Did some searching, and the only I can find on the web so far are sprays and oil sprays to control pear blister mites. I checked permies, and found nothing.
Anyone out there, have any idea of what mother nature does to control these? I have to believe that there is something out there that eats them or some plant aroma that drives them off.
Thanks tons for any input, I am going to keep searching I am working on planting out two fruit tree guilds currently, I have two mature trees, one apple and one pear. Wanna solve this, there has to be a solution short of resorting to sprays.
I remember before I heard the word permaculture, I looked up the organic solution. I had two trees seriously infested with pear leaf blister mite. On one I used the organic spray (I think it might have been sulfur). It helped a little.
On the other tree, I mulched it and sprayed the leaves with alaska fish fertilizer. The leaves turned a dark green and all of the pear leaf blister mites were gone. All gone. I couldn't find any.
Our Orcas pear tree had mites this year, we started spraying the infected limbs with a strong wormwood tea several times a day, mites appear to be gone now. other herbal parasiticides would probably do the same. the leaves are still damaged though, don't know how to fix that.
