Abstract
In general, the 1999 growing season was excellent with regard to weed management. Weather patterns provided frequent rain thus enhancing soil-applied herbicide performance. While these rains also made timely postemergence applications a challenge, the efficacy of herbicides was quite good and larger weeds were consistently controlled. On the down side, these same weather conditions also reduced crop tolerance to herbicides, favored multiple and delayed weed emergence, and caused difficulties for mechanical weed management strategies. Regardless, 1999 was a successful cropping season.
