Furthermore, removal of remaining fruit after final picking separates the practice of removing mummies from spring pruning. Alternatively, direct a sprayer nozzle downward so that thinned fruit receive some fungicide. In spring, monitor for blossom infection and prune out any cankers and infected shoots.

Their presence requires that blossoms be thoroughly protected with fungicide sprays during wet periods.
Fungicides are to be applied prior to fungal infection that occurs during rain periods.
Here is a table describing the relative effectiveness of peach fungicides for commercial fruit producers. Captan 50W 1 lb. Captan 50W 4 - 6 oz. Combinations involving Benlate or Topsin-M may become ineffective for scab or brown rot control if resistance to these fungicides develops. If resistance is suspected, switch to a fungicide program not involving Benlate or Topsin-M until the fungus has been tested for sensitivity.
