Stak’d Against Corn Rootworm: A New Triple-Threat Trait for 2027- Durastak™

Stak’d Against Corn Rootworm: A New Triple-Threat Trait for 2027- Durastak™

This Cornelius Seed podcast episode focuses on the evolving challenge of corn rootworm and what’s new in managing it, featuring Brian Walsh with GreenLeaf Genetics. Walsh explains rootworm lifecycle, how western rootworm and northern rootworm have reduced the effectiveness of crop rotation, and why multiple modes of action are important for resistance management. The discussion introduces Syngenta’s Durastak™ (and Durastak Viptera™), an industry-first triple Bt protein approach for below-ground rootworm control, positioned for moderate-to-high pressure fields, with plot testing in 2026 and a full commercial launch in 2027 via the Cornelius portfolio. They compare Durastak™ to Duracade™ and share data showing improved root protection, standability, and about a 10-bushel yield advantage under moderate-to-heavy pressure, emphasizing multi-year trait rotation and matching genetics to fields. 00:00 Resistance Management Basics00:44 Podcast Intro and Guest02:46 Rootworm Problem Overview03:57 Rootworm Lifecycle and Evolution07:11 What Is Durastak™08:46 Duracade™ vs Durastak™ Positioning11:46 Triple Bt Proteins Explained15:24 No Silver Bullet Field Management17:58 Trait Stack Pest Control Chart21:40 Root Protection and Yield Loss23:58 Cry Proteins vs RNAi Rotation27:13 Yield Advantage Data29:13 Multi Year Rotation Strategy33:41 Wrap Up and Final Advice

2026 Corn Emergence Check-In: Crusting, Cold Injury & What to Scout For

Lead agronomist Craig Allaman joins host Juan for a season check-in on corn and soybean emergence across the Cornelius footprint. After a challenging spring marked by narrow planting windows, sporadic heavy rains, and an unusual stretch of cool nighttime temperatures, Craig breaks down what's actually happening underground — and what growers should be watching for right now.

2026 Planting Season Update: On-the-Ground Reports from Iowa & Wisconsin

Host Juan checks in with three Cornelius Seed District Sales Managers who also farm in their own territories — Brad Grandgeorge (Central Iowa), Joe Braudt (Southwest Wisconsin), and Mike Lund (Southwest Iowa) — for a real-time planting season update. The conversation covers planting progress, field conditions, and the challenges of a cool, wet spring. Topics include soil fitness, crusting concerns, emergence watch-outs, the value of seed treatments in cold conditions, cover crop strategies, biological inputs, and the importance of patience over rushing to beat the neighbors. Each guest shares what good operators are doing right this spring and what agronomic lessons 2026 is already teaching.0:00 – Intro & Welcome0:33 – Brad Grandgeorge | Central Iowa (Wright County)1:35 – Planting progress & field conditions in Central Iowa2:58 – Early emergence & crusting concerns4:21 – What good operators are doing this spring5:16 – Planter prep tips & precision equipment checks8:23 – Joe Braudt | Southwest Wisconsin (Grant County)9:10 – Cold, wet conditions & delayed planting progress10:37 – Cover crops, rye planting, and soil moisture15:58 – Seed treatments & seedling disease watch-outs17:44 – Agronomy lessons from a tough spring start19:52 – Biologicals & non-GMO corn strategy22:01 – Mike Lund | Southwest Iowa (Pottawattamie & Shelby Counties)22:24 – Strong conditions in Southwest Iowa & planting progress26:07 – Final advice: don't rush, stick to the plan

Planting Fundamentals: Patience, Soil Fit, and the right Seed Depth

On the Cornelius Seed Podcast, host Juan is joined by DSM Tyler Sprain (north central Iowa) and RSM Cliff Lane (west central Illinois) to discuss what matters most as planters start rolling for corn and soybeans. They emphasize patience with volatile spring weather, avoiding cold-wet conditions, and watching soil temperature trends (around 50°F) along with tillage and residue effects. Key fundamentals include equipment readiness and maintenance, driving appropriate speeds, getting out to check behind the planter, and prioritizing consistent seed placement—especially planting depth (measuring where the seed sits, not just the trench bottom). They note early soybeans can be a “free” yield opportunity if conditions are fit and seed has a strong treatment package, and they discuss soybean population, emergence variability, and avoiding rushed replant decisions. The episode closes with advice to be safe and focus on small details that stack up to protect yield.00:25 Meet The Guests01:53 Patience And Soil Temps04:06 Corn Vs Beans Timing05:36 Cold Dry Vs Cold Wet08:34 Stand Basics And Depth10:24 Get Out And Check11:52 Maintenance And Speed15:57 Tools And Calling Help17:22 Early Soybean Advantage20:15 Soybean Treatment Packages21:05 Planting Depth Basics21:46 Population Sweet Spots24:53 Replant After Hail Frost27:15 Slow Emergence Decisions29:03 Measuring True Seed Depth32:15 Weather Gut Check37:04 One Key Planter Tip39:15 Fundamentals Closing Wrap

Unlocking New Yield Potential with Pivot Bio's Nitrogen-Fixing Solutions

In this Cornelius Seed podcast episode, host Juan talks with Pivot Bio’s Nick Fischer and Alex Obermier about Proven® G3, a third-generation nitrogen product using nitrogen-fixing microbes that continue fixing nitrogen in the presence of synthetic N and continuously release it to the plant. They explain how G3 adds two methylotrophs- one to stimulate bigger roots and one to make nutrients more available- along with results from 300+ full-field trials showing more frequent yield increases versus prior “yield parity” outcomes. The conversation covers new delivery options (on-seed, liquid in-furrow, and a new dry planter-box formulation), mixing and planting windows for the dry product, storage considerations, compatibility guidance, and how the microbes attach to roots, feed on plant exudates, and produce nitrogen through roughly VT-R1.
