7/28/04.  BLB=1.7/sweep.  Aphids=.05/plant.  BLB population has peaked.  Aphid population still increasing.  BLB 2nd generation may be treated in mid to late August.

8/6/04.  Soybeans R4.  BLB=2.75/sweep.  Soybean aphids=17.6/plant.  BLB populations did rise over last week.  Aphids are close to 20/plant average.  Aphids are mostly on the middle and upper part of the canopy scattered around on leaflets.  No concentrated colonies.
