Features
  • One of the most destructive diseases of stone fruits (peaches, plums, cherries, apricots). Caused primarily by the fungus Monilinia fructicola
  • Symptoms start as blossom wilt in spring. Flowers turn brown and shrivel, often staying attached to the branch by a sticky, gummy substance
  • As fruit ripens, it develops small, soft tan spots that rapidly enlarge. In wet weather, these spots become covered in fuzzy, grey-to-tan spore masses
  • Infected fruit continues to rot until it becomes a shriveled, hard, black 'mummy'. These mummies often remain hanging on the tree through the winter
  • The fungus overwinters in mummified fruit on the tree or ground and in twig cankers. These sources release spores to start new infections in spring
  • Infection can spread from a single fruit to an entire cluster where fruits touch. Thrives in warm, humid, and rainy conditions near harvest
  • Insect damage from plum curculios or birds provides entry points for the fungus, greatly increasing the speed and severity of an outbreak
  • Infected twigs may develop small, sunken cankers that can eventually girdle and kill the branch tip
  • Prevent by removing and destroying all rotted or mummified fruit from the tree and the ground. Prune out and burn any infected twigs or cankers
  • Apply organic fungicides like sulfur or potassium bicarbonate starting at bloom and again as the fruit begins to ripen, especially during rainy periods
