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.
Oaks, Quercus
It is possible to achieve partial control of some oak species using 2,4-D alone at 2 qt/A. Improved control can be achieved by using a mixture of 1% Grazon P+D plus 0.25% -Remedy Ultra as an individual plant leaf spray. Add 0.25% nonionic surfactant. Basal bark treatments are very effective on oaks with stem diameters of 4 inches or less. Mix 1 quart -Remedy Ultra Ultra with 3 quarts diesel fuel, vegetable oil or light mineral oil and apply to the lower 18 inches of the stems with a Conejet 5500 X-1 or X-3 nozzle. -Agitate the mixture before spraying. JLB Oil Plus is a ready-to-use basal oil carrier that may be used in place of diesel fuel.
