Before making any plans to plant supplemental forages, be sure to check the plant back restriction interval for herbicides used in the previous crop. Corn herbicides, especially atrazine products, have a long rotation restriction interval for many of the forage options listed below. So check the labels for the herbicides you used this year especially. You can find pesticide labels on-line at CDMS or Greenbook. The Ohio and Indiana Weed Control Guide also lists Restrictions on Crop Rotation on Table 23 on page 187.
