form regrowth following mowing or brushchopping, which makes 
mechanical control less effective than chemical control. The plants 
should not be allowed to form seeds. Grubbing or pulling out plants 
is practical where few plants are involved or where they occur in 
sparse stands. The plants are easily killed with ester and amine 
forms of 2,4-D and 2,4,5-T, and by commercial brush killers; such 
chemicals should be used on thick stands occurring over large areas. 
The seeds may remain dormant in the soil for years before germinat- 
ing, so that periodic control measures are usually necessary. Live- 
stock will not browse on the plants unless tethered or otherwise denied 
more palatable forage, but the plants constitute a hazard to tethered 
or very hungry animals.
