NON-ORGANIC VINEYARDS: HERBICIDE AND FUNGICIDE USE
Most wineries in Napa still use glyphosate or glufosinate ammonium for weed control.
In 2018, more than 22,000 acres–about half of the vines–were sprayed with glyphosate (the listed active ingredient in Roundup), an herbicide that is still permitted under the county's Napa Green sustainable standard. Another 6,640 were sprayed with glufosinate ammonium.
The total number of acres in vine is roughly 44,000.
Here's where the glyphosate is used:

Fungicides, including neonicotinoids–which are highly toxic to bees, birds and butterflies (including Monarchs)–are more widely used.
Their use is permitted under Napa Green standards.
