Greetings, welcome to the Forums.

So it's in the U.K. too! Some of my Yucca get this, and I've even seen the culprit, ...once! It's the larvae of a very small moth.

Read about the full saga here: http://www.agaveville.org/viewtopic.php?t=400
If I am correct, Post # 18 reveals the answer.

So what is the solution? I recommend Bacillus thurningiensis (B.t). Pry apart as many of those crystallized leaves as you can and try to get the B.t. solution deep into the leaf crevices. Good luck.
