Abstract

In 1992 and 1993, rimsulfuron alone at 17, 35, and 70 g ai/ha, and at 35 g/ha plus metribuzin at 280 g ai/ha, respectively, was evaluated PRE and POST for weed control in potato. Rimsulfuron at 35 g/ha PRE and POST controlled common lambsquarters and giant foxtail and when combined with 280 g/ha metribuzin, controlled common ragweed and jimsonweed. Rimsulfuron and rimsulfuron with metribuzin caused slight to moderate chlorosis in new terminal growth of potato but chlorosis disappeared within 3 wk. Potato height, tuber yields, and tuber quality were not affected by rimsulfuron alone or with metribuzin.
