    My tree has pear leaf blister mites and it is getting pretty ugly. Would anyone know if there is an effective spray I can purchase and use myself or would I need to hire a professional tree person to come out and spay?

    I was just Googling around the other day on these pests. Most commonly recommended treatment is dormant spraying with Oil and Sulphur, although one article I read mentioned that Cygon seemed to be more effective after a conducted trial of both products. The nice thing about using Cygon is it can be applied to the trunk with a paint brush, very easy and no spraying required. The not so nice thing about Cygon is it really stinks and is reasonably toxic if not handled properly. I found a link to the article I read. Good luck Jim.

    Thanks for the suggestion! Hopefully I can find it here in No. Utah and it is affordable. I will definitely look into that but I guess I will have to wait until pre-Spring season before it begins to get leaves again.

    I have the same problem with my pear trees. :(

    You want to try this sulfer sprays in the fall (after production and before leaves fall)
    and neem oil in early spring.
    Check this link for detail:

    I would also rake up all fallen leaves, bag them securely and put in the garbage. Do not compost!
