Ferti-lome Liquid Systemic Fungicide II is not labeled for Rhizosphaera. The best 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.
