Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
This area has not seen rain in over two weeks and is not forecasted again until 9/6. Disease presence is still low as a result. The dry conditions were exacerbated by high temperatures (upwards of 97 degrees F) last week, which we will see again this weekend. Corn is dented (R5),…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Recent high day and nighttime temperatures have local farmers and crops stressed. In my immediate area in northeast Illinois, the opportunity for “bonus fill” of kernels experienced last year appears very unlikely as the R6 (dent) corn hastens to maturity. Fields with greater water holding capacity are faring much better than lighter soils,…

Again, sounding like a broken record, hit or miss on rainfall for areas in NE Illinois. This past week some fields received inches while others received tenths. While management decisions are dwindling this late in the growing season, we can still learn from field visits. An area in a soybean field that from the road I predicted to be SDS or BSR turned out to be White Mold. …

Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
In soybeans, some feeding by Japanese beetles was found closer to field edges, in addition to both minor and advanced spider mite damage (each in different fields). With the recent rainfall and more moderate temperatures, continued damage isn’t expected but will be monitored. In corn, some western corn rootworm beetles were found but in low numbers and with minimal damage.…

Scouting corn this week, I’m starting to find some leaf disease, mostly lower in the canopy. To date, I have yet to find tar spot in fields I have visited but am aware it has been confirmed in Indiana counties east of NE Illinois. Predicting what if any yield drag may arise from our dry June should be easier to determine as we progress through the reproductive stages.…

It’s hot! Temperatures exceeding 90 degrees for consecutive days in NE Illinois. Despite the ambient temperature, both corn and soy fields are holding up well, but additional rainfall would be welcomed. Most corn fields are at or near R3, the milk stage. Some ears have visible aborted kernels at the ear tip.…

Wheat harvest has mostly wrapped up in NE Illinois. This week, fungicide applications started in earnest, and I observed fields sprayed by plane, helicopter, ground rigs and a drone! Many growers simply include a fungicide application in their management plan;…

Another week with precipitation; July has been much more favorable than June for northeast Illinois crops. Even with the rain, some no-till soy fields are noticeably lagging in growth behind tilled fields in our area, especially on lighter ground. Those scouting fields have an opportunity to evaluate their post herbicide applications.…

Soil Conditions: Moderately Dry (soil is dry, plants may be browning or stressed, water bodies are low)
Some fortunate NE farms received up to an inch of rain this past week. The rainfall helped our soy crop initiate new trifoliates, improving field aesthetics by hiding leaves present when post-herbicides were applied, giving some fields a “dinged” appearance. While recent rainfall was welcomed, signs of a very dry early vegetative season,…

Soil Conditions: Severely Dry (soil is very dry, water bodies are very low, vegetation is stressed)
Another week without a hint of precipitation in most of NE Illinois; soy has basically stopped growing and corn fields are struggling to canopy between rows. My thermometer is registering 99 degrees this afternoon. I truly hope to share a different story next week. There is concern on how long these crops can hang on before suffering significant yield consequences.…
