I've found that Parsnip canker is worse in wet weather and in poorly drained soils.

Speed is important - prompt removal of affected plants greatly reduces spore production.

I always bury infected material rather than composting them as a way to reduce the risk of reinfection...in conjunction with a three year crop rotation, that is.
