I pulled mine and reused the pot to pot up a tomato plant.
I think you have to be careful reusing a pot which may have had an infection. I've started giving pots and things a rinse in a bleach solution to be on the safe side before reusing them.
Anyone noticed that the hardware megastore has cheap 9 litre plastic buckets for about 80 cents, but a pot plant pot of the same size is much more? I think I'll be buying a bunch of buckets and using the drill to make some drainage holes for next season.
edit: Chillies and Tomatoes are in the same family so they can get the same diseases.
