Fall harvest is running on all eight cylinders around here. Almost everyone is cutting soybeans, and the harvest dust proves it! They are coming out pretty dry, too — I’ve heard moistures under 10% are common.

Corn harvest is ramping up as some producers are beginning to get soybeans finished. All the corn I’ve checked has black-layered now and has lost all of its green color.

As I complete this report, the temperature is flirting with the 90-degree mark… in October! It has been dry over the last two weeks. There’s a slight chance of rain starting 10/6, but when it has been as warm and dry as this, I won’t believe it until I see it.

Field crews should continue to take extra precautions to prevent and contain fires. It seems there are a few reported around the state each day. Keep your head on a swivel and look out for one another out there. Be safe!!

More heat and little to no moisture—where have we heard that before? This time, though, the hot and dry weather patterns are helping to propel us through harvest across the Midwest. The entire state of Illinois is experiencing some degree of drought, with the central and southern regions well into a D2 drought. Overall, northern Illinois is sitting around a D1 drought. Across the DeKalb area, corn and soybeans are being harvested as we have hit maturity. Most soybean fields are ready to harvest, with noticeable green stem in some of the fields I have scouted. Soybean pods are filled with good-sized seeds, and harvest should go quickly, with bean moisture dropping too low being a limiting factor. Corn fields are a little behind and, depending on variety and planting date, are at maturity and being harvested. With near-record highs projected into the weekend, corn ears should continue to dry down rapidly and drop from the corn stalks.

Corn prices are averaging $3.80–$4.10 in northern and central Illinois, while soybean prices are between $9.50–$9.80, and prices continue to remain low. I have not seen early averages for corn and soybeans, but the expectation is for a high-yielding harvest, which will hopefully offset the lower commodity prices.

Once again, I wish everyone a safe and happy harvest!

Harvest is progressing well after a brief break due to rain last week. Soybeans are very dusty, with leaves dying prematurely and hanging on the plant. Moisture is below 10% in most fields. Corn continues to dry down as beans are cut.

Rains over the last week have been welcome, but have not provided the much-needed relief from drought conditions. If anything, the rain has slowed the harvest progress for many across Logan County. While on the outside rows, some fields appear ready to harvest, there are still many green plants deep inside the fields. Soybeans have been most affected by the lack of rain, with very few green leaves left on the plants.

Last weekend, we accumulated a little over 3″ of rainfall from several storms. Harvest had just kicked off last week, only to come to a halt while the surface soil dries back out. Unfortunately, this rain came a few weeks too late to help most of our crop. Most of the corn and early beans are already either dead or well into senescence and will not benefit. I pulled a couple of soybean plants that will be ready to harvest in a week or so, and while they had a decent number of pods, quite a few of them were completely flat. There are some double-crop and late-planted beans that are just starting to tinge yellow; they might benefit from the late moisture. Time will tell.

This past week brought some relief from the dry weather in east-central IL, but rainfall totals in the region were generally 1″ and variable, with some areas receiving 0.1″ (IL State Water Survey – WARM Program; Midwest Regional Climate Center – Ag Climate Dashboard). Unfortunately, it comes too late for most of the corn and soybean crop to benefit. That said, during my survey in Ford County this week, I did see a number of pastures, double-crop soybean fields, a few alfalfa fields, and a handful of fields planted to annual forage mixes that will get some benefit from the precipitation as the growing season winds down.

Harvested corn and soybean acres in Ford County were still low—perhaps 10%—with the recent rain stalling progress for a few days. At the time of my survey, more soybean fields had been cleared than corn fields, though there were still a number of corn fields fully harvested or at least “opened up.” All corn fields surveyed were at R6 (“black layer”), but about half were still showing some green in the upper canopy. Tar spot is also easy to find at this point in the season, with heavier pressure in the northern part of the county. However, it appears to have come in late enough not to have greatly affected yields, with relatively full ears on most plants checked during the survey. Of the full-season soybean fields surveyed, most were at R8 (“full maturity”), while the couple of double-crop soybean fields I stopped at seemed to be stuck in R5, struggling to fill pods.

These aerial shots of our fungicide trial show how detrimental disease pressure can be. In this trial, we ran the same mix of max-rate premium fungicide, but delayed half the application by 10 days.

Harvest is officially underway around here. That said, I did have to look around quite a while in today’s travels to find a crew actively cutting soybeans. I did see a few fields that had been taken out in the last several days. Most soybeans are anywhere from 75–100% leaf drop now, with some stem lodging present in almost all of them. Fortunately, they haven’t lodged far enough to be difficult for the combine. I’m cautiously optimistic about soybean yields—many fields probably could have benefited from another inch or two of rain in August, but I was able to find quite a few 4-bean pods now that leaves have dropped.

Much of the corn in the area still has some green in the leaves, but it is fading fast. Some fields have black layered already, and others are almost there. In the fields I’ve visited I have not seen much tip back on ears, which gives me hope that corn yields are going to be average to above average in the area. I’m still a bit worried about stalk quality and standability in some fields, but the ears are looking pretty good.

I’m telling all the farmers I speak with to take extra precautions and have safety briefs with their harvest crews. A dry harvest season obviously brings enhanced risk of fires. Know where your fire extinguishers are, and if you can have a piece of tillage equipment staged onsite and ready to cut fire breaks if needed, DO IT!

We have had a bit of a mini heat wave here in the middle of September, as temperatures returned to near normal compared to the previous two weeks of cooler weather. The warmer temperatures are helping the corn and soybeans progress through maturity, as we are a bit behind the rest of the state, harvest- and maturity-wise. As the rest of the state enters more substantial droughts, areas north of I-80 are still within normal rainfall, with a small pocket near Evanston entering another early drought phase. With little rain in the forecast, I don’t expect many delays with dry down and senescence. Some windy days would help greatly as well.

Disease has emerged in fields due to the cooler temperatures and heavy dews in prior weeks. Tar spot in corn is the main concern, which will build inoculum for future seasons in fields with hot spots, as well as SDS and Cercospora in soybeans. The SDS has done most of the damage it will do, but Cercospora can lead to purple seed stain and dockage at the elevator, so that will be a disease to monitor throughout harvest.

Corn is firing up through the fields, but there is still a lot of green out there. The furthest progressed fields I saw in DeKalb were just reaching black layer, with other fields still at the 60–75% milk line. This warmer, dry climate will help the plants start to dry down in the next couple of weeks. West and south of DeKalb are well ahead maturity-wise, and harvest will be here in a matter of weeks. Corn has strong stands, and I have not seen much, if any, lodging across the region outside of small pockets that had hail damage early in the season.

Soybeans are turning and senescing rapidly. The late start to the season, with cooler temperatures, has prolonged maturity compared to other areas of northern Illinois. Cercospora is the main disease I have seen while scouting, with a small amount of frogeye leaf spot. Beans are still very wet, and very few fields have reached near-complete defoliation. Another week and a half should bring defoliation close to completion.

On a lighter note, apple orchards and pumpkin patches are in full swing, and plenty of fall festivals are on the horizon to enjoy this great weather across northern Illinois.

Harvest is underway in southern Vermilion County. With the hot, dry weather we’ve had, most farmers seem to be focusing on soybeans, likely in hopes of minimizing shatter and header losses. I did see a number of cornfields harvested, but those were mostly seed corn fields and only a couple of production fields. Of the corn still standing, the majority is at R6, or “black layer,” but with some green remaining in the leaves of the upper canopy. I did find a couple of fields still in early R5, or “dent,” yet to reach maturity, but those were few and far between.

As has been the story for much of the region, ear size and tip fill have been relatively variable field to field, with some showing full ears and others an inch or more of bare cob. Soybean fields still standing were generally in the R7, or “beginning maturity,” to R8, or “full maturity,” stages, with a few stragglers still in late R6, or “full seed.”
