Lime Sulfur rumors
« on: December 31, 2011, 09:34 AM »
There is a rumor going around that "Lime Sulfur has been banned by the EPA". This appears to be false, Lime sulfur was required to be reregistered (2005) as part of a program to ensure that products released before registration requirements actually met safety and toxicity standards. Lime sulfur (Calcium polysulfide) passed this review and was approved for reregistration, sale and use . One company (Bonide?) and perhaps others have chosen to not pay for registration and have thus stopped manufacturing the product. Several states have banned Lime Sulfur sales/use- CA, ME, RI, and a few others, in other cases the product is not registered for use. Here is the latest EPA doc that I have found on the topics: http://www.epa.gov/oppsrrd1/REDs/inorganic_polysulfides_red.pdf.

So has anyone seen anything from EPA more current than this? Or are idle rumors running rampant over the internet?

...but, I got an unsolicited spammy email trying to sell me some, explaining that it had been banned, so it must be true.

Things freeze solid these days deep in the near boreal forests of Maine.

Do we need to start looking for an alternative? Larry

Another unwanted email today trying to sell me something, screaming about the sky falling and lime sulfur having been banned!

Funny, the whole first page of Google results for "lime sulfur banned" shows bonsai forums are the only places this is being discussed.  I'm sure the day may come when it does happen, but I doubt it will be the end of the world.  I think I'll refer to Kirby's EPA article instead of relying on unsolicited emails.

Had some Europeans at the Taikan-Ten in Kyoto last November trying to track down some bottles as it was banned there.  Not sure where theywere from.  I really really hate when effective chemicals with a proven track record are banned (Alar, Methyl Bromide, etc.).  Giving a mouse it's weight in just about anything will kill it......   
If this chemical ever gets banned we're in trouble as it is a very old one.
