Any eggs found require a dormant treatment, as aphid colonies may quickly spread over the tree. Treat nonbearing trees to prevent stunting of terminal shoots. Because overwintering eggs are located on the bark, delayed dormant application will greatly reduce populations. Codling moth sprays should be chosen with aphid control in mind. Follow restrictions on supplemental label. . . .
