Stimulating Germination in Wild Oats and Volunteer Cereals

The study objective is to characterize the dose response, interaction, and optimal mix of potassium nitrate and pyroligneous acid (liquid smoke) to determine the suitability of either pre-seeding or post-harvest germination stimulation of wild oat, volunteer barley, oats, and wheat. Wild oat is a strong competitor and can cause significant yield loss when emerging prior to cereals.  The development of herbicide resistance in wild oats results in additional herbicide inputs and costs, as well as standard practices to control wild oat.
