A report on red- and yellow-skinned potato cultivar trial conducted in Big Lake, MN. Information on potato graded yield, tuber number, stems per plant and vigor estimation.
Lenticels in potato tubers are an unsightly blemish. These blemishes may reduce marketability of tubers and be an entry point for pathogens. Learn about how lenticel spot is caused and tips on managing this disorder.
The MN Area II Potato Growrs 26th Annual Educational Workshop will be held on March 1, 2017 at Jack and Jim's Event Center in Duelm, MN. This workshop gives us the opportunity to get together, learn and share ideas. We feel this program will be useful to everyone in the potato industry. We hope to see you there.
There has been much interest for the upcoming Potato Scout School. To attend, registration is required because the room size will only allow 50 participants. Registration fees will help cover costs for the room, lunch, and materials. CEU credits will also be available.
The scheduled speakers and times are now available for the NPPGA Research Reporting Conference and International Crop Expo. The program planned is exciting and full of great content that will update potato growers about recent research and cover topics of importance.
A challenge fresh market potato producers have is to produce tubers free from blemishes, because consumers “buy with their eyes” as they naturally gravitate to tubers free from blemishes. Smooth-skinned tubers are especially vulnerable to blemishes. This project conducted a survey to determine the major blemish problems, determined the effects of various chemistries on blemishes, and evaluated the effects of blemishes on newer cultivars. The most prevalent blemishes were skin netting and external bruising. Some fungicides reduced black dot/silver scurf blemishes. Those that were most consistent were Emesto Silver, Quadris, Nubark Mancozeb + Moncot 70 DF and Maxim 4 FS.
Crystal Green is a struvite-based, registered fertilizer. Due to the citrate soluble properties of this mineral, nutrients are only released when in the presence of actively growing roots. Grower trials were conducted in 2015 and 2016 to evaluate the effectiveness of a struvite product, Crystal Green on irrigated Russet Burbank, Umatilla Russet, and Bannock Russet potatoes in Minnesota and North Dakota. In general, there was a positive response to Crystal Green when potatoes were grown in alkaline or acidic soils. Potatoes grown in neutral pH did not have a positive response to Crystal Green.
White mold is one of several important foliar diseases that potentially affect potato production due to reductions in tuber yield and increase disease management costs. This presentation will help potato growers and field managers in potato production regions understand how the fungus that cause white mold colonizes host substrates to initiate disease, infects healthy potato foliage, and is most efficiently managed. Environmental and host factors that affect disease spread and progression will be discussed. The rolls of sclerotia in overwintering of the pathogen, of apothecia and ascospores in disease spread, senescent host tissue for initial infection and how they all relate to disease management will be presented. By the end of the presentation, those that listen will know more about the epidemiology of white mold and will be well equipped to manage the disease.
This presentation gives an overview of the effects of planting canola, dry bean, or wheat prior to potatoes. Data from the first potato crop is available and did not have any significant differences in yield or marketable yield.
The National Potato Council has received a number of calls and other contacts regarding the presence of Dickeya in North America and particularly with regard to the role of laboratory testing in making determinations on the presence of Dickeya in seed potato. Here is some information on these topics. This letter came from the NPC.
