While herbicide resistance is not a new issue, the rapid increase in multiple resistant biotypes in waterhemp, giant ragweed, and horseweed (marestail) is limiting herbicidal options. A waterhemp biotype resistant to six herbicide groups (2, 4, 5, 9, 14, and 27) was recently identified in...

While Sporecaster can help farmers evaluate their risk for white mold using infection...
The 2018 Iowa harvest is posing many challenges. Higher than average harvest losses are likely due to excessive soybean shatter, flooded and wet field conditions, and lodged corn and beans.
Harvest losses can only be managed if you know where and why they are occurring. Measuring harvest...

With the 2018 growing season coming to an end, it’s time to bust out the record books and begin logging the most prevalent diseases we’ve seen this year in Iowa soybeans. It’s important to review these diseases so that farmers, agronomists and all of our partners can make informed decisions...
