Neither Daconil ZN nor Daconil Weather Stik can be used on blue spruce but is safe for use on pine trees. Either can be mixed with Floramite. Be sure to do a small tank mix test first to ensure that there is no clumping between the two products. We would recommend using Clearys Spectro instead for blue spruce. This is safe for use on blue spruce trees and will kill and prevent diseases on various ornamentals.
