trying to save our pear trees!

Asked April 29, 2019, 11:02 AM EDT

We have two fruit bearing pear trees that used to produce bucket fulls, until about 4 years ago. The past two years, I treated with Bonide Fruit tree spray, as recommended, but still lost all leaves by end of July. This year, in hopes to get an upper hand, we pruned early and sprayed about 3 weeks ago. There are much more pears buds swelling than last year, but there is still something attacking the leaves!!. Please help me salvage! I am REALLY hoping this is not a lost cause! Should I spray with something else? Assuming I should go ahead and cut or snip off as many infected leaves that I am able, .... Can I spray again? if so, what do you recommend?

Hello,

Growing backyard fruit trees can be very challenging, especially in our mid-Atlantic climate with high humidity. Pear trees are susceptible to plant disease caused by fungi and bacteria as well environmental stress. We had a late frost which affected buds as they were expanding. A combination pesticide spray will help control insects and some fungal diseases. Pears get fire blight caused by a bacteria. Management of fire blight consists of pruning when weather is very dry, in early summer, and pruning back 10-12 inches below branches that were affected and discarding prunings in the trash. Control of fungal leaf spots and fruit spots is usually by use of fungicide sprays. Fungicide sprays need to go on right after bloom.and then again about 10 days later. Do not spray when bees are active
We have a fact sheet on home fruit that gives some basics: http://extension.udel.edu/factsheets/home-orchard-production-apple-pear-and-stone-fruit-disease-mana... There are some resistant cultivars of various fruit trees.

Thank you for contacting Cooperative Extension,
