China approved epoxiconazole and clodinafop-propargyl

Date:06-12-2012

The Institute for the Control of Agrochemicals of Ministry of Agriculture (ICAMA) has approved registrations for fungicide epoxiconazole (95% technical) from JiangSu Sevencontinent Green Chemical and herbicide clodinafop-propargyl (95% technical) from Zhejiang Yifan Chemicals. These registrations are valid for five years.

Epoxiconazole, a broad-spectrum systemic triazole fungicide, was developed by BASF in 1985. It acts as an inhibitor of ergosterol biosynthesis, thereby interfering with fungal cell membrane synthesis. Epoxiconazole is widely used to target a large number of pathogens in various crops, like wheat, barley, rice, sugar beets, rape, beans, vegetables, grapes as well as apples. BASF got several Chinese registrations for epoxiconazole (92% technical, 75g/L EC and 125g/L SC) in 2007. The other registrants who registered epoxiconazole technical in China are Shengyang Sciencreat Chemicals and Lier Chemical.

Clodinafop-propargyl, developed by Ciba-Geigy, is a phenoxy herbicide. It acts as a systemic herbicide that acts on post-emergent weeds such as wild oats, rough meadow-grass, green foxtail, barnyard grass, Persian darnel and volunteer canary seed. Syngenta registered clodinafop-propargyl (95% technical and 15% WP) in China in 2009, and Traxos 5% EC (active ingredients: 2.5% pinoxaden + 2.5% clodinafop-propargyl) in 2010. The other registrants who registered clodinafop-propargyl technical in China are Zhejiang Yongnong Chem, Hangzhou Udragon Chemical and Lier Chemical.
