Sulphur is not really good for human consumption, so I would be very wary of using it on fruit if you are going to collect the berries. If, like ours the berries have been picked then perhaps.
Usual reason for mildew is dryness at the roots. Try watering the bush, even if it has rained. Or spray with a 9 parts water to one part milk solution. That has been known to deal with Mildew and at least it is not toxic to us.
