Fire blight risk on Friday

By Terence Bradshaw

This is just a quick word of warning that the heat, peaking on Friday, will allow for buildup of the fire blight bacteria to infective levels in orchards where the pathogen is present. While most or many apples and especially pears are past petal fall, any that are still in bloom should be treated with streptomycin (or Serenade / Double Nickel if organic) any time between now and early Saturday.
