Soybean Seed Treatment | Jenny Brhel | April 24, 2026

Why It Matters

By trimming unnecessary seed‑treatment and seeding costs, producers can protect thin margins and remain competitive despite high input prices and soft soybean markets.

Key Takeaways

• Nebraska research shows seed treatments can save $13.5‑$28 per acre.
• Insecticide seed treatments rarely boost yields; use only for specific pests.
• Fungicide treatments help in cool, wet soils or disease‑prone fields.
• No yield difference found among untreated, chemical, or biological seed treatments.
• Reducing seeding rates can cut costs without significant yield loss.

Summary

Nebraska Extension and local producers released new on‑farm research evaluating soybean seed‑treatment economics as input costs rise and margins tighten.

Across 11 site‑years (2023‑2025) the studies found growers could save $13.5‑$28 per acre by reducing or eliminating seed treatments. Insecticide treatments showed little to no yield benefit in 14‑state trials, while fungicide applications only paid off in cool, saturated soils or fields with a history of seedling diseases.

As researcher Jenny Brhel noted, “Insecticide seed treatments should be an exception, not the rule,” and field data showed no yield difference among untreated, chemical, or biological treatments. Additionally, trials confirmed that lowering seeding rates to 90,000 seeds per acre typically reduced yields by at most two bushels.

The findings give Midwest growers a data‑driven path to cut expenses—by matching treatments to risk, using fungicides selectively, and considering lower seeding rates—potentially improving profitability in a low‑price market.

Original Description

Input costs remain high and margins are tight for many producers. So, every decision counts. New on-farm research from Nebraska Extension and local producers suggests there may be opportunities to trim costs including a closer look at soybean seed treatments.
