Physiological Age of Seed Potato
The 2011 growing year was late with late emergence and later readings in the winter test. The 2012 growing season was exceptionally early in North Dakota. There was an early planting and an early harvest. The physiological age of the seed starts when the tubers are being formed. It is influenced by variety, temperature, day length and stress etc.
Physiological Potato Seed Age Can Cause Emergence Problems
Growing conditions last year included warmer than normal temperatures and less precipitation, which increased the bruising of potatoes during harvest. These stresses increased the physiological age of potato seed. When planting potatoes, use certified seed that does not have long sprouts, sprout tubers or second growth, and/or is soft or dehydrated.
Late Blight Information For 2013
Here are some links for late blight information 2013. The North Dakota Agriculture Weather Service (NDAWN) has a nice website setup that calculates late blight severity values. The Blightline phone number for many states can be found here. And other information for growers, consultants, and others involved in potato production. This information can also be found on the left-side column of the Potato Extension webpage.
Focus on Potato Presentation: Effect of Glyphosate on Potatoes
Summary: This presentation will assist growers, consultants, and other practitioners involved in all regions of the potato industry to better understand and identify the effects of glyphosate in potatoes and how it can be managed. The presentation provides a short background on glyphosate, describes injury symptoms of glyphosate in potatoes, and details symptoms of glyphosate residues that remain in seed through storage and are planted the following year. Strategies to manage glyphosate in potato are discussed.
The Economic Commission for Europe (UNECE) to Provide a New Pest and Disease Guide
The “Specialized Section on Standardization of Seed Potatoes” of the Economic Commission for Europe, (UNECE) held its 41st session in Geneva, March 11-13 March 2013. Seed certification officials of Austria, Belgium, Denmark, Finland, France, Italy, Netherlands, Russian Federation, Spain, Sweden, Switzerland, United Kingdom of Great Britain and Northern Ireland, and United States of America attended the meeting as well as a representative of the European Union. The funding for the certification official from the US is from the US Potato Board on request from the Seed Certification and Disease Management Sub-Committee of the National Potato Council.
2013 International Crop Expo
The potato educational meetings of the International Crop Expo in Grand Forks, North Dakota held on February 20th and 21st. This article contains a summary of the various talks given by the National Potato Council, United States Potato Board, United Potato Growers of America, the potato industry, and NDSU and U of M scientists.
Effect of Glyphosate on Potatoes
A new NDSU Extension publication describing the effect of glyphosate on potatoes. This publication includes many pictures and descriptions to help growers, industry, and those associated with potato production to identify the effects of glyphosate in potato and in potato seed with glyphosate residues.
MN and ND Potato Seed Directories - 2012
The Minnesota and North Dakota potato seed directories have information about the potato cultivars or selection, acres planted, and the growers. These directories and seed directories from other states and Canada can be found on the navigation panel on the left under "Certified Seed" or at http://www.ag.ndsu.edu/potatoextension/certified-seed.
International Crop Expo Potato Presentations
The International Crop Expo was held February 20th and 21st , 2013 at the Aleus Center in Grand Forks. This contains selected reports from both days, made available by the presenters.
NPPGA Research Reporting Conference Presentations
Selected reports from the NPPGA Research Reporting Conference are available. Included are presentations from both NDSU and U of M potato researchers. Topics cover glyphsoate and potatoes, potato breeding updates, nitrogen management and acrylamide content, aphids and beetles.
