November 14, 2018: Summary of the Fall SCMWA Grower Meeting

The 2018 Fall Meeting provided a venue for our local winegrower community to compare notes on the recent 2018 harvest and subsequent winemaking decisions. Featured speaker was Dr. Peter Salmone founder of the newly formed Applied Research Innovation Collective. Dr. Salmone presented the mission of the Collective as a collaborative research based platform to investigate relevant viticulture and enological inquiry without industry bias. He brought new information on how and when smoke taint influences wine and on specific fruit processing options post harvest and their effect on wine style and longevity. Participants were encouraged to bring wine from the 2012 vintage as this was deemed most similar to the current 2018 year.

SCMWA offers a big thank you to Jim Cargill and House Family Vineyards for hosting.

August 15, 2018: Summary of the Summer SCMWA Grower Meeting

The Summer Meeting brought focus to the insidious threat of mealybug infestation in our vineyards and the long term consequences to our vines and our wines. Dr. Sheena Sidhu an entomologist discussed the life cycle of this pest and the most effective control methods both chemical and biological. Sam Earnshaw of Hedgerows Unlimited presented timely information on creating successful beneficial insect habitat around the vineyard to enhance natural control of potential pests. Check in with hedgerowsunlimited.com for more information. David Goldfarb, Winegrower at Clos de la Tech, gave a tremendous presentation on his experience with combating vine mealybug using a variety of practices including insecticides, pheromones, cover crops and releasing predator insects. Attendees were encouraged to bring a wine they felt most reflected their terroir and/or winemaking style.

SCMWA wishes to express a special thank you Larry Schaadt, Regale Winery for generously hosting this meeting and to VASCM provided refreshments.

May 3, 2018: Summary of the Spring SCMWA Grower Meeting

The Spring Meeting titled “En Primeur” featured the fresh wines of the 2017 vintage (remembered affectionately as “fire and ice” ) Featured speaker was John Raytek of Ceritas Wines. SCMWA wine producers were asked to bring samples of the 2017 vintage and to discuss their enological decisions related to the challenging harvest season. John summarized his philosophy as: “Through observation, vintage after vintage, we are continually reminded of the simple principal that most of the important work occurs in the vineyard, and the role of the winemaker is to allow the vineyard to express itself in a balanced, inimitable wine.”

February 20, 2018: Summary of the Winter SCMWA Grower Meeting

The Winter Meeting coordinated with the University of Davis Viticulture and Enology department to promote their “On The Road” Series. The UC has launched this new program to take research into the field as not everyone can get to Davis for their wonderful regular seminars. The late Dr. Doug Goublar made one of his last public presentations and shared his vast knowledge on trunk disease and mildews. He included practical biological, physical and chemical treatment options. Dr. Dario Cantu followed with his current diagnostic and next generation research on trunk disease. He included information on prevention and early treatment options. Larry Bettiga, UCCE Viticulture Advisor to our region presented important data and biological information on mealybugs in our area. Dr. Anita Oberholster from UC Davis updated her latest findings on Red Blotch. The SCMWA Winegrowers hosted a side panel from SJB Ag-Nutri Australian agronomist Mark Bingham post meeting for growers interested in following up on the 2017 meeting.

Spring 2018 Pesticide Safety Instructor Training workshops

HI everyone:

There are new regulations related to your vineyard employees.

Opportunities for training are listed below as well as a PDF summary of the changes.


Prudy Foxx

Registration is now open for Spring 2018 Pesticide Safety Instructor Training workshops

UC IPM is partnering with AgSafe to offer up-to-date instructor training programs that are approved and co-funded by the California Department of Pesticide Regulation (DPR). Updates to the Federal Worker Protection Standard (WPS) that will have the most impact on CA agriculture include:

  • Annual pesticide safety training for all fieldworkers
  • Instructors must attend an updated and approved Train-the-Trainer course, and
  • Expanded training content for fieldworkers and handlers

Participants who complete this training will become qualified to provide pesticide safety training to fieldworkers and pesticide handlers, as required by California state regulations and the revised Federal Worker Protection Standard (WPS). Visit the workshop website for specific date/location information and to register. Spring 2018 Pesticide Safety Instructor Workshops


Innovative Technique Uses Kites to Repel Unwanted Birds from Vineyards

Reposted from Wine Industry Advisor Network. Shared by Prudy Foxx.

The practice of controlling nuisance birds in vineyards or other open spaces where they can wreak havoc to business is nothing new. In fact, companies have been attempting to address the problem for decades with repellants like gas cannons, reflective tape, crop netting and other means.

But just last year, an innovative concept emerged from a company called Falcon Crop Protection. Designers came up with the idea to use bird’s natural fear of predators to steer them away from valuable vineyards with a kite that mimics the appearance and movements of a peregrine falcon.

Known as FrightKites, the devices are made with a durable material designed in the shape of a predator bird that self-launches and flies at the end of a pole on an extension line that can lift the kite up to 65 feet high.

The kite has the outline, coloring, wings, tail and eyes that look frighteningly life-like to a small bird. Its profile arches in strong winds, which make it appear to be hunting, and its wingtips flutter at the end like a real falcon. Best of all, the innovative FrightKite design allows the device to hover, climb, glide and dive just as a predator does when it’s on the attack.

According to Roger, the President of Falcon Crop Protection, FrightKite efficacy has been nothing short of amazing right from the start.

“We were in Napa (testing the kites) at 65 feet and we saw a flock of finches,” Roger recalls. “They took a hard right turn and disappeared. We said to each other, ‘Did you see that?’ We had no idea it would be so good.”

It’s so good, in fact, test site vineyards from Paso Robles through Healdsburg have reported a 95 to 100 percent repulsion rate of birds – and most are ordering multiple kites to continue to protect their crop investments. Each FrightKite can safeguard up to 1.5 acres. Two kites will more than double the effect.

“The great thing about FrightKites is that there are no ill effects on the environment, no harm done to the birds,” Roger points out. “It’s vastly more cost-effective and less labor intensive than our nearest competitor’s netting option.”

Roger emphasizes that FrightKites can be used throughout numerous harvests as they are only flown four to five months out of the year. He notes that the versatility of the kites is such that they can be moved from site to site within vineyards to accommodate the different rates of veraison for multiple varietals.

Roger also reports that the applicability of FrightKites goes beyond vineyard protection. A customer on Angel Island contacted him recently about a persistent problem with aggressive seagulls at an airport hangar. Roger offered him a FrightKite for a two-week test trial.

“Before I got back to my office, he rang me,” Roger laughs. “Apparently, as soon as it went vertical, the gulls went squawking and disappeared.”
