It's Labor Day weekend, that means it's time for me to see what's happening at the first three Palmer amaranth infestations in western Iowa. The infestations (Harrison, Fremont, and Page Counties) were first reported in 2013. Harrison County had two fields (approximately 50 acres) with...

Our analysis shows that soybean more has been more adversely affected by the 2018 weather compared to corn. Soybean yield potential has dropped while corn yield potential is still high. We are in the midst of critical corn grain filling now and soybean grain filling will be starting soon....
