These images are of root lodged corn at the V12 (twelve visible leaf collars) and VT/R1 (tasseling/silking) stages of development following the occurrence of strong wind events in 2000 (VT/R1 plants) in westcentral Indiana and 2002 (V12 plants) in eastcentral Indiana. One of the major contributing factors that made the plants vulnerable to root lodging in both years was severe root damage by corn rootworm (CRW) larvae in a corn/soybean crop rotation. In 2002, the effects of CRW larval feeding on the nodal roots was compounded by very dry soil conditions during the initial nodal root formation period.

More details about the 2002 wind and root lodging events are available in the accompanying article.
