I have no experience with this plant, but using a surfactant that can penetrate thick or waxy leaves might help.  I've had luck with Clean Cut surfactant.

>>> I don't agree that Italian Arum is easily controlled or that it "disappears." Yes, the leaves are primarily only out in the cool season and then wither away in the warm season, which is when the flowering spike appears, But the plants produce abundant bulbs or corms that remain underground. I believe, although I can't prove, that critters spread the bulbs as well as the seeds. So removing the flowering spikes may be helpful but it will not eliminate the plants or prevent their spread. I see this plant becoming increasingly abundant in Arlington Virginia's natural areas and even in my own back yard. I think it is a significant invasive of concern at least in the DC area of the Mid-Atlantic and it is not yet clear how best to control it.

I was growing it experimentally in a wet, woodland area to see if I could hybridize with Arrow - the native - it didn't take. It dies back in the summer and one can simply control it by gathering all of its red fruit * (berries are poisonous to humans, use gloves).* It is easily controlled by collecting and removing all of  the fruit. Also, it 'disappears'  completely - both original species and the hybrid after it grows fruit in the summer. It makes a very short lived appearance. Instead of control with herbicide one can replace it with the native Peltandra virginica - Arrow Arum - it will grow in the same conditions after one removes the fruit-berries of  the non-native or Symplocarpus foctidus (skunk cabbage).
