Technical Abstract: More than half of the US sugar beet, Beta vulgaris, crop is produced in North Dakota and Minnesota . The objective of this research was to determine the effect of fungicides on sugar beet yield and quality in the absence of disease. Sugar beet was planted at Prosper, North Dakota in 2005, 2006 and 2007. The variety selected was tolerant to Aphanomyces and seeds were treated with Tachigaren to give additional protection from Aphanomyces. Weeds were controlled using recommended practices. Five fungicides, Eminent, Headline, Gem, Super Tin and Topsin, were each applied three times at about 14 days intervals beginning in late July. There was also an untreated control. Roots were harvested in late September. There were no significant differences in recoverable sucrose or sucrose concentration between the untreated control and any of the fungicide treatments. In 2007, root samples were collected, washed, placed in polyethylene bags, and stored at 4ºC and high humidity. Postharvest storage respiration rates were determined after 30 and 90 days in storage. There was no significant difference in respiration rate between the untreated control and any of the fungicide treatments. In the absence of disease, there was no apparent benefit in applying fungicide.
