This is the sugarbeet report, bringing you the latest information from NDSU throughout the sugarbeet growing season.  Sugarbeet diseases have certainly not gone away, but there is some light at the end of the tunnel, Mohamed Khan, extension sugarbeet specialist at NDSU and the University of Minnesota is here to give us an update. Mohamed, what are some of the diseases that are affecting sugar beets right now.

Thanks for having me. It should be growing season is unique in the spring of 2022. We had wet conditions early with delayed planting, but this adequate moisture and warm conditions resulted in rapid emergence. There has not been much more diseases such as rhizoctonia rootrot to date. As I said since planting we have not had too much rain and standing water. However, we have absorbed some Fusarium yellows and growers are encouraged to identify fields with a conspicuous yellowing of leaves and plant use available resistant varieties. Were next the plant in those fields sugarbeet farmers biggest problem over the past six years is our Cercospora leaf spot, the most damaging leaf disease of sugarbeet in our area. We have invested a lot of resources in developing   a holistic system to better manage this disease. I will be highlighting progress made our field demonstration near Foxhome Minnesota on Tuesday, August 30, starting at 10am.

What are some of the topics you'll be covering at the field demonstration.

Mohamed Khan  1:27  
So since 2016, Cercospora has developed resistance to many of the individual fungicides used for its control. As such, we will demonstrate the most effective mixtures for controlling the fungus. Growers will also get to observe his strategy of using fungicides with different modes of action in a rotation program that will provide season long control of Cercospora leaf spot.

Tell us about your research with the new CR plus resistant varieties.

Mohamed Khan  1:57  
Absolutely. Over the past four years, research was done in the lab greenhouse and feel to better understand how best to manage sugarbeet varieties called CR plus varieties to manage our Cercospora leaf spot. These varieties have very high resistance to leaf spot. We know the CR plus varieties are not immune to Cercospora. They typically have significantly lower disease severity, and rather than requiring six to eight fungicide applications for Disease Control, it may just require two to four applications based on environmental conditions and pathogen population. At different times of the growing season. I will share our research observations from similar research that is ongoing in the northern end of the valley at St. Thomas as well as prosper and compare with the situation in the southern part of the Red River Valley.

Mohamed, do you have any other topics you'd like to discuss. 

Mohamed Khan  2:52  
Other eventful topics will include the use of higher water volume 15 to 20 gallons per acre higher with fungicides to control the spot and which multisite fungicides are effective and economical at controlling our Cercospora leaf spot. CEU credits will be available for certified crop advisors and lunch will be provided compliments of Betaseed and lunch will be at the foxhole in Fox home. Looking forward  to see you in August 30th but feel free to call me at 218-790-8596 any questions you may have on sugarbeet.
