Dear Master Gardeners, Coordinators and Advisors:

The Statewide Master Gardener Office will be conducting an ON-LINE training about the FAQ System on next Monday, November 16th, at 11:00am. (For those of you that are unable to attend the Monday morning on-line training, we will be recording the training session and will share the URL with you after the training session has been completed).  To attend the on-line training just cut and paste this URL into your web browser:

The Statewide Master Gardener Program and ANR Communication Services are pleased to announce the launch of our new online system to assist Master Gardener volunteers find answers to hotline/help desk questions. The FAQ system (Frequently Asked Questions) enable volunteers to provide feedback to other FAQ’s and the ability to post their own questions with descriptions and photographs. UCCE Master Gardeners can access the FAQ system through the VMS, or through their UC portal. For further information and instruction on using the FAQ system, please click on the link below.  This first link is the FAQ Introductory video.  There are a total of six short videos that will guide you through the FAQ system, at the end of each video, there will be a prompt to continue on to the next video.

For more information or questions about the FAQ system, please contact James Sigala, Program Representative, UC Statewide Master Gardener Program, at jsigala@ucdavis.edu , (530) 865-1261.  This project was made possible by a grant from the Elvenia J. Slosson Endowment and UCANR Communication Services.  Project PIs include Pamela M. Geisel,  Scott Oneto, Dave Krause and Karl Krist.     Project Staff:  James Sigala

Two new serious pests have appeared in the western United States in the past months. Please familiarize yourselves with the biology and morphology of these pests so you can identify them.

The first is the European Grapevine Moth, which was found in the Napa Valley of California in October 2009.  This is the first occurrence of this moth in the United States. It is a serious pest of grape, feeding on the flowers and bunches. It is found in Southern Europe, North Africa, Anatolia, the Caucasus, and since 2008, in Chile.  The wingspan is 12-13 mm.  In September, The Napa County Ag Commissioner became aware of significant damage and crop loss occurring in Oakville and Rutherford area vineyards. Growers were finding numerous larvae in winegrape fruit clusters and experiencing significant crop damage or loss primarily from subsequent botrytis bunch rot. Growers had been asked to keep their eyes open for the presence of the Light Brown Apple Moth (LBAM), and many contacted their office and provided samples of damaged fruit, larvae, etc. Staff biologists also visited sites to conduct vineyard surveys and collect additional samples. These moth larvae and pupae samples were sent to the California Department of Food and Agriculture laboratory for analysis and were determined to not be LBAM or other common species, such as Orange Tortrix or Omnivorous Leafroller. CDFA entomologists utilizing newly acquired genetic lab techniques were subsequently able to identify the European Grapevine Moth, a very destructive pest of winegrapes which has never before been seen in the United States. 

he second pest is Cherry Vinegar Fly (CVF) , now called the

Spotted Wing  Wing Drosophila, (Drosophila suzukii ) was detected by the California Department of Food and Agriculture in fresh cherries near Gilroy CA in 2009. It now has been detected all along the west coast. The reports note that the larvae are found in ripe but undamaged fruit. The skin of the fruit has small holes resembling oviposition scars. According to the Oregon Department of Agriculture, fruits attacked include apple, blueberry, cane berries, cherry, peach, persimmon, plum, grape, and strawberry that it is also found in wine and table grapes. It is also found in Florida and As of October 13, 2009, the ODA reports it has also been found in wine and table grapes.
