Whatis causing blistery bumpsonthe leaves of our walnut tree?
It’sdownto a tiny mite, Eriophyes tristriatus. The damageis largely cosmetic, and it’s not considered worth spraying— by the time bumpsappear the mites within have natural protection. Amiticide used early in the season might have worked, but unless the tree is very small it would not be practical, plus such sprays are fairly toxic. Leafroller caterpillars, aphids, codling moth and lemon tree borer attack walnuts too, but are also regarded as minor pests.
