The rapid progression of corn planting followed by the current wet period prevented many growers from applying preemergence herbicides and nitrogen fertilizer when fields were planted. Both corn and weeds will have emerged in many of these fields by the time field work resumes. Growers in this predicament should adjust their weed management program rather than trying to force their previously planned herbicide treatment into the current situation. Neither Balance Pro nor Axiom allow application following corn emergence. Thus, we feel these combinations should be avoided.
Several options are available that provide effective control of emerged grasses and broadleaves.
These programs will provide more consistent control of emerged weeds and avoid the high risk of crop injury associated with fertilizer-herbicide combinations. Applying the herbicide a few days prior to broadcast applications of UAN will reduce the potential for reductions in herbicide performance caused by foliar burning by the nitrogen.
