BASF extends Armezon to western Canada
BASF has extended the use of its post-emergence maize herbicide, Armezon (topramezone 336 g/litre), to western Canada. The product controls "tough" weeds such as wild mustard (Sinapsis arvensis), barnyard grass (Echinochloa crus-galli) and green foxtail (Setaria viridis), with volunteer canola recently being added to the label, BASF points out. The company has been selling Armezon in eastern Canada since 2012. Topramezone was introduced in 2007 as Impact by Amvac Chemical under a 2005 North American licensing agreement.
