I also need a fungicide that doesn't leave a residue. Would cupro 5000 wash off easy? need a fungide for black rot on grapes and late rot on blueberries,they rot from the inside and just drop when ripening. i would like to stay with one product if possible.
Yes, Cupro 5000 DF Fungicide is labeled for fire blight on flowering pear trees. Yes, this will wash off. We would recommend using Fertilome Triple Action. It is labeled for use on grapes and blackberries. The mixing ratio is 1 fl. oz. per gallon of water. This will go on clear and will not leave a residue.
