The rate for Bonide Mancozeb Flowable with Zinc Concentrate is not set per gallon but per area, per he product label on grapes East of the Rockies you would use 0.88 to 2.35 fl oz per 1000 sqft. You would apply in sufficient water to provide thorough coverage. Typically 1 gallon can cover 1000 sqft but it could take more depending on equipment used and walking speed.
