Insecticides differed consider ably in placement effects on performance, although yield dif ferences were rare. Effects ofpostapplication rainfall on effi cacy were insecticide- and placement-specific. Placement method had the greatest impact on performance of terbufos and chlorpyrifos, the least water-soluble insecticides tested. Spoon-applied terbufos reduced root maggot feeding injury more than conventional banded and modified in-furrow applications in two of five environments. Plots treated with spoon-applied chlorpyrifos yielded 30.8% more recoverable sucrose than those that received the insecticide as a banded application in 1999, the year of least postapplication rainfall. Aldicarb, the most water-soluble insecticide tested, was gen erally unaffected by placement. However, spoon-treated aIdicarb plots produced 19.2% less recoverable sucrose than those receiving the material via modified in-furrow place ment in 2001, the year of highest postapplication rainfall. Contrasts of root injury across ail insecticides suggested that, of ail placement methods tested, the spoon technique has the greatest potential to optimize granular soil insecticide effica cy for management of sugar beet root maggot larvae.","PeriodicalId":403165,"journal":{"name":"Journal of Sugarbeet Research","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130636779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

About half of the U.S. sugarbeet crop is produced and processed in North Dakota and Minnesota. Therefore, sug arbeet byproducts are readily available to the region's live stock producers. Two experiments were conducted to characterize the ensiling properties of wet sugarbeet pulp (WBP; 25% DM). In Experiment 1, a 4 x 3 factorial treat ment arrangement was used to define responses of ensiling WBP based on 1) formulated silage dry matter (DM) con centrations of 25,30,35, and 40%, and 2) inclusion of liq uid feedstuffs (molasses, concentrated separator byprod uct, and corn steep liquor). Experiment 2 was designed to evaluate the addition of 0.41% urea to WBP silage. In Experiment 1, lactic acid production increased (linear, P < 0.01) with the addition of all liquid feedstuffs. Though volatile fatty acid concentration was greatest (quadratic, P < 0.01) at 30% DM for molasses and concentrated separa tor byproduct, total organic acid production was enhanced with increasing silage DM only for the molasses treatment (linear, P =0.002).

Previous research has shown a differential response of sugarbeet varieties to herbicides. We evaluated the growth response of fourteen sugarbeet varieties, and four USDA sugarbeet entries (three USDA experimental hybrids and their pollinator) to postemergence applications of the micro-rate of desmedipham plus phenmedipham (1:1 ratio) at 0.09 kg ai/ha plus triflusulfuron at 0.004 kg ai/ha plus clopyralid at 0.023 kg ae/ha plus methylated seed oil at 1.5% v/v. Sugarbeets were sprayed three times at weekly intervals beginning at the cotyledon growth stage. Sugarbeet varieties differed in their response to micro-rate herbicide applications. Leaf area, fresh weight and dry weight of Hilleshog E-17 and ACH 555, two diploid varieties, were not reduced by micro-rate applications, while the leaf area of Beta 5400 and Beta 5736, two triploid varieties, was reduced by 24 and 35%, respectively, compared to their respective untreated controls. In a second experiment, the leaf area and fresh and dry weight of Spartan and Hilleshog E-17 were not reduced by postemergence microrate applications in the growth chamber or field, compared to their respective controls. Hilleshog E-38, ACH 185, and Beta 5736 had significant reductions in leaf area and dry weight in the growth chamber and field, while RH-5 had significant reductions in the growth chamber only, and tolerance was not correlated with ploidy level. Among the USDA materials, reductions in growth measures were evident in all entries; however, reductions in the experimental hybrid with SP85576 cms were markedly less for all traits except growth chamber dry weight (27% reduction in fresh weight, 20% reduction in leaf area and 16% reduction in","PeriodicalId":403165,"journal":{"name":"Journal of Sugarbeet Research","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134023311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
