Peach Silver Mite

Peach silver mite damage

Hosts:  nectarine, peach

  Worm-shaped microscopic mites called eriophyid mites; related to blister and rust mites.  They overwinter as females in buds, just beneath the outer scales; they crawl to new leaves after budbreak.

  Heavy feeding causes “silvering” of leaves, reduced fruit size, and premature fruit drop.

  Because these mites are so small, they are difficult to see with a hand lens, which makes monitoring difficult.  Starting in mid summer, check the leaves for the silvering symptom.

Treatment Threshold:
  No threshold determined.

Degree Day Model:

Management Considerations:
  Moderate populations are a good food source for predatory mites, especially early in the season. Peach cultivars vary in susceptibility to the mite: ‘Red Haven’ is a poor host while ‘Elberta’ is a good host.
