Common name: Cyhalofop-butyl（CAS NO: 122008-85-9）

IUPAC name: butyl (R)-2-[4-(4-cyano-2-fluorophenoxy)phenoxy]propionate

Chemical Abstracts name: butyl (2R)-2-[4-(4-cyano-2-fluorophenoxy)phenoxy]propanoated

CAS No: 122008-85-9

Mode of action: 
Selective systemic herbicide. Activity comes from the formulation of the herbicidally active monocarboxylic in the initial metabolic step in the susceptible grasses after leaves absorption.

Application:  
Control of annual and perennial grass weeds in rice field with only post-emergence activity. It is highly effective against barnyard grass, Leptochloa and some other paddy weeds. In some situation, Cyhalofop-butyl can be used to deal with propanil or quinclorac-resistant Echinochloa. It is suggested that 2.3 L/ha of crop oil concentrate be added to the tank with the herbicide. To maximize the efficacy, better be applied within 2 weeks following flood establishment in rice fields.

It is mainly used in rice field, live field, transplanting field, most of the malignant grass weeds such as valerian, Qianjin, and tendon, and can effectively control the weeding of quinclorac, sulfonylurea and amide. The agent produces resistant weeds.
