Evaluating seedbank stimulants for wild oat and volunteer cereal management on the Canadian Prairies

Wild oat is a widespread threat to annual crop production on the Canadian Prairies. Infestations are difficult manage due persistent seedbank, complex dormancy, long emergence window, herbicide resistance, and seed shatter corresponding harvest timings. The study objective was evaluate efficacy of potassium nitrate (KNO 3 ) pyroligneous acid for promoting germination wild volunteer wheat, barley, oat. A total 24 repeated experiments were conducted using freshly produced seeds ensure adequate endodormancy. Wheat barley demonstrated no endodormancy following formation rapidly emerged with moisture. All species imbibed but did not germinate in Petri dishes within solutions 5%–100%. Dormancy release observed 0.1% 1% solutions. KNO stimulate or any inhibitory at 125 kg N ha −1 . Pyroligneous increased 50% 100% applied 200 L first 10% second study. Emergence inhibition noted oat, wheat applications. This research further confirms that may activity matured seed.
