| Curly top caused by Beet curly top virus is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. Host resistance is the primary defense against this problem, but resistance in commercial cultivars is only low to intermediate. In order to identify novel sources of curly top resistance, 14 sugar beet lines were screened in a disease nursery in 2013. The lines were arranged in a randomized complete block design with six replications. A curly top epiphytotic was created by releasing six viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 27 Jun. Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a continuous manner. Curly top symptom... |

| Eighteen commercial sugar beet cultivars were grown in a commercial sprinkler-irrigated sugar beet field near American Falls, ID where potatoes were grown in 2007. The plots were planted on 21 Apr 08 and managed according to standard cultural practices. Plants were free of foliar and root disease symptoms. Four roots representative of each cultivar were hand topped and harvested on 1 Oct. The roots were then placed in a cold room at 3°C and 90% relative humidity until they were assayed on 7 Jan 09. The roots were washed, dipped in 0.6% sodium hypochlorite solution for 1 min, rinsed in sterile reverse osmosis water, and then air dried in a laminar hood. A cross section of the root 8-10 mm thick and 45-70 mm in diameter was cut just below the... |

| Eighteen commercial sugar beet cultivars were evaluated in a commercial sprinkler-irrigated sugar beet field near Jerome, ID where winter wheat was grown in 2007. The field trial relied on natural infection for rhizomania development. The plots were planted on 22 Apr 08 to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 30 May. Plots were four rows (22-in. row spacing) and 34.5 ft long. The experimental design was a randomized complete block design with four replications per cultivar. The crop was managed according to standard cultural practices. The roots were mechanically topped and the center two rows were collected with a mechanical harvester on 9 Oct. At harvest the roots were evaluated for rhizomania (Rz rating) using a scale of... |

| Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems. To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 28 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2010 growing season in a randomized complete block design with 4 replications. At harvest on 18 October 2010, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building. Storage samples were evaluated for fungal growth known to correlate with sucrose loss. Depending on cultivar, surface root discoloration (rot and fungal growth) ranged from 1 to 14%. Overall, the... |

| Curly top in sugar beet is a serious problem that is caused by Beet curly top virus and other closely related species and transmitted by the beet leafhopper. In order to find a means of reducing curly top in sugar beet, 15 combinations of insecticide seed (Poncho, Poncho Beta, and Poncho Votivo) and foliar (Asana, Cyazypyr, Lorsban, Mustang, Scorpion, and Sivanto) treatments were evaluated versus an untreated check during the 2012 and 2013 growing seasons. An epiphytotic was created by releasing viruliferous beet leafhoppers 58 to 59 days after planting. The foliar sprays were applied 6 to 7 days before and again 6 to 8 days after leafhopper release. Seed treatments (active ingredient: clothianidin) were able to reduce symptoms by 26 to 42% and increase... |

| The sugar beet industry is continuously undertaking major efforts to reduce postharvest sucrose losses. In Idaho sugarbeet roots may be stored indoors or outdoors for up to five months. Sugarbeet variety genetic make-up, pre-harvest field conditions, harvest practices, and post-harvest storage conditions can affect storability significantly. Physical root conditions and root health before deliv- ery to the pile contribute to the magnitude of sucrose losses. Growers chose different varieties for a certain season and may plant more than one variety in a field. This practice renders it difficult to collect information on the exact location of varieties in the field and storage piles. Additionally, it’s a daunting task to physically tag... |

| Technical Abstract: Increased water demands and drought have resulted in a need to indentify crop hybrids that are drought tolerant, requiring less irrigation to sustain yields. This study was conducted to assess differences in drought tolerance among a group of genetically diverse sugarbeet hybrids. The study was conducted over three consecutive growing seasons (2008-2010) at the USDA Northwest Irrigation and Soils Research Laboratory in Kimberly, ID on a Portneuf silt loam soil (coarse-silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid). Drought tolerance was evaluated by measuring sucrose yield production of six experimental hybrids of KWS SAAT AG and one commercial hybrid (Betaseed Inc.) under six water input treatments. Hybrid drought... |

| Sucrose loss in sugarbeet storage is a concern for all roots, but particularly those stored under ambient conditions. In order to control or suppress insect issues in sugarbeet production and consequently improve root storability, two neonicotinoid seed treatments, Poncho Beta (60 g a.i. [active ingredient] clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seeds) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seeds), were used to produce roots from four commercial sugarbeet cultivars grown in Declo, ID. At harvest, eight-beet samples from each cultivar-treatment combination were collected and placed inside an outdoor pile. Samples were removed on approximately 30-day intervals beginning on December 6 and 8 in 2008 and 2009,... |

| Sugar beet germplasm, wild beta, and commercial check cultivars were evaluated in a commercial field (near Declo, ID ). This field was sprinkler-irrigated and winter wheat was grown in the previous year. 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 15 Apr 08 to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 12 Jun. 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 13 Jun 08. The crop was managed by the grower according to standard... |

| Rhizomania in the field and fungal root rot in storage can both lead to significant sucrose losses in sugar beet roots. In an effort to reduce these losses, sugarbeet germplasm developed by the USDA-ARS Kimberly sugarbeet program was evaluated for resistance to both these disease problems. Nine sugarbeet lines and four check cultivars were arranged in a randomized complete block design with six replications and grown in a field known to be infested with Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. The plants were evaluated for foliar symptoms in July, August, and September. Plots were harvested in October, roots were evaluated for rhizomania root symptoms, and roots from each plot were also placed in a commercial indoor storage... |
