COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:
Untitled document
1. Identify major vineyard pests, diseases and vectors during all stages of their life-cycles.
2. Develop a year-round management plan calendar that specifies when the pests, diseases and vectors are present, their critical monitoring periods and the best timing of appropriate control measures.
3. Identify and discuss control strategies for specific vineyard pest, disease and vector that include biological, cultural, mechanical/physical and chemical methods.
 

Objectives: Untitled document
In order to achieve these learning outcomes, during the course students will:
1. Distinguish among fungal, bacterial or viral vineyard diseases.
2. Categorize vineyard pests into insect, arthropod, nematode or vertebrate.
3.  Identify specific vineyard pests, vectors and diseases and explain their life-cycles.
4.  Identify specific beneficial insects, their role in potential control of which specific pest, and explanation of their life-cycles.
5.  Explain the role of beneficial soil microorganisms for potential control of specific soil pests.
6.  Identify symptoms and damage to grapevines and fruit associated to specific vineyard pests, vectors and diseases.
7.  Monitor and record pest infestation levels and disease severity levels in a vineyard.
8.  Explain an effective sampling strategy in the vineyard for monitoring pests and diseases in the vineyard.  
9.  Identify economic threshold levels of various vineyard pests and diseases.
10.  Define and discuss integrated pest and disease management strategies for grapevines.
11.  Define and discuss sustainable, organic and biodynamic methods of pest and disease management strategies for grapevines.
12. Identify and discuss control methods (biological, cultural, physical/mechanical, chemical) for specific vineyard pests, vectors and  diseases.
13. Develop yearly calendar showing when pests' activity, critical monitoring periods, and timing of the various control methods for each of the pests and diseases.
14. Define pesticide, including distinctions among the various subcategories, e.g., fungicide, herbicide, etc.
15. Compare and contrast classifications and modes of action for pesticides according to their target pest(s) or disease(s).
16. Discuss the laws and regulations and the governmental agencies that have jurisdiction over the approval and use of pesticides.
