum
Glyphosate must be applied in January or February while the Little Barley is small to achieve effective control in dormant bermudagrass. A good rule of thumb is waiting for the high to reach 50 degrees three days in a row. Glyphosate works very slowly in cold weather. Use one quart pera acre of 41% active ingredient glyphosate. Pastora applied in the same time period at 1.5 ounces per acre is also effective.
