Potato Extension
NDSU / U of M Potato Scout School Registration
The NDSU / U of M International Potato Scout School will be held on February 18, 2016 at the Alerus Center in Grand Forks, ND. We will cover basic pest identification and answer any other questions you may have.
Getting the Most Out of Lorox
Presentation to the Manitoba potato growers about the use of linuron (Lorox or Linex) in potato production. This work is show how linuron can be used in a preemergence weed control program in potato to control weeds and improve marketable yield.
Research Reporting Conference & International Crop Expo
The NPPGA Research Reporting Conference & International Crop Expo will be held on February 16-18, 2016 at the Alerus Center in Grand Forks, ND. CEU credits will be available for many of the talks. We look forward to seeing you at the show.
Glyphsoate and Dicamba Drift Problmes in Potatoes
The introduction of crops resistant to glyphosate and dicamba is concerning for potato growers. These herbicides can reduce yield and quality and cause problems in tubers sold for seed. The purpose of this study is to determine the effects of glyphosate plus dicamba on plant injury, marketable yield, and the effects on seed tubers planted the following year. Glyphosate in seed potato can cause a delay in emergence, multiple stems, and malformed leaves. Dicamba can cause a delay in emergence and malformed foliage. Protect potatoes by talking to neighbors, dedicating a sprayer for potatoes, planting borders, and scouting field regularly.
Pythium Leak of Potato by Lyndon Porter, PhD
This presentation provides a synopsis of Pythium leak of potato. Growers, consultants, students and people interested in the potato industry will come to understand the pathogen, disease symptoms, epidemiology and management strategies associated with this worldwide disease of potato. Pythium leak can be a major storage disease and this presentation will discuss practices to limit issues in storage facilities. Development of resistance by the pathogen in the US to the fungicide metalaxyl will be discussed and its implications.
North Dakota Fresh Market Potato Cultivar/Selection Trial Results for 2015
Potato growers continually are looking for the next potato cultivar that provides high yield and good quality, and can be produced sustainably. Potato breeders continue to develop new potato cultivars with many desirable genetic traits. These traits may include increased yield potential, resistance to diseases, better tuber size profile, improved skin color, drought tolerance and enhanced nutrient-use efficiency. The NDSU Potato Extension Agronomy program has produced this data for red- and yellow-skinned potato cultivars/selections to assist potato growers in selecting new cultivars to produce on their farms.
Rotational Crops Effects on Potato Production the the Red River Valley
This is a presentation of the first year of a 2-year study on the effects of tillage and crop (canola, wheat, and dry edible beans) prior to potato in the Red River Valley. We plan on planting potatoes in 2016 following these crops to determine the benefit of each previous crop and tillage method on potato. This presentation discusses why previous crop is important utilizing some previous data.
New Focus on Potato "It's Significant to Me!" The Purpose of Statistics in Ag Research
Have you ever listened to a scientific presentation and heard the phrase, "but the differences were not significant"? Or have you ever wondered why researchers put letters next to number in tables or on graphs? This presentation will answer these questions. Additionally, this presentation will help viewers make sense of how information is used in relation to making claims about performance of products used in crop production. Specifically we will present examples of how data are collected from small plot and large scale research trials, show how those data should be presented, and answer the question, "is it really significant to me?"
Potato Tuber Viruses: Mop-top Management
The potato mop-top virus (PMTV) is spreading throughout the potato-growing regions in the U.S. Managing PMTV is difficult. No tests for the virus are required in the U.S. seed certification regulations to regulate PMTV. The most effective way to protect potato production is by selecting cultivars that possess tolerance to PMTV tuber necrosis. No commercially available potato cultivars are completely resistant to PMTV, but recent data indicates there are various tolerances to PMTV.
Susie Thompson Potato Breeding Handout
Field day handout from Dr. Susie Thompson, NDSU Potato Breeder. This handout covers a lot of exciting research being conducted the Red River Valley and surrounding area on the development of new potato varieties.
