Cultivation is important in controlling many small broadleaves. Dicamba and 2,4-D are low cost options but be careful because they can easily drift or volatilize onto sensitive crops and cause severe injury. Weeds must be in the seedling stage or no larger than the size of a quarter. It could be a good choice used as a buffer near sensitive crops. Bromoxynil alone does not do an adequate job of controlling redroot pigweed.
Corn has a greater tolerance for metribuzin than for bromoxynil.
It can be tank mixed with metribuzin, dicamba, or bromoxynil to broaden the weed control spectrum. Nicosulfuron is best used in conjunction with other methods of control including preplant incorporated herbicides and cultivation of furrows. The Regents of the University of California.
