Ding Dong the Wicked Witch—Chlorpyrifos (Used on 5% of Wine Grapes)—is Dead (But Only Sort Of): California Bans Sales (But Not Yet Use) Effective February 6

Five percent of California's wine grape
growers use Lorsban, a restricted material
linked for years to neurological diseases in
children and adults.

For decades, scientists—and especially pediatricians—have been calling for a ban on chlorpyrifos, an old school insecticide that is used by conventional and, sadly, yes, sustainable growers.

Starting Feb. 6, sales of the neurotoxin in California will be banned.

Glasses up! Break out the bubbly!

But maybe fill up the glasses only half or a quarter full, since this is not actually a full glass victory.

Over the years, I have written a number of articles about chlorpyrifos in the wine industry.

Sold as Lorsban, the insecticide has a dark history—invented by war chemists in Germany before World War II)—and has been in the cross hairs of public health authorities since the 1980's.

For the last year data is available—2017—California wine grape growers used 49,417 pounds on 26,430 acres.

Why should we care about this dastardly chemical? And will banning its sale in the state end its use?

• In a pesticide hair testing study conducted by the Greens in Europe, it was found in 10% of the 150+ participants.

• It's linked by numerous scientific studies to neurological conditions—including damaging child brain development—and neurological diseases like Alzehimer's and Parkinson's.

• It contaminates water supplies in California where it's used (now mostly in the Central Valley, but it's been used in Sonoma, Napa, Monterey and elsewhere over decades. It's becoming increasingly popular on wine grapes in the Tulare region). A story published by Environmental Health News about the study conducted by Beate Ritz (an expert who also testified in the Roundup trials, but that's another story) published in Environmental Health Perspectives summarized the study's findings:

People drinking well water within 500 meters of a dozen or more of the pesticides had a 66 percent greater rate of Parkinson’s, the study says. Airborne exposure only slightly increased the risk. [Boldings mine.]

• It also pollutes the air. 

• It is highly toxic to bees.

Heard enough?

• In 2015, the EPA said it wanted to ban the pesticide, but the wheels of government moved slowly. Cal EPA issued a press release in 2015 expressing its concerns over chlorpyrifos and worker safety. Its report stated,

"We are concerned about some workers who mix, load and apply chlorpyrifos to agricultural and other non-residential sites...We are also concerned about workers who work around areas that are treated with chlorpyrifos as part of their jobs." 

When Trump assumed power he killed the proposed nationwide ban.

Surprisingly

• Sustainable wine growers in the Wine Institute's Certified Sustainable Winegrowing program may use it but only during the first year of certification. (Why would this be allowed?) It is used to wipe out nematodes in replanting vineyards, controlling vine mealybugs and other uses. Basically, it's an exterminator.

• The California Association of Winegrape Growers, showing no compassion towards workers, residents or health officials (or the reputation of their industry) opposed the ban on selling it. According to an article published on Wine Business.com, the growers "and other agricultural organizations argued chlorpyrifos as another 'tool' in the farmers’ 'toolbox.'"

Sadly

• No one can legally buy chlorpyrifos in the state of California, but it is available outside of California. While California is now on the road to banning its use, that milestone, if approved, is two years away, according to state authorities. They are moving to cancel its use after a period of transition in which $5.7 million has been allocated to help growers using it try other products.

For now, its use was not made illegal—only its sale—so it remains a restricted material.

That means county ag commissioners must issue permits for its use. While ag commissioners are able to grant or deny permits, they cannot actually deny a permit for a legal chemical and it is still legal to use chlorpyrifos.

Just ask the Sonoma County ag commissioner's office: they had to give Sonoma Cutrer a permit to spray it on 100 acres in 2017. "We can't prohibit it because it is legal to use it, even though it's restricted," a spokesperson for the office said. Locals were alarmed. And rightly so. There is no requirement to warn when spraying is approved or about to take place.

UCLA researchers have documented the problem of ag commissioners' reluctance or inability to stop the use of restricted materials, writing a report on ag commissioners' track records. Read their full report here or local news coverage here. Certain counties will be more or less likely to continue granting permits.

A FEW CASE STUDIES FROM NORTHERN CALIFORNIA WINE COUNTRY

• SONOMA

Gallo used 147 gallons of chlorpyrifos on 400 acres at its Two Rock vineyard.

Gallo sprayed 147 gallons of it over Gina Gallo's favorite Chardonnay vineyard, Two Rock, in Petaluma in 2015.

Sonoma Cutrer sprayed it on 100 acres in Sonoma in 2017. (Source: Sonoma County Ag Commissioner's public data—pesticide use report records—available from the county ag commissioner's office upon request).

Parents with children in nearby schools and homes are not required to be notified when the spray is used.

• NAPA

Laird Family in Napa (and Sonoma) has consistently used chlorpyrifos for years.

It is the largest land owner in Napa with 5% of the county's vines.

So why are Laird Family's wines sold even at Whole Foods in Berkeley? (You'll have to ask Whole Foods' wine experts or post on Whole Foods social media.)

Take a look at the second post on chlorpyrifos here to see maps of where wineries used it from 2000 to 2017 (latest year data is available).
