Pesticides

The most comprehensive database for fluorinated pesticides, including the inorganic compounds Cryolite and Sulfuryl Fluoride, as well as hundreds of organo-fluorine compounds that may well prove to be as toxic, or more toxic, than the chlorinated pesticides they are replacing.

PHASE-OUT OF USE: The US EPA in January 2011 announced that it agreed with “all” of the objections for the use of sulfuryl fluoride submitted by FAN, EWG and Beyond Pesticides. At the same time they announced a phase-out of the use of sulfuryl fluoride. The pesticide industry reacted with comments that it would suffer financial hardship if the phase-out were to happen. The last date for public comments on the issue was July 30, 2012.
