Hello,

I noticed this white stuff on the needles a couple weeks ago and I'm thinking it's a scale of some sort. Here's a pic. This plant is at the curb and takes a lot of salt from the plow. I scraped off some of this substance to see if it was salt but it is not and underneath the white stuff is black gooey stuff. I'm thinking it's a sucking type insect of sorts, so as a precaution, I have already treated with a systemic insecticide good for scales. What do you all think?
