We have approximately 100 trees to treat. We would like to do the treatment ourselves.
The only product that we do carry that does not say it cannot be used on blue spruce for needlecast is Clearys Spectro. Please be aware that although the label states that it can be used on blue spruce, it may still bleach the trees, which is the problem with most products when they are used on blue spruce. You may also want to contact the cooperative extension office in your area to see what products they may recommend for you to use.
