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.

Virginia Buttonweed, Diodia virginiana
Diodia virginiana
This tough perennial is difficult to control with herbicides. Suppression is a more obtainable goal. In limited testing, Chaparral at 2.5 oz/A has been one of the better treatments. GrazonNext HL at 1 qt/A and Cimarron Max at Rate II will provide about six weeks of suppression.
