COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

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 control strategies for each vineyard pest, disease and vector that include biological, cultural, mechanical/physical and chemical methods.

 

Objectives:
