I spray all my bearded iris including the historics and also my spurias
and Louisianas. Historics do not have any immunities. In my experience
they can get it just as bad as the newer hybrids.
As a matter of fact I was spraying today. It took me 4 1/2 hours. I
use a 3 gallon Solo backpack sprayer and sprayed 30 gallons.
