Abstract

Winter annual weeds have really begun to grow with a vengeance and the recent wet conditions have kept most of the field work to a minimum. Given that most of the corn is already planted, I am hopeful (albeit not confident) that these weeds have been effectively eliminated from the fields. If not, do not delay as they become considerably more difficult to control once they get some growth momentum. In particular, marestail (aka.Horseweed) is extremely tough to manage once it grows beyond the rosette stage. Other winter annuals are also more difficult to manage as they mature.
