I am told to use Docket DF, I have a 26 gallon sprayer.
Docket DF is not labeled to be used on blue spruces and actually states on the label do not use. 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 it the product can still bleach the trees which is the problem with most products when using on blue spruce.
