Efficacy of in-furrow and post-emergence fungicides in controlling Rhizoctonia on sugar beet

Rhizoctonia damping-off and crown and root rot (RCRR) caused by Rhizoctonia solani AG 2-2 are increasing on sugarbeet in Minnesota and North Dakota. This soil-borne fungal pathogen can cause disease throughout the growing season and reduces stands and sucrose yield and quality. Several control options, when combined, help to reduce disease and include planting partially resistant varieties, cultural practices (e.g., early planting, rotation with cereal crops), and application of fungicides.
