Prepare to battle common soybean diseases in 2022

INDIANAPOLIS — Diseases like root rot, stem rot and sudden death syndrome can result in yield losses of 40% or more in soybeans.

Scouting fields is important, but the best defense is to use the correct seed treatments and fungicides, along with good timing, according to agronomists at Corteva Agriscience.

“The best way to avoid having sections of fields fall victim to soilborne diseases is to try and prevent the diseases in the first place,” said Nathan Wyss, market development specialist for Corteva.

“Focus on seed treatment with fungicide. It’s not worth it to skimp on seed treatments to save costs. You’ll pay for it down the road with reduced yields.”

Fungicide seed treatments offer broad protection, giving seedlings a strong start. Adding an insecticide to the treatment helps prevent insect feeding, which creates an entry point for disease.

Selecting soybean varieties with SDS resistance is important to managing the disease.

Improving field drainage and reducing compaction can also help limit disease pressure.

Lastly, planting the most problematic fields last allows for warmer soil and decreases the chances of disease.
