Monilinia fructicola (Stonefruit, Cherry, Blueberry)

What is Brown Rot?

Brown Rot of Stonefruit, Cherry & Blueberry

Brown rot is a destructive disease of stone fruits. The fungus overwinters in mummified fruit which has either fallen to the ground or is still attached to the tree. Cankers on stems and spurs are another source of disease spores. At blossom time the fruiting bodies of the fungus develops toadstool-like structures which shed millions of spores. These spores will shed at the slightest disturbance.

Brown Rot of Citrus

In citrus, brown rot is caused by various Phytophthora species, which are soil-inhabiting fungus-like pathogens. You can find out more about how to control citrus brown rot here.

Symptoms

Fruit develops circular areas of brown rot, that widen and spread over the fruit as it approaches maturity. Brown Rot has a distinctive smell.

Severely affected stonefruit can develop a greyish fuzz of spores.

Stonefruit trees may sometimes exude gum from cankers that form on branches.
