CURRENT SCOUTING NOTES

6/2/04:  Soybeans VC.  No insects reported.  Some wooly cupgrass starting on east end rows.  Will not spray glysophate yet.  2-3 acres drowned out.

6/9/04:  Soybeans V1.  No insects found.  Don't recommend spraying weeds yet.

6/16/04:  Soybeans V2.  This field has had approximately 13 inches of rain in the last 3-4 weeks.  Soil wet - under a lot of moisture stress.  Too wet to scout properly this week.

6/23/04:  Soybeans V4.  No insects found.  Bacterial leaf blight on some of the lower leaves.  Iron Chlorosis over 10% of the field.  Some drowned out areas to be replanted.  To be sprayed 6-24-04.

6/30/04.  Soybeans V5.  No insects found. V5 - flowering.  Some iron chlorosis.  Taking tissue sample in iron chlorosis affected area.  Beans look good with the exception of the drowned out areas.  I expect it to grow out of the iron chlorosis.
