Peach Leaf Curl

Peach Leaf CurlPeach leaf curl is a common disease caused by the fungus Taphrina deformans.  Besides peaches, susceptible plants include nectarines and almonds.

The peach leaf curl fungus spends the winter in the bark and buds of its hosts.  It enters new buds as they begin to swell and open in the spring, spread by rain and dew.  Not surprisingly, wet weather creates a situation ripe for trouble with this disease.



  • Pale or pinkish new leaves, depending on tree variety.
  • Thick, puckered, curled leaves or portions of leaves.
  • Leaf drop.
  • Stunted twigs.
  • Poor fruit yield.
  • Raised, discolored spots with no fuzz on fruit.
  • Gradual tree death.


Peach Leaf CurlTreatment

Trees that are showing symptoms of peach leaf curl cannot be treated until the following spring.  In the meantime, thin the fruit and keep the tree healthy with adequate water and fertilizer.

Early in the spring, after the tree has been pruned but before the buds begin to swell, spray the tree thoroughly with the appropriate fungicide (organic growers can use copper).  Make sure you cover the entire tree on all sides, from the trunk to every small twig.  Be prepared to repeat the treatment if it rains.  This process will probably need to be repeated in future years.


Peach Leaf CurlPrevention

The best prevention is to purchase fruit tree varieties resistant to peach leaf curl.  Still, susceptibility can be reduced with attention to water and fertilizer.  A good rule of thumb is to measure a shoot to see how much the tree grew the previous year.  If the shoot is a foot long or shorter, fertilize the tree.  Do not overdo, however, as excess growth tends to be soft and disease-prone.

Brown Rot
The Garden

Brown Rot

Brown RotBrown rot is a serious disease of fruits and almonds caused by fungi Monolinia fructicola and Monolinia laxa. The fruits most susceptible to the fungus are:

  • Peaches.
  • Nectarines.
  • Plums.
  • Apricots.
  • Cherries.
  • Almonds.

However, apples and pears are infected with brown rot on occasion.

The fungus grows and multiplies rapidly in wet weather, entering plants through wounds. It survives the winter in twigs and dry, shriveled pieces of fruit called mummies.



  • Small, elliptical cankers on twigs, generally oozing.
  • Gray, fuzzy masses of spores on branches or flowers.
  • Brown, wet spots on blossoms.
  • Blossom drop.
  • Brown or gray fuzz on fruit.
  • Mummified fruit.


Brown RotTreatment

Cankered twigs should be pruned out during the summer.

Blossoms can be treated for brown rot starting when the first pink shows in the unopened bud. Treatment should continue through the spring if the weather is wet. Fungicides are typically used, but organic growers can spray with sulfur or copper. Spraying with organic milk also shows promise at this point in time.

Fruit that is visibly affected with brown rot must be destroyed to prevent the spread of the disease. Fungicides can be applied to the unaffected fruit as soon as it begins to ripen.


Brown RotPrevention

The first step in preventing brown rot is to remove potential vectors of the disease:

  • Destroy wild plums growing near the orchard.
  • Water trees at the base so that the leaves do not get wet.
  • Control insect pests.
  • Pick up all fruit laying on the ground under the trees.

Proper pruning is also an important part of preventing brown rot. If air and light can reach all parts of the canopy, fungal diseases will have a hard time gaining a foothold.
