Prosulfopyzone

Get the latest Prosulfopyzone news, regulatory developments and research covering this emerging herbicide active ingredient, including pesticide naming, registration, product development and future crop protection applications. Prosulfopyzone is a novel benzoylpyrazole herbicide developed by China-based Liaoning Cynda Chemical Co. Ltd.

The International Organization for Standardization (ISO) provisionally approved prosulfopyzone as its proposed common name on September 25, 2026. The compound is identified by CAS No. 3121509-99-4, while its full chemical name is 4-[2-chloro-4-(methylsulfonyl)-3-[(propylsulfonyl)methyl]benzoyl]-1,3-dimethyl-1H-pyrazol-5-yl N,N-diethylcarbamate. The provisional name remains subject to an objection period through March 25, 2027.

Coverage includes ISO naming and classification, regulatory submissions, pesticide registration, formulation development, manufacturer announcements and research on efficacy, crop safety and weed-control potential. As the molecule is at an early stage of international standardisation, information on approved crops, target weeds, application rates and commercial products will develop as regulatory dossiers and field research progress.
