What causes scabs on peaches?
Peach scab is a disease caused by the fungus Cladosporium carpophilum (Figure 1). The pathogen can infect twigs, leaves, and fruits, where it can cause lesions that can affect fruit quality, marketability, and in extreme cases can cause cracking of the fruit and premature fruit drop.
Why does my peach have red spots?
Red spots on a peach tree are caused by overwatering combined with poor drainage. But red spots can also be caused by chemical toxicity or lack of nitrogen. peach trees are also vulnerable to rust and leaf curl that can cause red spots on the leaves before they start falling from the tree.
Why does my peach have white spots?
Answer: This whitish tissue may actually appear on the pit and/or in the pit cavity (area inside peach around pit) of a ripe peach. It is called callus tissue (undifferentiated cells). It is not a fungus, bacteria or other type of disease. It is naturally occurring, and it is not harmful.
Why are my peach blossoms turning brown?
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.
What causes fruit rot?
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 wet periods.
What is the fungus that grows on fruit?
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.

What causes a peach to have a spot on the bottom of the fruit?
Bacterial spot is an important disease of peaches, nectarines, apricots, and plums caused by Xanthomonas campestris pv. pruni. Symptoms of this disease include fruit spots, leaf spots, and twig cankers. Fruit symptoms include pitting, cracking, gumming, and watersoaked tissue, which can make the fruit more susceptible to brown rot, rhizopus, and other fungal infections. Severe leaf spot infections can cause early defoliation. Severe defoliation can result in reduced fruit size, and sunburn and cracking of fruit. Early defoliated trees are reduced in vigor and winter hardiness.
What causes peach scabs on trees?
Fruit symptoms of bacterial spot may be confused with peach scab, caused by the fungus Cladosporium carpophyllium, however scab spots are more circular, have a dark brown/greenish, fuzzy appearance, and do not pit the fruit surface, although skin cracking can occur.
What chemicals are used to treat bacterial spots on peaches?
Compounds available for use on peach and nectarine for bacterial spot include copper, oxytetracycline (Mycoshield and generic equivalents), and syllit+captan; however, repeated applications are typically necessary for even minimal disease control.

Severe leaf spot infections can cause early defoliation. Severe defoliation can result in reduced fruit size, and sunburn and cracking of fruit.
