Maryblyt v. 7.1 for Windows: An Improved Fire Blight Forecasting Program for Apples and Pears

Abstract

This article describes updates found in Version 7.1 of the fire blight prediction model Maryblyt, originally developed by Paul Steiner and Gary Lightner. In addition, a brief history of the development of the Maryblyt model is given. The article ends with examples comparing the performance of Version 7.1 to Version 4.3c, the last version that was validated and released prior to its upgrade to Maryblyt 7.0 for Windows. We show that Version 7.1 provides results nearly identical to the previously validated DOS version 4.x.
