VASCM: Weed Slayer Quarantined for Organic Violation - regulatory action in CA

[Ken Swegles]

Good morning David,

I am in the process of organizing a Viticulture meeting about this very
subject and hoping to have it dialed in by the end of next week.  We are
looking into some new products on the market that may be a good substitute
but are not OMRI listed yet.  I will keep you informed about the meeting
and happy to discuss some of our current options over the phone in the
meantime.

Cheers,

Ken
