Florasulam + clopyralid for broad spectrum broadleaf weed control in winter cereals in southern Australia

摘要

In 2007 Dow AgroSciences registered florasulam + clopyralid as Torpedo herbicide (50 g florasulam + 300 g clopyralid L~(-1)) for broadleaf weed control in winter cereals. This combination of active ingredients provides good control of many key weeds including wild radish (Raphanus rap-hanistrum L.), Indian hedge mustard (Sisymbrium orientale L.), turnip weed (Rapistrum rugosum (L.) All.), spiny emex (Emex australis Steinh.), capeweed (Arctotheca calendula (L.) Levyns), bedstraw (Galium tricornutum Dandy) and volunteer legumes, with excellent cereal selectivity and flexibility for rotational crops. This paper summarises research trials to confirm cereal selectivity, weed control efficacy and crop rotation flexibility of this product.
