Transplant soil drench: Immediately after trans- planting, apply
3.4 fl oz of transplant solution per plant. Soil incorporation:
Apply in a 9-in. band and incorporate 6 to 8 in. deep before
transplanting. Note: Omega may delay harvest; see label. Do
not apply to turnip grown for roots.
Do not make more than 2 sequential applications before alternating
to a fungicide with a different mode of action. Addition of
an adjuvant may improve performance (see label for specifics).
Make applications on a 7 to 10 day schedule. Do not apply
more than 39.5 fl. oz/acre per crop growing season.
Must be tank-mixed with another fungicide active against
Phytophthora blight. Do not make more than 2 sequential
applications before alternating to another effective fungicide
with a different mode of action. Do not make more than 5 apps/
season. Do not apply to turnip greens or roots.

of 7 applications can be made per season. Do not apply to
turnip greens or roots.
Apply when weather is foggy as a preventative. Do not apply
to plants under water or temperature stress. Spray solution
