Various stand establishment problems, including excessive soil moisture, seedling blights, hail, and frost, force farmers in Ohio to replant corn acreage in late May & early June. Replanting herbicide resistant corn hybrids is more complicated than replanting conventional hybrids. Volunteer corn with resistance to glyphosate and/or glufosinate herbicides may adversely affect the performance of replant corn. A study was conducted at S. Charleston Ohio in 2009-2010 to identify effective herbicide treatments for controlling herbicide resistant volunteer corn. A glyphosate resistant corn was planted in late April and replanted in late May with a glyphosate/glufosinate resistant corn hybrid. Eleven herbicide treatments were considered. In three treatments, glyphosate/non-glyphosate blends (50/50 or 25/75) were planted first and replanted with a glyphosate/glufosinate resistant corn hybrid. The results indicated that when pre-existing plants were allowed to grow, they adversely affected grain yields, and that several herbicide treatments were effective in controlling herbicide resistant volunteer corn.
