When Selecting Seed, Consider Silver Scurf
Selection of potato seed is one of the first steps to a successful potato production to maximize yield potential. Identifying and purchasing high-quality seed will encourage vigorous growth and healthy plants. If a seed lot is suspected to have silver scurf the disease, tubers can be sent to a laboratory to confirm the presence of the disease. This is done by placing the tubers in a humid chamber for two to three weeks then assessing the tubers under a microscope. This article contains information and management tips on silver scurf.
Best of the Best in Wheat and Soybean Research
The North Dakota State University and the University of Minnesota Extension Services, along with MAWG, MWR&PC, MSR&PC, NDSC, NDGGA, and NDWC have joined together to present producers with current research information. In this day-long workshop, growers will have the opportunity to learn from researchers and extension specialists. These sessions are Free. Pre-registration is encouraged. To register call, (800) 242-6118, ext 3 or go onlineat www.smallgrains.org and click on Best of the Best link.
Identifying and Assessing Delayed Emergence and Reduced Yield from Glyphosate Residues in Seed Potato
Seed potato fields can unintentionally come into contact with glyphosate by physical drift, contamination of spraying equipment, inversions, or misapplication. Glyphosate translocates to the daughter tubers and can be stored there until planting the next spring. This results in delayed emergence when potato seed is planted the next growing season. Symptomology of potato clones with glyphosate residues may include erratic emergence, malformed leaves, multiple shoots from a single eye, and enlarged shoots.
Using the Web to Stay Informed—Potato Extension Style!
Technology has provided us immediate access to information, allowing us to research various topics, conduct business, make business decisions, and connect with friends and family. To provide easy and immediate access to information for those in the potato community, I have started a webpage (www.ag.ndsu.edu/potatoextension), Facebook page (www.facebook.com/potatoextension), Twitter account (www.twitter.com/spudology), LinkedIn account (www.linkedin.com/in/spudology), and Pinterest account (www.pinterest.com/spudology). I welcome questions or comments on any of these. Additionally, if you would like to receive emails there is an email signup on this webpage. Emails will be used to send out notifications of important information.
Documentation for Suspected Spray Drift
Herbicide drift to nontarget plants can cause damage sufficient to result in a significant monetary loss. Documentation of chemical damage is required if compensation for loss will be pursued. In addition, establish the source of drift and amount of loss caused by the damage. NDSU Extension publication WC-751.

Potatoes could become a feed option for cattle this year
Potatoes could become a feed option for cattle this year. Drought conditions led to poor yields in forage crops, high hay and corn prices, and a larger supply of diseased or malformed potatoes. Livestock experts say potatoes have similar feed quality as barley on a dry-matter basis and could be a relatively low-cost feedstuff, but the cost of transporting them could be high, and cattle should be adapted slowly to rations containing potatoes to avoid digestive upsets.

Poster on Linuron Tank Mixtures at Potato Expo 2016
Timing of herbicide application can be the difference in having a one-pass weed control system or needing multiple herbicide applications. Linuron can provide beneficial weed control in potato, especially when tank mixed with other herbicides. It can provide control of hard-to-control weeds such as common lambsquarters, red root pigweed, and night shade species. The purpose of this project was to determine the effects of linuron plus metribuzin or rimsulfuron treatments on crop injury and marketable yield.
Linuron poster at Western Society of Weed Science
Timing of herbicide treatment can be the difference in having a one-pass weed control system or needing multiple herbicide applications. Linuron can provide beneficial weed control in potato, especially when tank mixed with other herbicides. Linuron provides control of hard-tocontrol weeds such as common lambsquarters, red root pigweed, and nightshade species. However, aerial applications are not allowed and it does not work well in soils with high clay content or high organic matter. It may be advantageous because it may cause less damage to potato plants as they are emerging when compared to other herbicides.
