Landscape Diagnostic Guide for Problems Affecting Woody Ornamentals and Herbaceous Perennials
Published 2011
This guide provides information on problems commonly associated with woody and herbaceous perennials of the upper Midwest. For each problem/pest there is a photo to aid in identification and detailed information on when and where the problem or pest is likely to be observed, signs and symptoms of activity, and treatment methods. Charts for each plant type help identify pests most likely to be causing damage at that time in the season on a specific area of the plant. For example, the chart for the daylilly entry indicates that damage to the flower between May 1 and May 10 would most likely be caused by thrips. Below the chart is information on the identification and treatment of thrips.
