Remembering Lake County Winegrower John Roumiguiere

Donna and John RoumiguiereFormer Lake County winegrape grower and long-time supporter of Lake County’s winegrape industry, John Roumiguiere passed away in mid-December.

John was one of the founding Board Members of the Lake County Winegrape Commission, serving from 1991 to 1999 and again from 2009 to 2010.

The Roumiguiere family – father Bob and sons John and Rob – was instrumental in shaping the burgeoning winegrape industry in Lake County in the early 1990s. John was a pioneering viticulturist who played a key role in the Commission’s work, with a focus on sharing his viticultural experience. He initiated the Commission’s Research and Education Committee, hosted educational meetings at his vineyard, and worked closely with University of California researchers and advisors, often donating test plots for various grapevine trials.

Our hearts go out to the Roumiguiere family.

A celebration of life for John Roumiguiere will take place Saturday, January 4, 2020 from 12pm to 4pm at the Little Theater in the Lake County Fairgrounds.

In lieu of flowers the family has asked that donations be made in John’s name to St. Jude Children’s Research Hospital or the Disabled Veterans National Foundation.

CAWG’s Statewide Update: Potential New Pest Management Tool?

By Michael Miiller, Director of Government Affairs for the California Association of Winegrape Growers (CAWG)

On December 6, 2019, the California Department of Pesticide Regulation (DPR) issued a Notice of Proposed Final Decisions and Public Reports that included a proposed registration of Sequoia CA and Transform CA. These products contain the active ingredient Isoclast Active (sulfoxaflor).

Information regarding the proposed decisions, including the public reports and proposed product labels are available on DPR’s website.

Corteva Agriscience states Sequoia “is an insect control product for many fruit and vegetable crops. It provides fast-acting and consistent control of sap-feeding pests, including aphids, whiteflies, mealybugs, leafhoppers, plant bugs and psyllids… Dozens of field trials done in commercial fields and in greenhouses have shown that Sequoia has minimal impact on key beneficial insects, including assassin bugs, lacewings, ladybugs and minute pirate bugs. Additionally, Sequoia has no negative impact on beneficial mite species.”

The proposed registration is open for public comment until January 4, 2020. If approved, California would be the third state in the country to make this product available.
