I was looking at systemic fungicides to treat dogwood anthracnose.
Would it be safe and effective to use a fungicide intended for lawns
instead of trees (spectricide immunox) that says it treats anthracnose,
on my dogwood?



According to the University of Maryland, "Fungicide should be applied
preventively at budbreak and every 10-14 days until leaves are fully
open. Repeat during cool, rainy spells and when foliage starts to turn
red in fall. Use fungicides containing chlorothalonil, mancozeb, or
benomyl."

Benomyl is a systemic. Chlorothalonil is the active ingredient in most
garden fungicides. I think bordeaux mixture should also work if you
don't mind the baby blue residue.
