After scouting the Chambersburg plot again today for soybean aphids it appears that the population continues to decrease. As I stated before we never came close to the threshold, however now that hot weather has hit we are starting to see the populations react with a decrease in populations. The beans I'm scouting are in R6 so even if we hit a threshold population now (250 aphids per plant) it would not be economical to spray. If you do have late planted or double cropped beans make sure you still pay attention to the aphids. Hopefully the populations are dwidling all around, however you still may have heavy presure in some areas of the county.
