Problem Solver: Problem
Spider Mites (Rose)

Problem Info

Leaves are spotted (stippled), bronzed, and dirty. A silken webbing may be on the lower surfaces of the leaves or on new growth. Infested leaves often turn brown, curl, and drop off. New leaves may be distorted. Plants are usually weak. To check for spider mites, hold a sheet of white paper underneath an affected leaf and tap the leaf sharply. Minute specks the size of pepper grains will drop to the paper and begin to crawl around.

Solution Advice

Apply an insecticide labeled for this pest, following label directions.
