Corn and Grain Sorghum Research Verification Program Weekly Update – July 8, 2011
Author: Kevin Lawson, Program Associate - Corn & Grain Sorghum Verification

The corn fields continue to receive irrigations.  The field in Chicot County is close to irrigation termination.  The field in Drew County should be close next week. The field in Lawrence/Randolph County should go into reproductive stage this week.  No disease has been found in any of the fields.

The grain sorghum fields are ready to scout for head worms.  Both fields were scouted twice this week, and they averaged around 0.25 worms per head the first scout.  The Woodruff County field increased to 1 worm per head the next scout and will be scouted close July 11 because it is still in a stage where worms can cause damage.  The non-irrigated field in St. Francis County caught that last crucial rain we needed to finish the field.  We should be good until harvest in that field.

We will scout again on July 11. Field received around 1.50 inches of rain on July 7, which should finish out the field.
