Buxus bushes dying

[us4m4h]

I've had several buxus bushes since 10yrs. This year however, 2 have completely dried out. And others are also showing similar signs. I'm not sure if it's something fungul or not. Any ideas? Please see attached images.

It looks like the blight to me, box also gets attacked by box moth caterpillar, but I don't think it is that. There are two varieties, one turned up 35 to 40 years ago, the other more recently. I have some nice variegated box I got from my father and I keep hearing about it in the vicinity, but have avoided it so far.. This RHS page has lots of info, and more links at the bottom of the page.

Box blight is a fungal disease of box that causes bare patches, brown leaves and dieback, especially in topiary and parterres. It is particularly active during wet periods.
