Beware of the potential for heavy rain
Do not make broadcast applications to transplants

8. Strategy Apply prior to weed emergence
Apply to seeded crop prior to emergence, or apply as a banded spray between rows after crop emergence or transplanting.

9. Strategy Should be able to obtain same rate of ethalfluralin (Curbit).
Command should enhance activity of annual grasses (expect Texas panicum), sida, croton, lambsquarters.
Buffer restrictions are identical to Command applied alone
Be aware of carryover from clomazone
