Langdon Research Extension Center plant pathologist Dr. Venkat Chapara says the canola diesase clubroot is becoming more prevalent in Cavalier County, North Dakota. “Infection levels are becoming severe in soils with pH levels ranging from 4.7-to-6.2,” says Chapara. “To manage clubroot, farmers should practice longer rotations, at least two-to-three years without canola in that field. Sanitation of equipment is also vital.” The disease can also impact components of cover crops mixes. “Clubroot is specific to the cruciferous plant family. In a cover crop mix, radish is the main component that can be impacted by the disease.”
