Postemergence Weed Control in Corn
Some of our early planted corn is ready for postemergence weed control. Suggestions for effective control include the following:
When using atrazine with oil, annual grasses are best controlled when less than 1 1/2" tall. Bladex 80W or 90DF can also be used postemergence but omit the oil. Tandem in combination with atrazine or Bladex increases postemergence activity. Bladex should be used when corn is 4" or less. Apply Marksman when corn is under 5".
Buctril or Brominal alone or in combination with atrazine should be applied when most broadleaf weeds are under 6". Laddok should also be used before broadleaf weeds reach 6". Use drop nozzles when applying Banvel or 2,4-D to taller corn. Observe all label cautions on crop heights, rates, and safety to nearby crops, gardens, and windbreaks.
