What a difference a little moisture, cooler temperatures and a few days make!!! Soybean aphid numbers have definitely changes in the last few days. Last week the fields, with the exception of a few hot spots, where essentially devoid of any aphids, are now to fairly consistent low levels throughout the fields. In almost every field I stopped in today I was able to find aphids at about two thirds of the places I looked. The numbers were only a few, but spread out through the fields. The areas that were very heavily infested last week are now completely without any aphids. These observations were quite consistent everywhere from Granite, to Cottonwood, Wood Lake and Echo.
This is not unexpected. This is normally how they increase in numbers. It’s now just a waiting game.
