Disease pressure is building across Iowa, but it's not the same story everywhere.

In this episode of Acre Advantage, Dan Bjorklund is joined by Jaci Winkelpleck and Kade Schmidt to break down what they're seeing in fields across the state. From bacterial leaf streak and gray leaf spot to southern rust, tar spot, and the emerging Curvularia leaf spot, the team discusses what is developing, where it's showing up, and what growers should be watching over the coming weeks.

The conversation also explores how SkyScout is helping agronomists identify high-risk areas faster, along with new POMA technology that may detect tar spot infections before visible lesions appear. The team shares yield data from fungicide trials, discusses when a second fungicide application may be warranted, and reviews how nutritional products performed under high-stress conditions last season.

• Current disease pressure across Iowa corn and soybeans
• Southern rust, tar spot, bacterial leaf streak, and Curvularia updates
• How SkyScout is prioritizing scouting locations
• Early disease detection with POMA technology
• Fungicide timing and ROI from 2025 field trials
• Nutrient and biostimulant performance under weather stress
• What growers should monitor over the next several weeks

As Iowa crops enter one of the most critical months of the growing season, what should growers be watching?

In this episode of the Acre Advantage Podcast, Landus Technical Agronomist Dan Bjorklund is joined by longtime agronomist Dave Lunke to discuss how spring planting conditions are still influencing fields today—and what July weather could mean for the rest of the season.

They cover the lasting effects of cool soils and uneven emergence, why root development matters more than what's visible above the canopy, and what Landus agronomists are finding through field visits and SkyScout® imagery. The conversation also explores sulfur deficiencies, early disease observations including tar spot, anthracnose, and gray leaf spot, emerging insect pressure, and how weather during the next several weeks could shape yield potential.

Whether you're evaluating fungicide timing, monitoring disease pressure, or simply wondering what to expect as crops approach tasseling, this episode offers practical, field-tested insights to help you make informed decisions throughout July.

In this episode:

• How spring planting conditions continue to impact crop performance
• Why July weather often determines the rest of the growing season
• Early observations of disease pressure across Iowa
• Nutrient deficiencies and what they're telling us
• What to watch as corn approaches tasseling and pollination
• How SkyScout® is helping identify issues before they become widespread

Tar spot has already been confirmed in multiple states, including Iowa, earlier than many agronomists expected. In this episode, Dan Bjorklund sits down with Kade Schmidt of Intelinair, the technology company behind SkyScout, to discuss what they're seeing across the Corn Belt and what it could mean for the rest of the growing season.

The conversation covers early disease detection, how thermal imagery and field analytics are helping identify issues before they're visible from the road, and why current weather conditions have both agronomists and farmers paying close attention. Dan and Kade also discuss fungicide timing, nutrient loss concerns following heavy rainfall, and the value of targeted scouting throughout the season.

Topics include:

• Early tar spot detections across Iowa and the Midwest
• How SkyScout identifies disease pressure and crop stress
• Fungicide timing and ROI considerations
• Nitrogen and sulfur loss after excessive rainfall
• Thermal imagery, NDVI, and scouting strategies
• What growers should be watching for over the next several weeks

In this episode of Acre Advantage, Technical Agronomist Dan Bjorklund is joined by Landus Sales Agronomist Jeff Aronson, a longtime weed management expert serving northern Iowa and southern Minnesota. Together, they discuss strategies for controlling tough weeds like waterhemp and giant ragweed, the importance of strong pre- and post-emergence herbicide programs, and how growers can stay ahead of weed resistance while protecting yield potential throughout the growing season.

In this episode of The Acre Advantage Podcast, Landus Cooperative’s Michael Weidner sits down with grain merchandiser Scott Stoller to break down what’s happening across the grain markets as planting season wraps up across the Corn Belt. From weather and crop progress to volatility driven by global trade news, the conversation dives into the challenges and opportunities growers are facing right now.

Michael and Scott discuss the emotional swings in the marketplace, why old crop grain movement matters more than ever, and how growers can approach new crop marketing decisions in an uncertain environment. They also cover basis trends across the Western and Eastern Corn Belt, shifting farmer behavior, risk management strategies, and the importance of having a disciplined marketing plan in place before the market moves.

Whether you’re focused on corn, soybeans, or wheat, this episode offers practical perspective on managing risk, protecting profitability, and positioning your operation for the months ahead.

In this episode of The Acre Advantage, Dan Bjorklund and Dave Lemke break down how early-season stress—cold soils, uneven emergence, and disease pressure—can quietly impact your crop all season long.

From crown rot risk in corn to slow soybean emergence, this conversation focuses on what’s happening right now in the field—and what growers should be watching next.

• Why early stress compounds throughout the season
• How cold, wet soils increase risk for crown rot and root diseases
• What to check at V5—including how to evaluate the crown
• How uneven emergence impacts yield potential
• Why genetics and field conditions matter more in variable years
• When a V5 fungicide application may be worth considering
• How tools like SkyScout help you scout smarter and respond faster

• Early decisions set the tone for the entire season
• Stress now doesn’t disappear—it compounds
• Scouting is critical between emergence and V5
• Protecting plant health early protects yield later
• Never let the plant have a bad day

This isn’t about reacting later—it’s about paying attention now.

The growers who protect yield aren’t guessing.
They’re watching the field, reading the conditions, and making the right call at the right time.

Too wet to plant? This episode breaks down what persistent rain and cool soils mean for planting decisions, early-season disease risk, and crop stress in corn and soybeans—and how to stay ahead when conditions aren’t ideal.

Key Takeaways:

• Wet, cool soils increase risk. Expect higher disease pressure, compaction issues, and uneven emergence.
• Conditions matter more than the calendar. Waiting for fit fields can protect yield more than planting early.
• Scouting early changes outcomes. Identifying issues before they spread allows for timely, more effective decisions.
• Think ahead, not just today. Early-season conditions set up in-season stress, disease, and nutrient needs.

Broadcasting from the Landus Research Plots in Farnhamville, the agronomy trio: John King, optimization and procurement lead; Brad Sherwin, technical agronomist data analyst; and Dan Bjorklund, technical agronomy and precision lead, find soybean cyst nematodes and tar spot in fields across the state. Find out how we use over 160 acres of research plots to help the farmers tailor the best products, hybrids, and practices.

Highlights:

•Soybean cyst nematodes are in 90% of soybean fields in Iowa

•Tar spot is reported in six central Iowa counties

•With a dry spring (tar spot being a fungus that spreads via moisture), and a two-week incubation period, tar spot being spotted early is concerning.

•Rootworm beetle has also been reported

•Special in-field report from agronomy account lead, Dave Lemke
