Limit of 3 applications per acre per season. Make no more than two sequential
applications before rotating to another effective fungicide with a different
mode of action.
Limit of 16.5 fl. oz per acre per season. Apply to the base of the plant at
transplanting or in the transplant water. Make no more than three consecutive
applications followed by three consecutive applications of another
effective fungicide with a different mode of action.
Begin applications when conditions first favor disease development and
repeat at 3-to10-day intervals if needed depending on disease severity. Use
the higher rates when conditions favor disease. Do not spray copper when
temperatures are above 90°F.
