Potato Rotation Restrictions for North Dakota
Herbicide carryover in soil can affect potato planting in many fields. This table gives plant back restrictions for North Dakota. Please see the NDSU Weed Control Guide for more information on herbicide carryover in other crops (http://www.ag.ndsu.edu/weeds/weed-control-guides/nd-weed-control-guide-1).
International Crop Expo Potato Program
The International Crop Expo will be held February 20th and 21st at the Aleus Center in Grand Forks. The show floor is once again sold out, making it one of the biggest ag shows in the valley. Keynote speaker will be Michele Payn-Knoper at 1:00 p.m.on Wednesday. The topic will be "Celebrating Agriculture... from the farm gate to the consumer plate." For a complete list of events and times, including bean and small grains programming, log onto www.cropexpo.com. The following is the potato programming schedule for the International Crop Expo.
NPPGA Research Reporting Conference
The Northern Plains Potato Growers Association 2013 Research Reporting Conference will be held Tuesday, February 19 at the Alerus Center in Grand Forks. It is free and open to the public.The moderator will be North Dakota State University/University of Minnesota Potato Extension Agronomist Dr. Andy Robinson. The following is a schedule of the day's events.
Off-site Movement of 2,4-D and Dicamba in Soybean and Glyphosate in Potatoes
Learn about the effects of 2,4-D and dicamba drift in soybean! The presentation covers crop injury, yield loss, and predicting yield loss using crop injury ratings. It also covers the effects of glyphosate in potatoes. Contains pictures of the effects of glyphosate residues in seed potatoes planted the following year.
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.
