Brown Rot on Peaches

All of the rain we are receiving this year is beginning to cause problems with diseases on peaches. Brown rot can be a devastating disease on peaches and can quickly spread to all of the fruit on the tree. The picture shows brown rot developing on fruit that has just recently dropped.

In order to prevent brown rot from consuming all of your peaches, a fungicide will need to be applied on a weekly basis beginning approximately 4 weeks preharvest. If rainfall is heavy during this time then the interval should be shortened even further. Also if sulfur is being used the interval should be shortened. Removing infected fruit will also help reduce inoculum.
