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.
The industry investigates the agronomic issue finding it can be attributed to many factors including environment, genetics and rapid growth stages.
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.
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.
This year’s program features all new agronomic content to help farmers grow and harvest high-yielding crops. Two of the key sessions: selecting a corn planter that’s right for your farm, and developing a systems approach to success with early-season soybeans. We look forward to seeing you there!
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.
New Rabobank research shows the potential effect of losing this critical shipping channel to the global fertilizer market.
Unlike most leaf diseases, tar spot starts impacting the crop at the bottom of plants. That means fungicides you apply must penetrate and get deep into the crop canopy to provide effective treatment. If you opt to not treat the disease, consider making plans to harvest early and pre-booking some dryer gas.
Scott Beck says the family-owned business markets seed corn in 23 states now, with Nebraska ranking fifth in the total volume of seed units sold. Once finalized, this latest acquisition will be the company’s furthest west production facility.
Wheat streak mosaic virus decimated some fields this season, say K-State Extension specialists. The problem is also showing up and expanding in other key wheat-producing states. What farmers do this fall will determine whether the disease is reined in or takes off again next season.
With product and application costs totaling between $30 and $40 per acre, farmers will be taking a harder look at where they make the investment this season.
New studies highlight how thiosulfates not only supply sulfur but also significantly reduce nitrogen loss by slowing the conversion of ammonium to nitrate in the soil.
The Seilers use cover crops and no-till to improve soil health, reduce input costs and improve profitability.
David Hula believes a high-quality carrier is so critical to the performance of his crop protection products that he loads and hauls all the water to the local airport that his aerial applicator uses.
In some cases, the sulfur deficiency can be traced back to last fall when ammonium sulfate and DAP were taken out of fertilizer programs to reduce costs. In other scenarios, the corn just isn’t getting adequate sulfur — but the problem can be corrected.
Now’s the time to be scouting for the disease, especially where the inoculum is present. Tracking weather data, particularly daily humidity levels, can help you keep an eye on tar spot this season.
The administration is furthering its drone advocacy efforts with a new order expanding Beyond Visual Line of Sight mission approvals and establishing a domestic pilot program for electric Vertical Take-Off and Landing drones.
Alex Harrell, soybean world record holder, says the technology helps him make more accurate and timely foliar product applications, while costing less than using a ground rig or an airplane.
A 25-page criminal complaint alleges the researcher and her boyfriend were attempting to bring Fusarium graminearum into the country. The fungus causes significant diseases in a number of food crops, including corn, wheat, barley, soybeans and rice. Toxins from the fungus are harmful to humans and livestock.
The problem occurs at a specific growth stage – typically between V3 and V5 – as the corn seed roots are handing off their jobs to the first two sets of true crown roots.
Despite being outside the optimum window for tar spot control, this Wisconsin field trial yielded strong results.
