Presentation slides from PSU Grape disease and insect pest management workshop

Here are my presentation slides from PSU grape disease and insect pest management workshop. Once again, I am looking for crown gall samples from neighboring states.  Please contact me when you have some (dying) vines to spare. I will come and get it. I am planning to visit PA vineyards this summer.

1) Late season rots (Botrytis, Sour rot, and ripe rot)

     - I learned some people want to have a file with a larger side size: here is a "1 slides/page" version.

2) Review of trunk/vascular diseases

     - Larger (1 slide/page) version
