Biology and control of foxtail barley
AWC contribution: $30,000
Foxtail barley is a difficult to control weed that can be managed within a competitive crop rotation, but location in saline areas tends to decrease crop competition, making growers more dependent on chemical control. This research project proposes to combine glyphosate and pyroxasulfone to provide an integrated approach for controlling both established and seedling foxtail barley.
- Find optimal combination of herbicides for control of established and seeding foxtail barley in spring wheat
- Quantify the time of emergence of foxtail barley seedlings based on growing degree dates or thermal time
- Use the project to train a graduate student in weed biology and herbicide activity
Benefit to producers:
It has been reported that foxtail barley decreases wheat yield. Foxtail barley is also one of the hardest to control weeds in spring cereals and is increasing in south and central Alberta. Research finding will address grower’s needs for a herbicide solution for foxtail barley.
