Crop specialists at South Dakota State University's tent at Dakotafest were buzzing about reports of lodged corn in the state.
Farmers had been calling in about lodged corn. At Dakotafest, a number of growers from various parts of the state stopped by SDSU exhibits to report damage and get some answers.
"It's mysterious," says Bradley Ruden, interim manager of the SDSU Plant Diagnostic Clinic. "The root balls are small and stunted and it doesn't seem to be due to corn root worms or herbicides."
All of the reports involved Bt corn root worm hybrids.
There are enough cases in enough different areas that "we going to try to find some answers," he says.
