Tree Fruit Scouting Course Learning Objectives
By the end of this course, you will know:
- The basic principles of Integrated Pest Management and how strategies and tactics are implemented in an orchard setting, primarily in apples.
- The major economically significant insect, disease, weed and wildlife pests of orchards (primarily apples), the biology of these pests and how to identify them.
- The methods used to monitor major orchard pests, critical times during the season when pests are active and require management and the appropriate thresholds used to implement a management tactic.
- How to use the pest forecasting models on the NEWA website to predict pest activity and thresholds for making management decisions.
This course will focus on orchard scouting and monitoring. It will only offer an introduction to management tactics (i.e. pesticide efficacy). We will review resources and how to use them to determine tactics that are most effective and make educated decisions on selecting effective management tools.
