Today, Matt is back from vacation and talks with Erin about the latest insect activity in Iowa. Soybean aphids can be found in northern Iowa, but at very low numbers. Japanese beetles are feeding in corn and soybean in central counties, and a mixture of caterpillars are feeding in soybean.
It's unusually warm this February episode. Like Bugs Bunny cartoon said - Gosh, it's hot! Matt and Erin talk about accumulating degree days for the state so far in 2017. Northern counties have accumulated between 16-22 degree days, while southern counties have accumulated 50-53 degree days. Erin uses the ISU Agronomy Mesonet to estimate temperatures. Matt also shared that the Toth Lab is noticed honey bee foraging already this year. There may not be much to feed on right now, which is concerning to beekeepers. Matt also shared some information on pyramided host plant resistance options for farmers in Iowa. Finally, Erin encouraged new agronomists to attend the Crop Scout School in Ames on March 25.
