Dwarf Swiss Stone Pine

Any idea what is going on with my Swiss Stone Pines? Pic is of the worst one. The other two have the white stuff mainly on new growth.

Thank you for the photo. It clearly looks like something is going on. Could you tell me if the rest of the tree looks healthy? Any needle changes, color or drop? Has anything occurred in the last year around the trees? Thank you for any additional details you can provide.
