1.23.2012 -- 562 - PLANTER PREPARATION - How Ready Is Yours?
The two factors most responsible for excellent results in 2012 are planting early and achieving a high plant population. Accurate seeding into a well prepared seedbed should result in about 70% of seed establishing a healthy plant. If 10 percent of the seed sown at a 4.7 inch spacing does not establish a harvestable root, losses could be as much as $100 per acre. Additional losses are likely from greater difficulty defoliating and harvesting uneven stands.

1.9.2012 -- 561 - Herbicide Resistant Weed Development and Management
Weed resistance to herbicides has been occurring for several decades in North Dakota and Minnesota. Resistance may develop with repeated use of a specific herbicide for several years or use of multiple herbicides from the same mode-of-action group throughout the crop rotation. Weed characteristics that increase the likelihood of resistance development include large plant numbers, prolific seed production, high rates of weed spread (flooding in the RRV), presence and growth in diverse environmental conditions.

11.22.2011 -- 560 - The 2011 Growing Season - A Step Back
Comments made regarding the 2010 crop at this time last year and future expectations indicate favorable growing season weather is really critical to success. The tremendous 2010 beet crop for all three cooperatives in the region was followed by probably the poorest crop for all three companies in the last 10 years. Mr. Kip Cullers a ten time national corn yield contest winner from Southwest Missouri stated. “I never learn as much from my success – I always learn from my failures”. Lets hope that holds true for sugarbeet growers in the region this year and we learn from the 2011 challenges as we go forward.

11.9.2011 -- 559 - Variety Selection For 2012
Once your field selection and fall fertilization and tillage have been completed growers must choose varieties for 2012. During my 14 years at American Crystal Sugar Company variety selection decisions seem to be happening earlier and earlier each year. In the rush to secure selected varieties, choices are made with limited coded trial data. High pressure seed sales tactics contributed to this situation. Growers are strongly encouraged to postpone 2012 seed orders until 2011 variety field performance can be verified and coded trial data is available. If ordering early keep your options open to change your selection as more data becomes available.

9.1.2011 -- 558 - Nitrogen Management: What Works and Why
Nitrogen management for sugarbeets is a very challenging problem to get just right to maximize profit. Weather patterns have a great impact on soil temperature and moisture content. Soil temperature and moisture affect many nitrogen cycle processes including; mineralization, denitrification, volatilization, and leaching. Many growers have asked whether they should apply nitrogen for beets in the fall or spring.

8.16.2011 -- 557 - Resistant Weeds: Cercospora Demand Attention
Weed resistance has been developing for a long period of time in Minnesota and North Dakota. Resistance to ALS inhibitors was first documented in ND in 1987. The first documented weed resistance in Minnesota was Common Lambsquarters resistance to atrazine in 1982.

7.19.2011 -- 556 - Prepile Revenue Exceeds Stockpile Revenue
THE PREPILE PREMIUM SYSTEM IS IN PLACE TO ENCOURAGE SHAREHOLDERS TO DELIVER A PERCENTAGE OF THEIR CROP early. This allows the Company to maximize the campaign length and fully utilize assets to maximize shareholder returns. The prepile payment system has been extensively studied and reviewed. It was revised in 2010 to ensure growers are compensated fairly for the beets delivered.

6.29.2011 -- 555 - Cercospora Control and Resistance Management
CERCOSPORA LEAFSPOT INCIDENCE AND SEVERITY INCREASED DRAMATICALLY IN 2010 COMPARED TO RECENT YEARS. THIS WAS particularly apparent in the southern Red River Valley. Early planting, above average temperatures and well above normal relative humidity levels caused many favorable infection periods for disease.

6.2.2011 -- 554 - Maximizing Weed Control in Roundup Ready®
Weed control has been made much more convenient and effective using herbicides containing glyphosate. Well over 50 herbicides containing glyphosate are registered for use in 2011. These products have 6 different levels of acid equivalent and vary widely in content of non-ionic surfactant. A brochure prepared with the assistance of Dr. Jeff Stachler, NDSU/UM Extension Sugarbeet Weed Specialist, summarizes the characteristics of each herbicide. It is available from your agriculturist.

5.17.2011 -- 553 - Weeds and Rhizoctonia: “Don’t Get Behind”
WEEDS: Soils usually warm up faster with late planting with weed and beet seedlings emerging together. When this occurs weeds compete more vigorously with beets and risk of yield loss is greater. Timing that first herbicide application is more critical than ever.
