Quizalofop-P-ethyl (QPE) is a herbicidal chemical, the most common form of quizalofop. In practice the terms are sometimes interchanged, although there are also quizalofop-ethyl and quizalofop-P-tefuryl which are also variants of quizalofop. It is an aryloxyphenoxypropionate.
QPE is racemic, and it is the more active enantimer of quizalofop-ethyl.
Quizalofop-P-ethyl's HRAC classification is Group A (Australia and global), or Group 1 (numeric). Group A herbicides inhibit acetyl CoA carboxylase, (ACCase).
QPE is approved for use in Australia, all of the European Union, Morocco and China.
