Managing Herbicidie-Resistant Kochia
Kochia (Bassia scoparia) is an annual broadleaf noxious weed that is an increasing concern for crop producers throughout Canada.
The troublesome weed can significantly impact crop yield. Research shows mean yield losses are greatest in grain corn, followed by sorghum, soybean, sugar beet, silage corn, sunflower, spring wheat, field pea, canola and oat. Near-complete crop failure (>90% yield loss) was observed in corn, sorghum, sugar beet and sunflower.
Proper management practices can help growers protect yield and preserve their crop protection options for the future.
