Interpretive Summary:

Technical Abstract: Stand establishment and persistence continue to be problems for Michigan growers. To determine the extent and severity of the problem, a survey of diseased seedlings from Michigan fields was initiated in 2008. Samples were collected of diseased seedlings for two years. In 2008, samples were collected from six MI grower fields and 1 research field, 3-5 beets per field. In 2009, 17 MI beet fields were sampled, 3-5 beets per field. Results showed that many pathogens are present in MI grower fields and that growers should be aware of the specific seedling disease causing organisms potentially affecting their stands. Pathogenic fungi isolated included Aphanomyces cochlioides, Alternaria spp., Fusarium spp., Phoma betae, Pythium spp., and Rhizoctonia solani.
