"We expect that results with glyphosate will be similar to bromoxynil, since both herbicides lack residual activity," Loux said.
It didn't seem to make a difference if Callisto was applied on 20-inch or 37-inch corn, but, Loux added, it's possible that the later application could be more effective in a year when burcucumber emerges in great numbers in late June or July.
"We will hopefully know more about this after another year of research," he said.
Loux first reported findings from the study in the Crop Observation and Recommendation Network (CORN) newsletter, produced by Ohio State's Agronomics Crop Team, a multidisciplinary group of faculty members and educators with OSU Extension and OARDC.
