Documented Uses

• Used as oxyphenoxy acid ester herbicide for spring wheat; [Reference #1]
• Herbicide registered for use on spring wheat.
• Used for post-emergence control of annual grasses, including Avena, lolium, Setaria, Phalaris and Alopecurus spp. and in cereals ...
• Clodinafop-propargyl can be made by reaction of 2-fluoro-4-chloropyridine with propynyl 2-(4-chlorophenoxy)propionate
• /In animals,/ hydrolyzed to the corresponding acid, which is excreted in urine and feces. ... In plants, rapidly degraded to the acid derivative as major metabolite.
• Clodinafop-propargyl is extensively metabolized (<0.3% remaining as clodinafop-propargyl). The major metabolites evident in the excreta were clodinafop (CGA 193469) and its taurine conjugate. The metabolites in fat were diacylglycerides and triacylglycerides of clodinafop.
