SUGAR ENDS AND stem-end chip defect are tuber disorders affecting product quality of processing and chipping potatoes, respectively. The environmental stresses causing the disorders occur during the growing season, but tubers appear asymptomatic until harvest or later in storage. Although there are many similarities between the two disorders, there are also some key differences. To understand the factors causing sugar ends and stem-end chip defect as well as management practices to reduce…
COMMON SCAB, a bacterial disease that doesn’t affect yields but causes ugly lesions and cavities on infected tubers, which can render them unmarketable, is a pervasive threat in potato-growing areas across Canada. It has likely been around for as long as people have been growing potatoes, but researchers are still trying to determine why the pathogen is much more common in some fields than others and what the best methods are for…
Although the transmission and incidence of Potato virus Y in Canadian potato crops has declined dramatically over the past eight years, new threats to quality and yield are on the horizon in the form of necrosis-causing novel strains. How can Canadian growers manage PVY on their farms today, and how do they fight these latest strains? For this edition of Roundtable, Spud Smart sought input from industry experts Mathuresh Singh, director of Agricultural…
Remote sensing in potatoes is being actively investigated for its value in ensuring a high-yielding, healthy crop. Although in its relatively early stages in Canada, data collection through remote means and the related data analysis is developing at a swift pace. In this edition of Roundtable, Spud Smart gathered experts to report on the remote sensing tech being used in potatoes, the present value of the information collected and where the future…
Ideal growing conditions, optimum fertility, pest and disease control – all these things are crucial to ensure a high-yielding, healthy crop. But before the seed goes in the ground, it’s crucial growers ensure the seed they’re planting is as healthy as possible. For this edition of Roundtable, Spud Smart gathered some expert opinions on why it’s important potato growers plant the best seed they can get their hands on. Our five experts…
Potato is the most important non-grain crop in the world. So, understanding the potential impacts of climate change on potato production is critical, especially for producers. Throughout its long history, Earth has warmed and cooled time and again. Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past…
The case could be made that caring for potatoes and for children have a lot in common: Let your guard down for a minute and you’ll pay for it in the end. Like parenting, potato storage is an area in which expert advice can save a lot of headaches and wrong turns. In this edition of Roundtable, Spud Smart turned to three experts on the ins and outs of potato storage: Robert…
Soil health can be seen as the continued capacity of the soil to function as a vital, living ecosystem that sustains plants, animals and humans. This definition from the U.S. Department of Agriculture – Natural Resources Conservation Service (USDA-NRCS) speaks to the importance of managing the soil so it can continue to sustain life for future generations. According to the USDA-NRCS, there are a number of agronomic measures farmers can follow to…
For potato farmers, soil-borne pests and diseases are like that pesky younger sibling that’s always trying to get you in trouble: ignore them at your peril. Hazards such as Verticillium, nematodes, pink rot and Rhizoctonia can have a big impact on the bottom line if not kept in check. For this edition of Roundtable, Spud Smart sought input from three industry experts on the financial importance of these potato problems, and best…
Fall bedding in potato fields allows for soil preparation work to be done when growers typically have more time and labour available to them. In this system, growers usually irrigate, broadcast fertilizer as needed, plow, and then form beds into which they plant the following spring. For this edition of Roundtable, Spud Smart asked the following five experts to weigh in on their experiences with fall bedding. Louis Claassen, a potato producer…
