Benzofenap Use and Manufacturing

Benzofenap is a 4-benzoylpyrazole molecule used for the selective control of annual and some perennial broadleaf weeds (especially Sagitaria spp.) in rice in Japan (as Yukawide) (31) and other countries such as Australia (as Taipan) (32). Mixtures with bromobutide, pretilachlor, pyributicarb, ormonilate are used to complete its spectrum.
