Number on dial: Rust infections per foot of row
Green: Below spray threshold
Yellow: Above spray threshold for DMI fungicide, but not for strobi.
Red: Above spray threshold for strobi fungicides
If the needle stays in the green zone, there will be no yield loss from stem rust.
When treating with a triazole, apply it when needle first crosses into the yellow zone. When treating with a strobilurin, apply it when needle first crosses into the red zone.
