“When is the best time to spray soybeans with fungicide?”
Data shows that soybean fungicide applications give the best return at the R3 growth stage.
What to look for: A 3/16 inch pod starting to develop in the four top nodes of the main stem.
Soybeans tend to stay in this stage for 7-8 days before moving past the optimum fungicide window.
