Removing Mold On House Paint ?

Hello: Have a Colonial outside of Boston that was painted about 8 yrs ago with while Latex paint.
One side of the house has a few relatively large spots of light green that has developed; probably a mold of some sort.
Too old now for the ladder bit.
Is there some type of spray that I can hook up to the hose and spray the stuff with. Hopefully something that will not harm or discolor the basic paint ?
Brand / Mixture Amount, etc. ?
Also, that will not require wiping, of course.
Any suggestions, please ?
Thanks, Bob
