The storms that rolled across the state last week also brought along with them heavy rain, wind, and even some hail. While most areas did receive some rainfall, parts of northwest Iowa missed out and the drier conditions are starting to show. Weeds continue to be the biggest challenge across the state as many are struggling to get their postemergence herbicide applications made with the wet field conditions. Read on for more specifics on what’s happening around the state.

“Corn and soybeans are progressing nicely. Many bean fields were sprayed with herbicide last week or are being sprayed this week. Corn is canopied and looking healthy. Cooler temperatures are helping, but areas are getting dry. A timely rain would be very helpful for chemical residuals and new growth. Insect and disease pest issues are low at this point in the growing season.”

“Corn and soybeans continue to look really good in north-central and northeast Iowa. Corn ranges from V4–V7 for most of the acres, and soybeans range from V3–V5. Farmers are wrapping up nitrogen sidedress operations for corn as well as getting the postemergence herbicide applications completed. Canopy closure has begun on the early planted fields. The corn that is the most mature has really taken off, looking nice and dark green, as the nodal root system has transitioned to the primary root system of the corn plant for uptake of water, nitrogen, and other nutrients. Due to conducive growing conditions, some corn fields are exhibiting rapid growth syndrome.
