I know the active ingredient is useful for needlecast in Norway spruce, but read that the weather stick component could hurt the trees. I’m compelled by it staying on longer, but also don’t want to hurt the trees further.
Daconil Weather Stik Flowable Fungicide is labeled for needlecast on Spruce trees (conifers). It should not harm the tree but may cause some discoloration that will return to normal after a few days
