ha-1), on weed dry-down, weed seed production and the viability and vigour of developing weed seeds. The field study examined the effects of different contact herbicides, tank mixed with two different rates of glyphosate (450 g a.i. This 3-year study at Saskatoon and Scott, Saskatchewan (2012-2014) evaluated the impact of several pre-harvest herbicides on juncea canola (Brassica juncea L.) and kochia (Kochia scoparia L.) dry-down, weed seed production, and the viability and vigour of the weed seeds. An effective weed seedbank management program is important to reduce the impact of problem weeds and is vital for farming operations to remain profitable and sustainable in future seasons. These resistant weed biotypes may not always impact the yield of the current lentil crop, but the resulting seedbank additions and subsequent spread of these resistant biotypes can have a long-lasting impact in successive growing seasons.
In western Canada, weeds resistant to acetolactate synthase (ALS) inhibitors have created an extensive challenge for many lentil (Lens culinaris L.) producers, particularly producers growing imidazolinone (IMI) resistant lentil.
