Herbicides for Control of Field Sandbur

Types

• The Texas A&M University Extension lists the use of oryzalin, benefin and pendimethalin for the control of field sandbur. All chemicals are sold under different trade names.

Description

• Products containing oryzalin are selective preemergence herbicides that retard the germination of weed seeds. Oryzalin controls broadleaf weeds and annual grasses in lawns, vineyards and ornamental plantings. Benefin is a preemergence herbicide that effectively controls broadleaf weeds and annual grasses including field sandbur. Pendimethalin herbicides are both a preemergence and early post emergence control of a variety of annual grasses and broadleaf weeds.

Use

• To control field sandbur, apply two to four weeks prior to expected germination of weed seeds. Avoid applying more than a month before germination, as this reduces efficacy. Remove all grass clippings or leaf debris prior to herbicide application. Water treated areas immediately, as this helps to move the chemicals into the soil.
