more are to be found: ca. 629 raw google web pages.

neither "aspersion" nor "dispersion" is particularly frequent, but
the latter has the semantic advantage of having the negative prefix
"dis-", so this is a candidate for eggcornhood.

i would have suggested it was a blend, if i could have thought of a
noun "dis-X" that would fit in the slot "cast dis-Xs on".  maybe
others are cleverer than i am.
