Question
we came back from vacation to see miscelaneous dead leaves on my bartlett pear, I pulled one down and it had small webs.
What do I spray with.
This poor tree made it thruogh Katrina, so I don't want to lose it now. thanks

Answer
Sounds like powdery mildew which is a fungus.  

You can use Malathion if you dont mind pesticide.

Or you can use Atomic Grow all natural sold by Crowley Nursery in Sarasota FL.

It works better and will bring back the health of the tree.  May even make it produce more too.

Good Luck either way
