In Japan's national residue testing (fiscal 2024)
| Produce | Detected / tested | Detection rate | Over the limit |
|---|---|---|---|
| Domestic | 8 / 4,908 | 0.2% | 0 |
| Imported | 0 / 2,472 | 0.0% | 0 |
Found in domestic foods: cucumber (including gherkin), eggplant, apple (max. 0.04 ppm)
Tests are counted as pesticide × sample. Any detection counts as “detected” — it does not mean the limit was exceeded. For pesticides outside the top 20, figures are summed from the food-by-food tables of the full report.
Evaluations abroad
- WHO acute toxicity class
- II (Moderately hazardous), LD50 595 mg/kgBased on the toxicity of the undiluted active ingredient given once, mainly to rats by mouth (LD50 = the dose that kills half; the smaller, the stronger the acute toxicity). It is not an assessment of the safety of residues in food.
- EU
- Approved in the EU (approval expires January 2027)Designated a “candidate for substitution” (to be replaced if safer alternatives exist).EU ADI: 0.01 mg/kg bw/day; ARfD: 0.02 mg/kg bw
