Brazil bans trichlorfon

The Brazilian authorities have banned use of the organophosphate insecticide/acaricide, trichlorfon, with immediate effect. The national health surveillance agency, the Anvisa, issued a resolution ending use of the active ingredient at the end of last month. The agency recommended the withdrawal of trichlorfon last year following publication of its analysis on the insecticide as part of a reassessment programme covering 14 ais ( Agrow No 582, p 20).
