The Problem

Brown Rot

Monilinia fructicola

Brown rot is a problem mostly of stone fruit such as peaches and nectarines. 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 shedmillions of spores. These spores will shed at the slightest disturbance.


Flowers of fruit trees wilt and turn brown. Flowers will often stay attached to the tree. Brown spots appear on fruit which expands to a powdery mass of tan coloured spores. The fruit quickly rots, and if left on the tree will dry and turn into a “mummy”.
