About Blackberry (Rubus oklahomus)
Blackberry is a native shrub that is found across the Noble Foundation's service area. Benefits of blackberry include forage and cover for wildlife. Unfortunately, sometimes this wildlife-friendly shrub is viewed as a problem in fencerows and pastures.

Controlling Blackberry
Chemical
For broadcast applications, use 1 quart per acre Remedy plus surfactant in a minimum volume of 10 gallons per acre. For high-volume foliar applications (spot treatments), use 1 to 4 quarts per 100 gallons plus surfactant and apply sufficient spray volume to thoroughly wet all leaves and stems. Treat while plants are actively growing and after first bloom, usually in late June or July. Control of blackberry after burning or mowing is often unsatisfactory for at least the first year.

Prescribed burning
Burning will decrease thicket stand size and density during the year of the burn. However, in years with adequate moisture, burning may stimulate plant growth.
