Hi All,
I've been reading a bit of what's going on
regarding fire blight with great interest. For the nine years that I have
been growing fruit trees I have had very little incidence of fire blight.
The little fire blight that I had was in a few of my quince trees. I
haven't been very diligent about spraying my trees either, I might add. As
a matter of fact, one of my resolutions this year was to be more
proactive/intelligent with my spraying. I did my dormant oil and ferbam
and continued with imidan (thank you Harvey Lisle) and manzate. I, for the
first time, also applied streptomycin with my imidan/manzate spray.
Perhaps I applied the streptomycin too late, perhaps this year was perfect for
the growth of the fire blight bacteria or perhaps I was too lazy regarding
orchard sanitation. Either way, I have been walloped with a bad dose of
fire blight on my seckel pears and a few apple trees. I have cut out as
much dead/diseased wood as possible and have sanitized both the wound/blade with
rubbing alcohol. The bacterium progresses. At this point what should
I do? A local professional orchardist said to not spray anymore
streptomycin as I would be wasting money. He said to let the fire blight
take it's course and prune it out this winter. What is the recommended
course of action? Is it too late to apply streptomycin? I appreciate
any and all advice. Regards, ken
