Yes that rumor (and the unwanted spammy emails) seems to making it's way around.

It's been floating around on at least 3 other forums; there's nothing to it.

I'll post here what I posted on another bonsai forum on lime sulphur.

I did a quick search and found this rumor has surfaced on a few other gardening sites, primarily rose enthusiasts. There is virrtually no documentation accompanying such posts that back the assertion.
 
The search indicated the University of Maine continues to recommend it for garden fungicide applications.
 
The EPA re-approved Lime Sulphur's use in 2005, saying it posed no real risk to fish, people or the food supply:
 http://www.epa.gov/oppsrrd1/REDs/ino...lfides_red.pdf
 
The University of Washington includes it in preventatives for stone fruit crops for 2011:
 http://cru.cahe.wsu.edu/cepublicatio...419/eb0419.pdf
 
This particular rumor has been around for several years--I've heard it on and off for the last four. Jim Lewis on the IBC recently did a search of USDA regulations and couldn't find any mention of a ban. I think it is a combination of things--the EPA is moving slowly on registering it and there is another kind of offputting "market" for it that might make law enforcement and regulators take notice.
 
From some of the things I can gather on the Internet, Lime sulphur is used as an ingredient in a chemical cocktail that people use to commit suicide. It is apparently often sold to for that use in private label bottles --unfortunately much in the same way it's sold in the bonsai market
 http://www.timesleader.com/TheDallas...7-31-2011.html
 
It's limited availability in bonsai circles MAY be due to its application in that sad "market." I've seen several "suicide pages" on the 'net where posters ask where they can get their hands on half gallons of the stuff.


Lastly, I searched the EPA's site and came up with this:
http://iaspub.epa.gov/apex/pesticides/f?p=CHEMICALSEARCH:31:7091457800141142::NO:1,3,31,7,12,25:P3_XCHEMICAL_ID:2686

It says Lime Sulphur is registered by the agency.

Thanks for the clarification. It seems, like many things, it can be abused.

It is still for sale and the info on it being banned is either rumor at best or profit oriented....

Apparently the news story link I posted was broken.
Hopefully this one works better:
