What sprays do you recommend that I can get locally for peach bottom rot. I have look at your document on peach sprays and cannot seem to find any locally.

Glad you sent in this “Ask an Expert” question. Peach (Prunus persica)-Brown Rot is a problem that can occur in all Prunus fruits (cherry, apricots, plums, peaches, and nectarines) and can even affect apples.
The first step in controlling the fungus that causes Brown Rot is to clean-up the old fruit and twigs on and around the tree. The dried fruit (mummy) need to be picked up and disposed of in the trash. There are probably twigs on your tree that may also be infected, they should be removed and disposed of with the ‘mummies’.
Here is the link to the Pacific Northwest Handbook on Peach Brown Rot:
This paper will explain the life cycle of the fungus that causes Brown Rot and how to control it. Included in the paper is a list of products that can be used on your peaches. Here are three products that are found in that list that can be used in a home orchard. The H at the end of the spray description indicates that the product is approved for home owners.
- Bonide Captan 50 WP may be used in Oregon home gardens at 1 to 1.5 Tbsp/gal water. H
- Hi-Yield Captan 50 W Fungicide may be used in Oregon home gardens at 1 to 1.5 Tbsp/gal water. H
- Spectracide Immunox at 0.5 fl oz/gal water. May be applied up to the day of harvest. Do not use more than seven (7) times per season. H
You should be able to purchase these products at any of the larger local Benton County nurseries.
Be sure to follow the instructions on the label of the product you purchase.
