The disease is causing turmoil for farmers who have a large crop in the making. In some cases, a Hail Mary fungicide application at R4 up to early dent (R5) might make sense this season, say agronomists.
On the heels of Crop Tour, Pro Farmer projects corn yields at 6.1 bu. below USDA’s August estimate, while soybean yield numbers are nearly aligned.
The Minnesota corn crop is going for gold. Pro Farmer Crop Tour scouts expect the crop will reach a record 202.86 bu. average, if it can outpace southern rust and tar spot. Scouts peg the Iowa corn crop at a 198.43 bu. average, but it also faces disease challenges.
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.
One concern cited is that USDA tends to aim too high with its August yield estimates, based on what the data shows from the past decade. The other concern is how strong demand will be, given corn carryover projections.
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.
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.
