Pasture Weeds

   It is still a good time to scout pastures spring weeds, such as thistles and buttercup, while still in the rosette or vegetative stage. Applying herbicides to small actively growing weeds is critical to achieve maximum control and prevent seed production.
   Products containing 2,4-D, dicamba, triclopyr, picloram, aminopyralid, or pre-mixed products containing two or more of these products provide good to excellent control of broadleaf weeds in pasture. Use caution: these products are safe at labeled rates on grass species but can kill or severely injure desirable broadleaves in grass-legume pasture mixes. In some cases spot treatment of areas may provide adequate control. Always read label for proper rates, target weeds, and grazing or hay harvest restrictions. ∆
