Sugar beet germplasm and commercial check cultivars were evaluated in a commercial sprinkler-irrigated sugar beet
field near Rupert, ID where winter wheat was grown in 2006. The field trial relied on natural inoculum for rhizomania
development. The seed was treated with clothianidin (2.1 oz a.i. per 100,000 seed) to limit the influence of pests and curly
top. The plots were planted on 3 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 23 May. Plots were
single rows (22-in. row spacing) and 10 ft long. The experimental design was a randomized complete block design with
eight replications per entry. The field was cultivated on 24 May and 15 Jun. The crop was managed by the grower
according to standard cultural practices. The roots were mechanically topped and lifted on 27 Sep. The first ten roots in
each plot were evaluated using a scale of 0-9 (0 = healthy and 9 = dead). The first eight roots were placed in a mesh onion
bag and held in an indoor commercial sugar beet storage facility set to hold 35°F. On 1 Feb 2008, the roots were evaluated
for the percentage of surface area covered by fungal growth (an undescribed Basidiomycete that correlates with sugar loss in
storage). Data were analyzed using the general linear models procedure (Proc GLM-SAS), and Fisher’s protected least
significant difference was used for mean comparisons
