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
variously called, Dogfennel, Cypress Weed, and Texas Cedar.
Greenbrier control is difficult regardless of the methods or herbicides used. Apply Weedmaster (2,4-D + dicamba) in May as either a spot or broadcast treatment. Use a 2% solution for spot application and 2 qts/A for broadcast. Add 0.5% nonionic surfactant. Later treatments are less effective because the waxy layer on the leaves matures and thickens as the growing season progresses. Follow-up applications when regrowth appears are essential.
