Brown rot is one of the most common and serious diseases affecting peach fruits. It is caused by the fungus Monilinia fructicola, and can also infect flower blossoms and shoots. The disease begins at bloom. Infected flowers wilt and turn brown very quickly. Shoot infections (usually from flower infections) result in small (1 to 3 inches), gummy cankers, which provide the source of infection for fruit rot. Spores from infected flowers and cankers infect healthy green fruit during long wetness periods. Infected, fruit remain attached in the tree and provide an additional source of spores for more infections instead of dropping off in a normal fashion. Some infections only show when fruit begins to ripen.
Fruit rot starts with a small, round brown spot, which expands to eventually rot the entire fruit. Infected fruit turns into a mummy on the tree. The fungus survives the winter on fruit mummies (on the tree and on the ground) and twig cankers.
Prevention & Treatment: Collect and remove diseased fruit from the tree as it appears. Collect and dispose of any diseased fruit on the ground. In the fall remove all dried fruit mummies from the tree, since this is where the fungus survives the winter. During pruning in winter, remove all cankerous parts of the tree.

Spray during full bloom and two subsequent sprays at 10 to 14 day intervals to prevent infections of flowers and young fruit. Fungicides are also required when fruit ripens. It is important to begin spraying in 7 day intervals (typically, three times until harvest) when fruit turns color from green to yellow and red. Starting a spray program when rotten fruit is already evident will result in poor disease control. Select a fungicide containing captan, or propiconazole that is labeled for use on peaches. See spray schematic for peaches below. These fungicides are only effective if a complete and thorough coverage of the tree(s) can be obtained. See Table 1 for examples of brands and specific fungicide products. Always apply all pesticides according to directions on the label. There is a minimum of a one day pre-harvest interval for these fungicides (that is, the time between spraying and harvesting).
Though products are available at gardening stores for homeowners, many gardeners are not inclined to use pesticide applications for home fruit production. Instead, hobbyist gardeners may use bags to protect fruit from pests and diseases. Clemson University has tested and is promoting the use of specialty bags that, if used properly, allow for production of high quality fruit with very little pesticide input. The bags are recommended for use in a three step fashion: (i) properly take care of your trees to minimize tree stress (ii) protect your fruit from pests and insects between bloom and the day of bagging and (iii) enclose nail-sized, green fruit (typically 3 weeks after bloom) with a specialty bag to be removed at harvest. For purchase information and use instructions please see: Clemson Fruit Bags or simply google this page using the key words “Clemson Fruit Bags”.
Although all varieties can be infected, there are some (such as ‘Contender’) that are very tasty and do have some resistance. DO NOT GROW NECTARINES. They are VERY susceptible.
