New Herbicide and Fungicide Names Signal Breakthroughs in Crop Protection
Two new agrochemical names-Triflupyroxazin and Amfenamacril-have been provisionally approved by ISO, pointing to fresh innovation in herbicides and fungicides that could impact future crop protection strategies across the U.S.
The ISO Maintenance Agency has given provisional approval as of December 5, 2025, to Triflupyroxazin, an N-phenylimide herbicide developed by Liaoning Cynda Chemical Co., Ltd., and Amfenamacril, an aminocyanoacrylate fungicide created by the Jiangsu Pesticide Research Institute Co., Ltd. If no trademark objections are filed by June 5, 2026, both names will be officially included in the next edition of ISO 1750, the international standard for naming pesticide active ingredients.
Triflupyroxazin, also known by its development code CDH22117, carries the complex chemical structure 3-[7-fluoro-3,4-dihydro-3-oxo-4-(2-propyn-1-yl)-2H-1,4-benzoxazin-6-yl]-1-methyl-6-(trifluoromethyl)-2,4(1H,3H)-pyrimidinedione (CAS [134554-02-2]). Its Chinese common name is . The product shows potential as a new post-emergence herbicide targeting resistant weed species in major row crops like soybeans and corn.
Meanwhile, Amfenamacril-ethyl (2Z)-3-amino-2-cyano-3-[4-(ethylmethylamino)phenyl]-2-propenoate (CAS [3095661-21-2])-carries the Chinese name . It is designed as a fungicide for high-value crops facing increasing resistance to conventional treatments. Its unique mode of action and molecular structure could offer an important new tool in fungal disease management.
The introduction of these active ingredients reflects a growing trend of China-based agrochemical firms taking a leading role in global pesticide innovation. As U.S. farmers seek tools to combat herbicide- and fungicide-resistant pests while meeting sustainability and regulatory standards, molecules like these may offer new pathways to improved yields and more efficient pest control.
Both products would require further evaluation and registration through U.S. EPA and potentially state-level authorities before commercial use domestically. However, the provisional ISO naming represents a critical first step toward broader market access, research trials, and international distribution.
As the industry looks ahead to 2026, the potential adoption of Triflupyroxazin and Amfenamacril could bolster the U.S. crop protection toolbox-especially for producers navigating rising input costs, regulatory shifts, and increasing pressure for sustainable agriculture solutions.
