Glad this has worked so well for you, Mark! Good to know that some of the "commercial" folks out there (importers, etc.) are employing sound quarantine practices more so than I recall in past years.
Interestingly enough, this Nix treatment has made its rounds pretty much worldwide now thanks to e-mail and the 'net. I have heard from people in Spain, S. Africa, all over Europe and Australia that have either followed this treatment and had great success, or had stories of smuggling this product from a neighbouring country as it was not available locally. I, of course, do not suggest anyone go as far as to engage in smuggling practices to acquire Nix where not available.
