Tar Spot and Fungicide Survey

By Daren Mueller

Planting is nearly here and folks are busy – but we are hoping you can help us with a tar spot and fungicide survey. This survey is the creative component for a Masters of Agronomy student, Kelsey Richie. She is hoping to get a better understanding of how tar spot may affect farmers' decisions around fungicides. There are two surveys, one for farmers and one for crop specialists. If you could spare some time to complete the survey, it would be greatly appreciated.

A cold snap swept across west central Minnesota and eastern South Dakota, bringing frost, fog, and temperatures dipping into the 20s—raising urgent questions about early crop damage.

Pioneer Agronomist Eric Rice breaks down what those overnight temperatures could mean for emerged corn and soybeans, how to assess frost injury, and why patience is key before making any replant decisions. Learn the critical differences between corn and soybean growing points, what cosmetic vs. serious damage looks like, and how last week’s high winds may also be influencing what you’re seeing in the field.

Watch for:

• Frost thresholds for early-season crop damage

• Why corn may be more resilient than it looks

• Soybean growth stages and frost susceptibility

• How to evaluate brittle stems and discolored tissue

• Why waiting 4–5 days before assessing stand loss matters

• When to contact your local Pioneer agronomist or sales representative
