Asian Pear Tree help #872289

Asked June 09, 2024, 1:15 PM EDT

I have an older Asian Pear tree that produces a lot of fruit every year. The last 5 years or so my pears end up having worms (probably codling moths) I garden organically. In mark I stray with a mineral oil spray. I’ve tried wrapping the trunk and natural concoction that supposedly attracts the moths, but nothing works. Can you please help?

Hi and thanks for your question about coddling moth in your pears. The best solution we have found in our home orchard is
Cyd-X which is a virus that only attacks coddling moth. It needs to be sprayed now, but is quite expensive so if you can share with a neighbor it will help. It also lasts years in the refrigerator so it's kind of an investment if you don't want to deal with the larvae in the pears. Of course you can always just cut them out...

Here's the official information with other methods of control.

Thanks for your info. I did buy 6oz of Cyd-X. (Yes very expensive). Since I missed spraying after the blossoms fell, when should I spray now? I have a lot of questions. I have 2 Asian Pear trees and one apple. The directions on the Cyd-X says 1/2 oz to 3 oz per acre. The liquid stated is for orchards and call for 50-100 gallons. I have a quart and a half sprayer. Should I put just a few drops in and how often should I spray. If someone knows about what I should do, please call me at<personal data hidden>. Thanks Janice Avidan

Hi Janice and thanks for your Cyd-X questions. My husband, who does our spraying says put about 10 drops in your sprayer and spray tomorrow after the rains are done. Then spray again 10 days later. You can also do one more 10 days after that and that should be enough. You might have to mix several times to get enough for all 3 trees, as you need to coat the leaves and new fruitlets both tops and bottoms each time.

Good luck and thanks for doing the natural thing!

Hi Rhonda, you answered my request for help about my Asian Pear tree back in June. I’m looking at being prepared for next year. I’m wondering when your husband starts spraying? It looks like it’s as early as after blossoms come? Do you have any more advice about this?

Hi Janice and thanks for your further question about when to begin spraying your pear and apple trees. First, make sure you spray horticultural oil this winter after you have done winter pruning and before the buds break. This will help with all kinds of insects including codling moth.

As to spring Cyd-X, he looks at the following website which tells when codling moth emerges and when it says 10% he does his first spray. There are a lot of other pests listed, but he looks for codling moth. https://uspest.org/risk/models

It's a little time consuming to keep track of, but worth the effort to have great fruit!
