Yield Loss From European Corn Borer

European corn borer is a serious threat to corn every year and has started to show resistance to Bt traits normally used to contain it. There are two main generations of European corn borer each year. The first generation emerges around the early part of June and can result in yield losses of 5% to 8%. The second, emerging now, can result in yield losses of 2% to 5%. Pioneer research has developed a model to accurately determine when the second generation will emerge, based on when the first moth of the first generation hatched…Hear more


Japanese Beetle Management

Japanese beetles have no known natural predator in the U.S. and are a serious threat to crops. These pests are most established east of the Mississippi River but have a quickly expanding footprint in most other corn and soybean growing states. In most instances, we see these pests extremely localized or not causing enough damage to be concerned. Scouting is the best way to know if more drastic measures need to be taken…Hear more


Corn Pollination and Yield Assessment

Checking the pollination of corn ears gives farmers a quick yield assessment for the season. By taking an ear from the field and removing the entire husk while maintaining the silks, farmers can see whether pollination has occurred. Pollen needs to remain on the silk for around 24 hours before pollination occurs…Hear more

Corteva Agriscience CEO James C. Collins Provides Support of USMCA

Corteva Agriscience CEO James C. Collins testified July 30 in front of the U.S. Senate Finance Committee in support of the United States-Mexico-Canada Trade Agreement (USMCA). Collins spoke about the millions of jobs that depend on trade with Canada and Mexico, the largest agricultural export markets for the United States. 

"The farming community is facing one of the most challenging periods in history due to weather, trade and regulatory burdens, which limit their access to new innovations and safe and reliable seed and crop protection products, at a time when they need to meet the massively growing demand for food supply,” Collins said. “Given this, I was grateful to be asked to testify in front of the Senate Finance Committee in support of the passage of the USMCA, which is critical to protecting farmers by supporting employment and economic growth." …Read more
