Similar to White peach scale but WPS crawlers are two weeks earlier. Both species can occur on apple. See European red mite for oil rate and cautions. Recommended threshold is 3 to 6 encrusted areas per tree.
Insect: Winter Moth
See Green Tip. As winter moth larvae begin feeding on exposed tissue, Bacillus thuringiensis kurstaki (B.t.k.) products and Intrepid growth regulator that require ingestion for activity become effective options in addition to the materials listed at Green Tip.
