[align=left]Hi. My in-laws have tasked me with figuring out what is killing their shrub.* They couldn't tell me what kind of shrub it is so I've linked pictures of the shrub and the disease.[/align]
[align=left]The shrub is deciduous, woody, and non-flowering.* It has shiny, green leaves which turn yellowish in the summer.* It is a taller shrub, 5-6ft.* [/align]
[align=left][/align]
[align=left]The disease seems to be some sort of mold or fungus as far as I can tell, though my internet research has afforded me nothing with which to match it.* There are white, uniform, "barnacles" (for lack of better descriptor) that pock the leaves and bark.* Some of the white things turn dark.* Eventually, leaves become covered with them and die off.* The far-shot picture shows you a section in the bottom right where a large portion of the shrub has already died off.[/align]
[align=left][/align]
[align=left]There is the same kind of shrub about 6ft away that is healthy, though I can see some of the white things starting to appear on that shrub as well.[/align]
[align=left]My mother-in-law also said another shrub died from the same thing (I think that was a rhododendron, though I'm not sure of that either).[/align]
[align=left]Any assistance you can provide with shrub and disease identification and eradication would be greatly appreciated.* We are located in North Carolina, if that helps at all.* Thanks.* DJ[/align]

Hi DJ,
Your mother in law's shrub looks to me to be a variegated Euonymus, probably Euonymus japonicus.* You mention it's decideous but this is evergreen.

It is infested with Euonymus scale.* I would suggest removal and replacement with something that is resistant to the scale since you mention that another has died from this.* You appear to have quite an infestation.* You could try pruning, topdressing the soil with an inch of compost and then 2" of shredded mulch to boost the immume system.* Try using Neem oil as directed several times a year for control.* Here's some helpful info on Euonymus scale.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.

Wow.* Quite an infestation indeed.* Thanks for the info and prompt reply.* They'll most likely get rid of that shrub and take measures to keep the other ones.* Thanks.* DJ
