No more fresh wasabi at KCC Farmers' Market

I was just about to post that I found stainless-steel wasabi graters at Longs Drugs Pali, of all places, when the bad news came in--due to some kind of black fungus problem, there won't be any more fresh wasabi at the KCC Saturday Farmers' Market.
It's enough to make you cry. What a letdown. All those plans on how to use wasabi in both washoku (Japanese cooking) and yoshoku (Western cooking) now given up.
