Admission

In 2001, Fenhexamid was added to the list of permitted pesticide active ingredients by the EU Commission , and in 2016 the permit was provisionally extended until the end of 2030.

Fenhexamid is approved under the trade name Teldor in Germany, Austria and Switzerland and is used specifically against gray mold ( Botrytis cinerea ) and Monilinia fructigena in many cultures.

In Switzerland, lettuce and other types of lettuce have a relatively high maximum residue level of 50 milligrams of fenhexamide per kilogram.
