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.
Dogfennel, Eupatorium capillifolium
Spray dogfennel when it is 6 to 12 inches tall. At this height, Grazon P+D or Weedmaster at 1 qt/A will give 90 to 100% -control. Research has shown that Remedy Ultra (triclopyr) and PastureGard HL (triclopyr + fluroxypyr) are also highly effective for controlling dogfennel. PastureGard HL at 3 pt/A is the preferred treatment for dogfennel that is more than 3 feet tall.
