Crop Watch 2025: Corn Yield Threats
Several threats are impacting corn yields this season, including overly tight tassel wrap, Southern Rust and tar spot.
Unscripted: ‘Overly Tight Tassel Wrap’ Affecting Pollination?
Ken Ferrie, Farm Journal field agronomist, joins Tyne Morgan and Clinton Griffiths to shed light on crop conditions, particularly pollination issues.

In addition to keeping a watchful eye for southern rust and tar spot, some farmers and agronomists have been surprised to find pollination issues due to “overly tight tassel wrap.” Let us know how your corn crop is faring,
Got tar spot? Economic data shows two passes can offer ROI, depending on the hybrid. However, if your crop got dinged at pollination that’s a different scenario and might require a revised game plan that takes yield estimates into consideration.
Southern rust has now been confirmed in at least 15 states, and with high heat and humidity this week, along with strong winds, agronomists are encouraging farmers to scout their corn fields, as conditions are ripe for the disease to spread.
More reports of ‘overly tight tassel wrap’ are coming in across the Corn Belt – including from the reigning world champion corn grower. Hula shares how he strategically uses his planter to minimize pollination risks.
An up-and-down early growing season in the Upper Midwest left many soybean farmers with small, stressed soybean plants. Find out what the carbon penalty is and learn strategies to beat it and save the crop.
Both diseases are showing up earlier this summer than last year, according to Daren Mueller, Iowa State University plant pathologist. He says a new interactive tool from the Crop Protection Network can help farmers locate these diseases, and others, faster.
So far, the problem has been confirmed in four states. Agronomists are encouraging farmers to scout crops, estimate yield impacts in affected fields and determine whether to make adjustments to marketing plans.
Many early-planted soybeans in the Midwest are in the R2 to R3 growth stages now, ideal treatment timing for most disease issues. Agronomists offer three reminders to help you make the call — plus a fourth tip on herbicide rescue treatments.
Farmers and aerial applicators tell Randy Dowdy and David Hula some of the key considerations for effective fungicide applications are timing, droplet size and product reach in the crop canopy.
As big yield estimates are being thrown around so early, it’s stoking an intense debate. However, that’s not stopping the trade chatter. With talk of a new national corn yield record, it’s pressuring prices, with many farmers staring at cash corn with a $3 handle.
