In Japan
- An antifungal agent used to prevent mold on potatoes (ばれいしょ) after harvest.
- Because it is an antifungal agent, the purpose name is written alongside, as in “防かび剤（ジフェノコナゾール）” (antifungal agent (difenoconazole)). Its short name is “トリアゾール” (triazole) (the same as for propiconazole).
- It is listed among the additives for which antifungal agent labeling is required even when the food is sold loose without packaging.
Japan's standards for use
- Potatoes (ばれいしょ): maximum residue level 0.004 g/kg
- May not be used in any other food
This is a summary of the standards for use. See the source list for the exact conditions.
In the EU
- It is not on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II), so it cannot be used as a food additive in the EU.
- In the EU it is treated as an active substance of pesticides, not as a food additive, and residues in food are controlled by the pesticide residue limits (Regulation (EC) No 396/2005).
When it is labeled under a shared name
Difenoconazole may be declared on the label in the same way as “防かび剤（OPP・TBZ・イマザリルなど）”. See Post-harvest fungicides (OPP, TBZ, imazalil etc.) for details.
