Roundup Ready Corn Available in 1998

Some corn hybrids with resistance to glyphosate will be available in 1998, however, quantities will be limited. For the 1998 growing season, only one postemergence application of glyphosate is allowed by label. This application must be made before corn reaches 24 inches in height or the V-6 stage, and the maximum rate for 1998 is 1 quart per acre.
