Biological Control for Mites and Using Permanent Groundcover Meeting

July 16 @ 8:30 am - 12:00 pm


With: Ann Kraemer, Shake Ridge vineyard manager and Central Sierra CE Farm Advisor Lynn Wunderlich

Who should attend?

Vineyard owners and managers, consultants and PCAs

Why is this workshop important?

Biological control uses natural enemies, either augmented (released) or conserved, to help manage pests. Shake Ridge has been releasing 6-spotted thrips to manage spider mites for several years-we will see the natural enemies and the release and talk about biological control in the vineyard, the pests targeted, and how to make sure your releases work. We will discuss and look for spider mites as well as Virginia Creeper leafhopper.

Permanent groundcover is perennial and includes cover under the vine. Shake Ridge has moved from an every-other row discing program to permanent cover. We’ll discuss how this can be beneficial for conserving soil, and some of the challenges when using permanent covers.

Presentation topics

  • Biological control-how to use it in your vineyard
  • Natural enemies and key pests targeted-2 spotted spider mites
  • Virginia Creeper leafhoppers-biology, ID, life cycle, native parasitoids
  • Permanent groundcover-benefits and challenges
