| When we studied the rates of deaths of vines in infeced blocks, we were able to provide growers with some valid data to use when estimating future costs of vine deaths. Using the information collected on the rate of vine deaths in infected blocks and calcuating the cost of vine replacement and crop loss from not replacing vines in the calculation spreadsheet, we have provided a tool which allows the vineyard manager to calculate, for a future date, whether it would be economic to replace vines or not. This calculation is designed as a guide only and allows growers to enter their own data and calculate the potential costs without having to worry about the details of the mathematics. |
