White Mold Risk Summary

Risk of white mold has increased as soybeans in the far north have advanced into the flowering stage.

Next two-week risk interpretation

In the next two weeks, conditions are moderately or highly favorable for white mold in the far north. Areas in yellow: scout for white mold mushrooms in fields that are flowering and have a closed canopy. Consider a fungicide application on R2-R4 soybeans if mushrooms are found. Areas in orange: a fungicide is recommended on R2-R4 soybean fields that have a dense canopy. Fields with a higher risk include fields that are: drilled, have a high level of fertility, and had white mold in 2024. Also, consult your agronomist.
