New Focus on Potato: Practical Management of Powdery Scab

This presentation will aid consultants and growers in understanding how to identify powdery scab of potato and manage this disease using an integrated approach to control. Key symptoms used to identify the various stages of the disease will be described and contrasted with other similar problems. Details of the pathogen, host, disease cycle, and environmental factors affecting symptom development, will be discussed. Much attention will be given to management options for this disease including avoiding the disease, measuring the inoculum load in soil, making the appropriate cultivar selections based upon the field history, resistance of a given cultivar, inoculum levels, and environment, and utilizing specific chemical control when warranted. Understanding the full integration of several different strategies for the producer are key to managing this potentially devastating and hard to control disease.

Understanding Blemish Problems to Improve  Marketing of Fresh Potatoes - Potato Expo poster

Understanding Blemish Problems to Improve Marketing of Fresh Potatoes - Potato Expo poster

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 Grower Trials - Potato Expo Poster 2017

Crystal Green Grower Trials - Potato Expo Poster 2017

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.
