I don't usually recommend the 3 in 1 but if you have I'd say use it up. Bayer does make individual products, fertilizer, disease control and insecticide. It's better to just use the one you need when you need it and not use the combos.

Thank you Seil! I know I can trust your opinions. I hated to throw it out, because it had never even been opened.

What are the exact ingredients listed on the label?
