It helps to read what you wrote after sending. This clarifies a question a grower had for me, now that I’ve re-read things. My post should have read “Fire blight remains a serious concern in any orchard that has open blossoms, apply streptomycin at 24 oz/acre plus 1 pint Regulaid (or other similar wetting agent)/100 gallons finished spray within 24 hours of a wetting event to any trees with open blossoms.”
I originally left the Regulaid out of that statement.
