I have some sort of scale (see pic's) on my Taxodium distichum 'Cascade Falls' and am wondering how to treat it. They are black and redish orange. They have a powdery substance when you pick them off. I have Ortho (Isotox) but I think it is only effective in the crawler stage - this usually around June correct? Or is it safe to use a product like Bonide All Seasons Oil - it says that it can be used year round but just want others opinions. Anyone know what kind of scale it is by chance?
