Rovral Brand 4 Flowable Fungicide (iprodione), EPA# 279-9564, READ THE LABEL
Rovral provides effective control of botrytis with protectant, post-infection, and antisporulant activity, but like most botrytis fungicides, it is very prone to developing disease resistance. Apply Rovral at 1 to 2 pints per acre per application during early to mid-bloom, and 1.5 to 2 pints later in the season. 4 applications per season are permitted on the label, but the use of only one application of Rovral per season is highly recommended, as is the use of at least one application of another effective botrytis fungicide. 48 hour reentry interval, 7 days to harvest.
