Large seed production per plant. Remove large plants with a digger. Disposal Compost or mulch. For best results put the spray nozzle into the middle of the plant and give it a five second burst. Alternatively graze, cut or burn foliage and spray regrowth.
Control exacerbates fire hazard.
Recommended Approach Grub out small plants. For individual large plants put Roundup into the middle of the plant. For larger areas spray with Gallant.
