Definition

ChEBI: Pyrazoxyfen is a member of the class of pyrazoles that is 1,3-dimethylpyrazole which is substituted at positions 4 and 5 by 2,4-dichlorobenzoyl and 2-oxo-2-phenylethoxy groups, respectively. A pro-herbicide (for the corresponding 5-hydroxypyrazole), it is used as a pre- or post-emergence herbicide for the control of annual and perennial weeds in rice. It has a role as a proherbicide, an agrochemical and a carotenoid biosynthesis inhibitor. It is a member of acetophenones, a member of pyrazoles and a dichlorobenzene.
