Sedition is a noun. Unlike some nouns that have been turned into verbs, for example "to medal", I don't see how you can apply it to sedition. You might encourage, incite, welcome or commit sedition. I'm sure there are other possibilities.

Samad: I think "GuideDogSaint" is correct, about there being some nouns that do not transition well into common verb usage. I cannot "sedition" anything. From the same Root I can think of the word "seduce" but that is almost always used with a sexual connotation, but sometimes to indicate a persuasion or trickery; but never in the same context as a "sedition". If you want another word that will work, SUBVERT may work rather well to show a kind of "sedition" or "seditionary" activity. Subvert pertains to SUBERSION, meaning undermining or eroding some structure, whether physical or governmental. Thus, we can say we engage in Sedition by way of subversive activities or subversion of some social structure. Sedition is one of those words that custom has not assisted in the transition to verb usage. Corruption might work. I can corrupt something. .
