Tips on identifying and controlling wild buckwheat, an annual broadleaf weed pest that is highly crop competitive and resistant to Group 2 herbicides.
With a fibrous root system that makes it drought-tolerant and highly competitive, a ropy, vine-like structure that easily chokes up combines during harvest and resistance to Group 2 chemicals, wild buckwheat can be a huge headache for growers in the Prairies. It’s tough to kill even during spring burn-off, but effective management is possible using multiple modes of action through tank mixes or combination products.
The stems are slightly angular, 12 – 35 inches long, trailing on the ground or twining on other plants and freely branching at the base. The leaves are heart-shaped, pointed,1/2 – 3 inches long, alternate and smooth. The flowers are greenish-white, small and appear in leaf axils or at the tips of branches.
- When scouting, check moist, low-lying areas for patches of wild buckwheat.
- A pre-seed burn-off is recommended with no-till systems.
- Scout fields early because this weed is most sensitive to herbicides.
- During its initial growth stages.
