Machine-Vision Technology Shows Promise to Reduce Herbicide Use

Farmers and land-managers seeking to reduce their herbicide applications now have another promising option via machine-vision technology. That's the summary from a recently published research article in Weed Technology.

"Our research showed that, on average, this technology's targeted sprays saved a range of 28.4 to 62.4% on postemergence herbicides compared to traditional broadcast applications," says Tristen Avent, University of Arkansas, Senior Graduate Assistant in the Crop, Soil, and Environmental Sciences Department, and corresponding author of the study.

"In addition to significant opportunities to lower herbicide costs and improve profits, our research also showed that the targeted applications from machine-vision technology can be utilized to provide some soybean health benefits and improve ."

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
