| Abstract: | At Long Ashton Research Station serious outbreaks of fireblight (caused by Erwinia amylovora ) occurred on apples in 1978, 1980 and 1982. and on pears in 1979, Mid-season and late-flowering cider apple cultivars were particularly affected. On cider apple, outbreaks were associated with years of profuse blossom coinciding with unusually warm temperatures during bloom. Spread of infection between hosts, including hawthorn and cotoneaster, was undoubtedly important. These and other factors underlying the outbreaks are discussed. |
