There is only one treatment for rot -  cut off all the rotted material - back to sound flesh.  If you have a reasonable bit of sound material, including the growing point - dust the cut surfaces with cinnamon powder, place in a pot of fresh, dry compost.  After a couple of weeks give a little water, keep your fingers crossed.  It may recover and grow good flesh - if you are lucky.
