Bud mite (and blister mite) are two strains of a mite species which only occurs on grapevines. They are essentially identical except for the damage they cause by their feeding activities – bud mite feed on and damage young buds, and blister mite cause galling on leaves . The information in this Vitinote focuses on bud mite.

Grapevine rust mite is found in most grape growing areas but is often not a problem unless the overuse of chemicals affects populations of predatory mites and insects. It causes damage to leaves and bunch stems.

Spring control of rust mite

  • Date: 2005-01-01
  • Author: Cooperative Research Centre for Viticulture

If rust mite activity was observed in the vineyard in the previous season, particularly significant leaf bronzing in the late summer/autumn, control measures for rust mite are likely to be required before budburst in the upcoming season.

Recent research indicates that control of rust mite can only be achieved in a very narrow window in early spring when the mites are exposed during migration from their winter sheltering sites, before leaf expansion provides them with shelter from sprays and before they can lay their eggs.
