ADI: 0.0005 mg/kg bw per day (1991)No Australian ARfD established
- If residues are present at the level of MRLs, estimated dietary intake of residues exceeds the JMPR ARfD (which is the same as the EFSA ARfD; Australia has no ARfD established). Phorate is not approved in the EU; there were data gaps to address concerns about dietary risks.
- There are no concerns with chronic dietary exposure when compared to the Australian ADI.
- Degradates of phorate are persistent and mobile in the environment, and are highly toxic to invertebrates and birds. Canada is phasing out phorate products owing to unacceptable risk to wild animals and birds.
- Phorate is highly important for pest management in tomato, eggplant, capsicum, shallots and spring onions. No alternative chemicals are available for some uses in vegetable crops.
- It is used to control wireworm and early season mites, aphids, leafhopper and thrips in cotton. No effective alternative pesticides are available. No insect resistance to phorate has been reported.
