Iowa could be the nation’s top state this year for corn and soybeans, but both crops are in a race to beat disease pressure that’s gaining momentum. Illinois corn continues to ride the struggle bus, while the soybean crop there is positioned to deliver high yields.

There is still up to 55% of the kernel dry weight left to be accumulated by many corn hybrids at this point — starch that can contribute significantly to grain fill and higher test weights.

With at least four weeks left in the growing season, Ferrie encourages farmers to stay ahead of heavy disease pressure in fields, particularly in what he calls D hybrids — those that punch their yield card late-season.

Corn yield estimates in seven counties surrounding the community of Bloomington indicate farmers there will harvest an average crop, at best. That’s counter to what USDA predicts for Illinois yield results statewide.

The extent of the disease in the state is the worst one ISU Extension pathologist says she has ever seen. Farmers in 17 other states have also confirmed the disease.

Short-stature corn is often planted at higher populations because its architecture allows for better light interception and more efficient use of resources when plants are grown closer together. But that’s not always the case, according to Ken Ferrie, Farm Journal Field Agronomist.

Camaraderie is cathartic. It lifts spirits, gives encouragement and reminds all of us we are valuable. Check out what farmers have to say about this year’s corn crop – the good, the bad and the in-between – and may their experiences lighten your load in the process.

A crop-protection startup is using AI and machine learning to identify and develop new active ingredients it says will help farmers solve issues like weed resistance faster and more economically.

USDA reports 73% of the corn crop nationally is in good to excellent condition – a 5% increase over this same time in 2024. Industry analysts believe the Aug. 12 Crop Production report will boost its estimate for the 2025 crop because of the overall favorable growing season.

Just as corn growers were ready to put their pollination problems behind them, another one comes along. This time, the issue had to do with moisture occurring at the wrong time, and the results are significantly impacting yield.
