@Killer723 and @Kakashisologod

Chapter 578, Itachi tries to use Sharigan genjutsu on Kabuto, yet it doesn't work, since Kabuto is avoiding eye contact. Itachi then switches to his MS, proceeds to look at Kabuto (Seems like he looks him in the eye) and still Kabuto is not placed under genjutsu. Only after Itachi's and Sasuke's initial scuffle with Kabuto's snakes, does Kabuto activate sage mode(seen by the darker markings on his eyes and horns).

So, if Itachi's non-visual jutsu is as powerful as @QuakingStar says it is, why didn't Itachi use it on Kabuto then?

P.S. Minato also has sage mode, so arguing that it didn't work on Kabuto because of sage mode is not a real argument. Kabuto was not in sage mode at that point as I have shown.
