Kristi from Whitefish, Mt writes

Will Bonide Liquid Copper Fungicide Concentrate work for yellow needle cast on blue spruce trees?

Answer:

Bonide Liquid Copper Fungicide is not labeled for yellow needle cast. We recommend that you contact your local cooperative extension office for product recommendations as many products will remove the coloring from the needles which many tree owners find offensive.
