Peach Tree Brown Rot

Anonymous added on June 4, 2011 | Answered

We have five Peach trees - Three Southern and Two Californian species. One of the southern species has Brown Rot? The fruit is abundant and about two weeks from harvesting time. We have cut off as much of the damaged fruit and twigs as possible. Also, some of the leaves are withered and falling. What causes this? We thought it may be due to the increased amount of rain. We do not spray the trees. The other four trees are still in the green stage. No evidence of damage yet. What do you advise? We have collected about 70 lbs of damaged fruit. Any help would be much appreciated.

Brown rot is one of the most important diseases of peaches. To minimize brown rot spore populations, thin down or remove all remaining fruit from the tree. Fungicides are recommended as a preventative measure and should be applied during preharvest, as the fruit begins to color. Additionally, postharvest treatments, such as hot water treatments and chlorine dips, can sometimes be beneficial.
