Ag Alert! Fire Blight on Apple & Pear Trees
2018 is a bad year for fire blight on pome fruit (apple and pear) partly due to the odd combination of bloom time, temperature and rainfall. In a regular year, most bloom occurs while temperature still below 60° F (minimum temperature required for bacterial infection through flowers).
This year it was delayed but as soon as bloom occurred temperature crossed 60° F mark and rain followed. However, WVU Extension's disease forecast-based spray schedule helped commercial growers keeping disease pressure low. The disease is more widespread at home sites.
