In the 7 years since I planted my apple orchard, this has been the worst for FB. I really dropped the ball on spraying this spring b/c CAR was almost non-existant due to unfavorable weather conditions. I had to spray for CAR only once this spring when in years past I have had to spray 3 to 4 times in April and May. All that said to explain why I didn't spray for FB.
I pruned some out when it first appeared at blossom time but then I had to go out of town for work. Yesterday I spent nearly all day cutting FB out of most of my trees. Pretty sad. I burned a pile of limbs the size of a VW Beetle.
I got out my backpack sprayer and went to mix up a couple gallons of Fertilome (streptomycin) spray and after reading the label further, it says not to spray when fruit is visible. At this point I'm willing to sacrifice my crop to save the trees. I wonder if the fireblight will continue to spread from this point on? I don't know b/c I've never seen it this bad.
I'd like to hear your thoughts. Thanks,
