No Australian ARfD established

Key issues

  • Very long REIs are required which may make it unsuitable for home garden uses.
  • Preliminary estimate with respect to use on vegetables indicates that chronic dietary intake of residues exceeds the ADI.
  • No Australian ARfD has been established. Estimates using overseas ARfDs raises concerns about acute dietary exposure for a number of commodities.

Stakeholder perspective

  • Not a cost-effective chemical for controlling mites in cotton. Further, a variety of alternatives are available
  • Not an effective miticide in turf
  • This is a highly important chemical for pest management across a number of vegetable crops; alternatives are available for some uses, but not all.
