U of A CES 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.

Cyperus esculentus

Use 1.33 oz/A of Outrider with 0.25% nonionic surfactant in 10 to 40 gallons of water per acre as a broadcast application. Apply to actively growing sedges with enough leaf area to intercept the spray. Weeds to be treated should not be mowed or grazed for 2 weeks before or after application. Bermudagrass may be harvested after the two-week period without any effect on Outrider efficacy. Weed response to Outrider is very slow. It may require up to 1 month for weeds to become brown. Tank mixing Outrider with herbicides formulated as amines (including 2,4-D) may decrease the effectiveness of Outrider on sedges. For spot treatment, mix 1.33 oz/A of Outrider in 100 gallons of water with 0.25% nonionic surfactant. Apply this as a spray to wet application.
