Tourney Turf Fungicide is not labeled for black spot from roses. We would recommend using Bonide Liquid Copper Fungicide instead. It is labeled for black spot and many other rose diseases.
Tourney Turf Fungicide is not labeled for treating spruce trees for needle cast. The only product that we do carry that does not say it cannot be used on blue spruce for needlecast is the Clearys Spectro. Please be aware that just because the label permits this use, the product can still bleach the trees which is the problem with most products when using on blue spruce.
