Talking through yellow leaves in corn on today's Ag PhD Radio show. Tune in now on SiriusXM 147 or catch our podcast later today.

CRAZY TOP is a corn disease caused by an Oomycete pathogen. Symptoms include tillering & twisting of upper leaves. The tassel resembles a mass of leafy structures giving it a bushy appearance. Crazy top is more common in fields that are flooded early in the season Crop Protection Network

This is a big deal for US farms and ranches: Because of that Big Beautiful Bill everyone's talking about—LLCs, S-Corps, and limited p'ships now get the same treatment as general p'ships under FSA eligibility rules. → No more being forced into a GP structure and giving up

NEMATODE MONDAY: Something special (NOT good) about digging up a root system infected w/tRoot-knot nematode. Symptoms of most plant-parasitic nematodes are just not as dramatic. The galling disrupts the plants normal function leading to stunted unthrifty plants #Nematology #SON

So much bacterial leaf streak in central Iowa. Big differences observed in hybrid susceptibility. Do NOT misdiagnose this for gray leaf spot.

#Corn kernels near the tip often fail. Ears prioritize their lower portion and set kernels by 20 days after tassel. Thus, kernels often abort when energy is limiting. Reasons may include: 🌽Saturated soil ✔️Cloudy days 🌽Nutrient deficiencies ✔️Genetics 🌽Variable growth

Southern rust, tar spot & gray leaf spot = fungi. Bacterial leaf streak & Goss's wilt = bacteria. Properly ID & assess risk for best disease management outcomes. Ask local Extension for more info. Darcy Telenko Alison Robertson Tom Allen Maíra Duffeck 🌾🍄🦠🔎🔬💻📊👩‍🔬👩🏼‍💻 Maddi Shires Mandy Bish

They're here. Reports of white mold mushrooms are coming in from around the state. Chances to manage are running out.

If you are headed to the Ag PhD Field day this Thursday July 31st, come find us at our tent. We will be holding brief but focused discussions on the hour, 8 to 2, on various topics that will more than pay for your trip. We also give away money, yes money, who needs another pen.

It's not unusual to see bacterial blight in soybeans, but it is unusual for it to cause yield loss. Don't worry!

We had a great day Ag PhD Field Day! Thank you, & thank you to everyone who came to see us!

Diplodia ear rot has been found in multiple states in 2025. No mycotoxins are associated with this ear rot in the US and Canada. Ear leaves generally die prematurely on infected ears. Scout prior to maturity to ID. Problematic areas should be harvested as soon as possible to

Cloudy conditions are a major risk factor for white mold. A decrease in solar radiation during the disease's key infection window is predicted to cause increased crop yield loss across the state and region. #Agriculture Crop Protection Network #soybeans Eric Snodgrass Nebraska State Climate Office

Mid-April planted corn not sprayed and sprayed at R1 (mid-July); Now at R5.25. Mid-May planted corn not sprayed and sprayed at R1 (end July); Now at R4. Fungicide doing great job of holding off disease in upper canopy.

Some r starting to see some black on r around those rust pustules. Much of the black spores/spots are still southern rust where it switches to black teliospores late season n attempt to survive. It's NOT all tar spot. Thanks 4 the pic Lily Ziehmer (Woitaszewski)! FMI cropprotectionnetwork.org/publications/a…

Nebraska too. It's not eyespot - it's too hot for eyespot. It's Curvularia. Need help on a disease ID? Send samples to UNLPlant&Pest Clinic

There's a South Dakota program trying to help beginning farmers. Most kids who want to farm but don't have a family farm to inherit never get the chance. Land’s too expensive. Banks won’t touch them. The dream dies before it starts. SD’s Beginning Farmer Bond Program hopes to

Should American farmers, with help from USDA, build up the bio fuel industry and consume all the soybeans we used to send to China? It would only take 10% of the current diesel market to achieve and a price tag similar to what the government has handed out the last two years.
