Abstract
Development of a blossom blight prediction system for the Appalachian fruit growing region is based on the application of existing fire blight risk assessment schemes dealing with degree days (Illinois), degree hours (California) and potential doubling of the causal organism, Erwinia amylovora, prior to and during bloom (England). All three methods are related to temperatures above 65°F (18.3°C). For Kearneysville, West Virginia, temperatures during 1984 bloom were between 50–65°F (10–18.3°C), rainfall totalled .87 inches (23 mm) during 4 days, and light fire blight occurred in certain areas.
In 1985, temperatures were between 60–85°F (15.6–29.4°C), there was no rainfall and moderate to severe fire blight occurred in most areas.
In 1986, temperatures were again under 65°F, and without rainfall there was practically no fire blight.
