ABSTRACT In response to changing market dynamics, the discovery of new herbicides has significantly declined over the past few decades and has only seen a modest upsurge in recent years. Nevertheless the few introductions have proven to be interesting and have brought useful innovation to the market. In addition, HT (herbicide tolerant) or HR (herbicide resistant) crop technologies have also allowed the use of existing non-selective herbicid
