That look's like salt to me. See how it has traveled to the edge of the leaf. In Savannah salt intrusion into the fresh water is a possibility. It take's a lot to kill a boxwood, salt would do it.

This would be my guess to from the photos provided...also to the OP that gold plant that is now showing symptoms - that is gold mound duranta.

I've had Buxus sp. look that way up here. There have been a few reasons...weavils, broken branch, weed eater damage to the cambium, too much water...

Trim the dead branches off down low,and monitor it.

Is the hedge next to the driveway? A hot exhaust pipe can do damage that looks like that too.

I have 5 plants still in nursery containers. I put 12 in the ground in October. They all look the same with the red in the leaves and the white on them. They are slowly declining. I was thinking some kind of blight or powdery mildew, but I'm still learning pest ID. I had a Euonymous with the same white stuff on the foliage, and I blasted it with a water hose and its still there but the plant looks completely healthy otherwise. Thanks for the responses.

Down here in Texas the Euonymous family of shrubs (Manhatten, Boxleaf, Gold Spot, Little leaf, ect.) are all problematic and will get a variety of insect issues and even mildew. They should not be sold at all here. They should all be thrown in a compost pile along with all the Red Tips.
