I think Harvey is right... it's the environment that is the problem. For what it's worth, we see alot of fungal/mold species (particularly in the ears) at our veterinary practice and a great way to kill them is with essential oil: any of the Eucalyptus species, especially E. citriodora is found to be most effective as an antifungal against human pathogenic fungi but will kill mold just as well. I have never applied essential oil to a saddle and dont know what the consequences will be... EO's are extremely powerful and maybe you could try a test spot underneath?? Any good health food/co-op/Whole Foods type of place will have a good Eucalyptus oil for you. I've had the best luck w/ a brand called "Wyndmere ". Mark S Denver, CO USA
