Regional Crop Update 6/10

Jun 10, 2024

Cedar/Scott County, IA
Over the last two weeks, our run of moisture has continued in Eastern Iowa. Corn postemergence applications are nearing the end as we approach the start of postemergence soybean applications. Corn topdress urea applications are in full force as the early planted corn approaches V8-V9. There have been quite a few fields of corn showing sulfur deficiency, but overall, our corn crop should be classified as good/excellent. There have been pockets here and there of hail damage where growers did need to replant. Looking at the extended forecast, we should expect some excellent growing conditions for our corn and soybeans in the coming weeks. 

Jackson/Clinton County, Iowa
Corn and bean planting has wrapped up, except for the isolated areas needing replanting due to hail damage. Ground conditions have become saturated in some places, and farmers have even experienced ponding for the first time in what feels like years. Post-corn applications are moving right along, and in a few days, we could start seeing the light at the end of the tunnel. Overall, the corn crop looks good, and due to the rains, some questionable planting timing decisions have been rectified. The beans are off to a good start, and we could see the first big wave of post-emerge applications starting in the coming weeks. While the rain has done mostly good for the corn and bean crops, it has seemed to be quite problematic for the farmers trying to make first-crop hay. The front half of this week looks good weather-wise, which will be conducive for us to near the end of postemergence corn applications.

Sperry, IA
SE Iowa has been moving right along in the growing season this last month, with most days being over 85 and lots of sunshine. Overall, there is a big spread in crop sizes, with some corn at v6 and some corn just emerging. Some of the bigger weather events this month were the band of hail that went through the north side of Wapello and 2 inches of pounding rain that forced a lot of rotary hoeing two weeks ago. Looking forward, we are looking at a lot of disease pressure from the warm and wet spring, with some reports of tar spots already in corn. Cutworms have also been a significant factor, as corn and soybeans were planted into rye or heavy weed residue in no-till fields. Compaction is also a big deal this year, traffic lines are very visible and, in some cases, two or three stages behind. We didn’t get any ground freeze this winter, and it is very visible anywhere that it didn’t get deep ripped. 

Kasbeer & Annawan, IL
The last two weeks have provided lots of opportunities to apply side-dress nitrogen and post-emergent herbicide onto many of the acres throughout our region. Much of the corn in the area has reached full canopy or will be within the week, while 15-inch soybeans are not very far behind as far as canopy closure. As we reach canopy closure in both crops, we create an even better environment for many diseases and insect pests to thrive out in the field. Therefore, it is critical to check fields for any issues that can potentially be addressed with a fungicide, insecticide, or foliar nutrient pass in the near future.

​Galva/Camp Grove, IL
Northern Illinois is experiencing a bit of a dry spell, with most areas accumulating less than 1” of rain. A long planting window has led to a wide variance of development in both corn and soybeans; however, most corn is V5 – V6, and soybeans are about V3. Cooler, wet weather in May has created the perfect conditions for the onset of crown rot in earlier planted corn. Growers should consider making a post-application of fungicide if they haven’t already. Overall, crop conditions are great in this area, with the exception of some later planted soybeans that are struggling to emerge through crusted ground. The slight rain this area received last week helped with this issue tremendously.

In the dynamic world of agriculture, maximizing crop yields while maintaining soil health and minimizing environmental impact is a constant challenge. Take Off LS, a plant growth regulator, has emerged as a powerful ally for corn and soybean farmers. This innovative product promotes healthier, more robust plants that ultimately lead to increased productivity.

Cedar/Scott County
With 99% of planting completed post herbicide applications have started. While the wet weather has held sprayers off for the time being, it looks like we will get a window in the next week to make most of those applications. Corn has been growing rapidly as we are roughly 100 GDUs ahead of average since April 15th. Pre herbicides should be active with the rain we’ve received but don’t let the lack of weeds prevent you from making that post herbicide application. Continue scouting for early season disease pressure as we continue to have ideal conditions for disease growth.

Eastern Iowa has been able to get the majority of the crop in the ground in between rain showers. Planting progress is sitting roughly 90% on corn and 60%-70% on soybeans. Early planted corn emerged in 7-10 days thanks to warm temps and ample moisture. One thing to watch this spring is insects and disease pressure being higher than usual due to the mild winter. We have seen that firsthand in our alfalfa crop locally with the alfalfa weevil causing early season damage before the first cutting. Make sure to scout your hay crop if you haven’t and contact your local rep if a insecticide application is needed.
