CURRENT SCOUTING NOTES

6/3/04.  Soybeans V1.  Corn ?  No insects reported.  Weeds getting ahead of the crop due to wet weather delaying Roundup application.  Spraying on May 26 is working and the rest of the farm was sprayed on June 3 which will take off the current flush.  Plenty of wet areas.

6/8/04.  Soybeans V1.  Corn V4.  Corn population: 32-36,000.  Soybeans:  160,000.  Roundup working very well, all weeds dying.  Fields wet but not ponded.

6/17/04:  Soybeans V3.  Corn V5.  No insects reported.

6/26/04:  Soybeans V6.  Corn V6.  No insects reported.

7/2/04.  Soybeans V6. Corn V7.  Major portions of corn field showing N deficient.

7/8/04.  Soybeans R1.  Corn V8.  Corn height is very uneven, but looks good from the ground.  Aerial photos taken on July 8 shows very uneven corn and yellowing on the majority of corn fields in Howard County.  Lower areas are under water and drowned out.  5.2" of rain on July ?.  I suspect many corn fields will run out of nitrogen before the season is over.

7/12/04.  Soybeans R1.  Corn V7. No insects reported.  Another 1.5" rain.

7/19/04.  Soybeans R2.  Corn V11.  No insects reported.  Nitrogen deficiency is showing up in corn.  Bottom leaves are fired.

7/27/04.  Soybeans R2. Corn R2.  BLB = 4 per 20 sweeps

8/02/04. Soybeans R3.  Corn R3.  No insects reported.

8/12/04.  Soybeans R3.  Corn R3.  No insects reported.

8/18/04.  Soybeans R4.  Corn R4.  BLB= 1 per 20 sweeps.  Corn yield estimate = 183 bu. where N was side dressed, 127 bu. where no additional N was applied.  N deficiency very evident visually and from aerial observation.

8/26/04.  Soybeans R5.  Corn R4.  BLB = 2 per 20 sweeps.  Beans are waist high and look excellent, but need time and no frost.  Corn is the same story as previous weeks.  Areas short of N will have reduced yields.
