2012 Frost Damage
Kevin Martin, Extension Educator, Business Management
Lake Erie Regional Grape Program
A perfect storm of conditions hit the Lake Erie Region to maximize the economic impact of the weather related events this spring. Historically high bulk juice prices, high crop potential and ten frost or freeze events resulted in a substantial decline in the expected value of the crop. Crop insurance, potential disaster payments and modified production practices will lessen the negative impact somewhat.
