Diagnostic keys for each type of tree fruit direct you to the possible solutions based on the type of damage observed. Detailed descriptions, 500 color photos, drawings showing actual pest size, and management practices are given for 89 pests, 68 diseases, and 20 beneficials. For insects and mites, the time of year they may cause damage is indicated. Extensive glossary and index.
