Corn and Grain Sorghum Research Verification Program Weekly Update – July 1, 2011
Author: Kevin Lawson, Program Associate - Corn & Grain Sorghum Verification

On the morning of June 28, a severe storm hit Lawrence and Randolph Counties, striking another harsh blow to the corn in Northeast Arkansas.    The field there was growing very rapidly and was at V13 stage.  The winds reached 70 miles per hour causing severe green snap in the field.  The field had damage that was similar to what was done in Greene County just a couple of weeks ago.  This same storm also blew over some more of the corn in Greene County.  Plants were snapped right at the ear.  On some of the plants the ear remained, and on some, the ear broke off also.  Chicot County should be at irrigation termination next week, and Drew County will not be far off.

Both grain sorghum fields were scouted for midge.  The field in St. Francis County was sprayed, but the field in Woodruff County didn’t need to be sprayed.  I visited a farm in Desha County this week, and worms were present.  We will scout both fields next week for worms.
