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.

Pricklypear, Opuntia humifusa
Opuntia humifusa
Employing individual plant treatment, spray pricklypear with a 1% Surmount solution plus 0.5% nonionic surfactant. Use of Hi-Lite Blue Dye will help avoid spraying the same plant twice and show the extent of the coverage on treated plants. Apply during active growth. Do not spray under desirable trees. Do not spray wet pads. Be patient, Surmount works very slowly. It may take 1 to 3 years for complete control. Grazon P+D at 2 qts/A has also proven effective.
