Apple scab and rust infection period May 10-11

For the record, an apple scab and rust infection period was recorded at our AREC May 10-11: 18 hours wetting with 0.73 inches of rain at 60-64°

With predicted temperatures this week, fire blight risk is low to moderate May 13-15, then quickly returns to an infective level for late bloom May 16-17. For practical purposes, that will affect mostly the York Imperial and Rome Beauty cultivars, but check blocks carefully because Golden Delicious, Idareds, and others still have scattered pockets of susceptible bloom.
