Introduction

Apples have a large number of arthropod pests and diseases which need to be managed throughout the growing season to maintain healthy trees and marketable fruit. This scouting guide was designed as a pocket field book for easy use in the orchard or for quick reference. It provides information to help identify pests, beneficials, and pest damage with some guidelines for monitoring. Identification and scouting is a key component of integrated pest management (IPM) and will help you decide if, when, and how to take management action.
