Texas,
United States 
I have two (usually) beautiful evergreen hedge type bushes at my front door in Texas that are suffering from a blight of some type. I see no evidence of bugs or worms. Bushes are mature and about 2 meters tall. Leaves are spotting, turning brown, then dropping off. This has not happened before in the 12 years I have lived here.
On plant
Not sure. Perhaps some type of Laurel.

If they are Box [Buxus] then there is box blight that is a fungal infection with no treatment available.

It looks a bit like chlorosis if it was on my camellia or rhododendron, they need an acid soil, for that I would give a feed for ericaceous plants......I'm interested what other folk think....
