1-Late dormant/delayed dormant (pear)
Late dormant/delayed dormant

Of high concern at late dormant/delayed dormant is pear psylla. Oil application would be the first IPM strategy, applied as soon as adults are present, usually the first nice warm day in April. If oil application is impractical, use an effective insecticide when adults are present. A high rate copper application for fire blight is also a good IPM strategy at this time.
