Determine the relationship between hang time/crop maturity and the manifestation of fruit rot during ripening of Niagara grape. 3. To articulate the costs of new spray guidelines and/or the economics of increased risk associated with high brix Niagara. This proposal addresses National Grape and Wine Initiative priority 4, to improve integrated pest/pathogen management.
