Grazon PC herbicide is a water soluble liquid product containing picloram. Use Grazon PC in rangeland and permanent grass pastures to selectively control annual, biennial, and perennial herbaceous weeds such as bitterweed, bursage (bur ragweed, woolyleaf povertyweed), broomweed (annual), horsenettle, locoweed, pricklypear, ragweed (common, lanceleaf, western), snakeweed (broom snakeweed), tasajillo, and thistles. For equal or improved control of such weeds along with many species affected by 2,4-0, use Grazon PC in tank mixtures with 2,4-0 low volatile esters or amines or with Remedy* herbicide. Applications made according to label directions usually give excellent control of most annual and perennial herbaceous broadleaf weed species. Certain more resistant herbaceous and woody species may require repeat treatment in subsequent years.
