The month of June has come roaring in with severe weather affecting crops in many different areas. Check out some of these management considerations and resources associated with different types of early-season crop injury.


Some areas received enough wind to cause leaning in corn stands. This time of year, the corn should stand back up within a few days of the storm event. There is a small chance some corn could’ve suffered from greensnap (breaking of the cornstalk) if it is V5 growth stage or larger, but we aren’t aware of any specific cases of greensnap this year.

With the recent flash flooding and subsequent ponding in parts of central, west central, and southern Iowa, many farmers are wondering how long their crops will survive under water and what to do next if the crops don’t survive. With the high temperatures we’ve received since the rain, most emerged crops will only survive a few days in those saturated conditions. As flood waters recede, farmers will need to evaluate how much of the crop survived and the need for replant or filling in thin stands.

We’ve got some helpful resources that I’ve linked below for those farmers needing information on crop survival, replant/filling in crops, and other flood disaster resources.

Some parts of southern Iowa received significant hail earlier this week, resulting in crop damage to corn and soybean. Most corn in the affected area is between the V2 and V6 growth stage, while soybeans are primarily in the VE to V2 growth stage. While prioritizing an immediate call to your crop insurance agent is important, farmers will want to wait at least 5-7 days to evaluate regrowth on hail-damaged crops.

In corn fields that are V5 or smaller, regrowth over the next week should be visible and there should be negligible yield loss. If corn is V6 or larger, careful assessment of damage will be necessary to determine if the growing point is still viable and plants will recover.
