How is puncturevine controlled?

To control puncturevine, eliminate the seedbank. Mowing is ineffective, but hand-pulling is effective. Pull plants each year before they go to seed until the seed bank hidden in the soil is depleted. Hoeing and shallow cultivation can work when performed before flowering. Tilling will not work; it simply buries seed that remains viable for years. Preemergent herbicides can reduce infestations when applied in late winter. Postemergent herbicides (2,4-D or glyphosate) can be used to control existing plants.
