A Nufarm exclusive, Thistrol® is specifically designed to control post-emerge Canada thistle in green pea crops. Troublesome Canada thistle may result in lower crop yield through weed competition and poor crop quality as thistle flower buds are difficult to remove post harvest. Thistrol also combats common annual broadleaf weeds such as morningglory, pigweed, and lambsquarters and is compatible with many other herbicides for expanded weed control. Count on Thistrol for effective weed control that can contribute to bigger year-end profits.
