8.12.2010 -- 542 - Root Disease Management: Aphanomyces
Aphanomyces root rot has been a very serious disease causing beet yield and quality losses for decades. Most serious yield losses occurred in the 1990’s. Wet and warm to hot growing conditions are most favorable for Aphanomyces development. Losses of plant population can be severe with seedling disease early in the season. Yield loss can be severe in late summer with entire fields abandoned if roots are determined to be unfit for storage. Yield losses have been significantly reduced with improved varieties.

7.28.2010 -- 541 - Early Grain Harvest Provides Opportunities
The small grain harvest should start and finish 2-4 weeks earlier in 2010 than some recent years. The early harvest will provide an opportunity to complete many additional field work operations this year. Benefits should be improved crop yields and on-farm profit.

6.24.2010 -- 540 - Cercospora Control 2010
Cercospora remains our most serious foliar disease of sugarbeet in Minnesota and North Dakota. Although yields losses have not been widespread in recent years properly sequencing fungicides can definitely enhance productivity and profitability of your crop. Improper fungicide use strategies can negatively impact crop yield and quality, suitability of the crop for long term storage and reduce revenue.

4.22.2010 -- 537 - Root Disease Management: Fusarium
Fusarium was first identified about 20 years ago in the Red River Valley. At that time the disease was a novelty and caused no economic loss to sugarbeet producers. The disease increased in incidence throughout the 1990's. Disease severity increased to the point of causing economic losses early this century. Yield loss has become so severe that fields have had to be abandoned in each of the last four years. Storage losses of sugar are very severe with Fusarium infected roots in piles. Fusarium can affect the crop from right after emergence up until harvest.

3.23.2010 -- 536 - Root Disease Management
The NDSU-UM Production Practice Survey asked the question "what is your most serious production problem since 1969." The answer 95% of the time was weeds. The answer after the 2009 crop year was root diseases. It would be very safe to predict that root rots will continue to be the most serious production problem for many years into the future.

3.9.2010 -- 535 - N Fertility for Roundup Ready® Varieties
The switch to Roundup Ready® sugarbeet varieties will be over 90% in 2010. Many have questioned if there is a need to change agronomic practices when planting Roundup Ready® varieties. Frequently asked questions have been 1) how much N fertilizer do they need 2) what seed spacing is best 3) are they more susceptible to diseases? The general consensus from researchers across the nation is beets are beets no changes needed.
