Sulfur Dioxide Usage in Wineries:
Pesticidal use on empty wine barrels long overdue as separate function from wine additive.
Many California wineries are getting a crash course in governmental confusion this year because of a reclassification of sulfur dioxide as a "restricted use pesticide" when used to sanitize barrels or equipment. Suddenly, gas suppliers will not sell the SO2 to a winery unless someone has received the correct pesticide applicator's permit...and most county agriculture departments along with the State of California Department of Pesticide Regulation were caught off guard by the effects of this change in classification. Confusion was pretty high for some weeks, and made worse by the rumors, outrage, frustration, and the past experiences the wine industry has had with the regulation of SO2.
