Potato cyst nematodes (PCN) are one of the world’s most significant potato pests. Despite potentially devastating consequences on yield, symptoms are frequently subtle; the crop can just look a bit sickly or fail to thrive. This PotatoLink magazine article covers the lifecycle of PCN, impacts of PCN, and how Scotland manages PCN.

Three successive La Niña seasons have left prime potato growing areas waterlogged. Challenges for growers are evident at every stage, from managing seed, planting, crop management and storage. Paulette Baumbartl covers all the key points in this article in Issue 8 of PotatoLink magazine.

Potato growers have many options for controlling weeds, from prevention and cultural management to mechanical and physical weed control, and chemical and biological methods. With so many choices, the key to success is knowing which method to use, and how to combine them for maximum impact. Read about the weed control tool box and more in this PotatoLink magazine article.

The world may be easing its way into post-pandemic normality, however latest market research shows that this will have limited impact on the historically high prices of nitrogen and imported fertilisers for Australian farmers. This PotatoLink magazine article provides tips on getting the most nitrogen out of your legume cover crop.

As every vegetable grower understands, all good crops start with good seed, and potatoes are no exception. However, potato tubers, unlike many other seeds, need considerable care and attention to optimise results. This PotatoLink magazine special feature covers seed age, diseases, storage, cutting, treatment, and certification.

In Issue 07 of PotatoLink magazine, Ryan Hall explains that the vast majority of insects are harmless, some are beneficial and a very few are damaging to potato crops. Encouraging beneficial insects into the crop can save time and money, avoid negative side effects, and prevent development of resistance.

Powdery scab is a devastating pathogen affecting potato growers of Australia causing annual losses estimated to top $13.4 million annually. In issue 07 of PotatoLink magazine, Prof Calum Wilson from Tasmanian Institute of Agriculture reports on his 3-year project — Mechanisms and manipulation or resistance to powdery scab in potato roots.

Petiole sampling and analysis is an effective and simple way to determine the nutrient status of a crop, including diagnosing any deficiencies or toxicities in potato plants. Like any analyses, getting the sampling right is the first step. In this PotatoLink magazine article, learn when to sample, how to sample and how to handle samples.

In Issue 06 of PotatoLink magazine, Ryan Hall looks at the accessibility and mobility of technology available to growers in the form of drones, remote sensing and smartphone apps.

In Issue 02 of PotatoLink magazine, you can read the article on the CROP.ZONE Integrated weed management system used as an alternative to herbicides to terminate potato crops.

Developed by SARDI (South Australian Research and Development Institute), PREDICTA Pt is a commercial DNA testing service that can identify which pathogens are in the soil or skin of seed tubers.

In Issue 05 of PotatoLink magazine, Ryan Hall and Jenny Ekman from the PotatoLink team report on PREDICTA Pt including a 5-year case study describing its use in monitoring powdery scab and rhizoctonia on a commercial farm.

The rising costs of labour, fuel, power and fertiliser, coupled with a desire to embrace more sustainable practices, are driving the uptake of new biological and biostimulant products among potato farmers. Read more about biologicals in this PotatoLink magazine article.

Potato plants take up large quantities of potassium with peak daily uptake reaching over 4 kg/ha/day. Supplying potassium is most important during stolon and tuber initiation, although maximum uptake occurs during tuber bulking. This PotatoLink magazine article includes information on supplying potassium to crops and how potassium has helped Canowindra, NSW potatoes.

In Issue 05 of PotatoLink magazine, the Spud GP answers the question: Why are some of my spuds looking pretty ugly? As well as a comprehensive response, preventative strategies for the future are also offered.

Magnesium (Mg) is essential to plants. It is strongly involved in photosynthesis and transporting carbohydrates from leaves to roots, which is particularly important for tuber development. Yet, it may be overlooked within fertiliser programs focused on N, P and K. Read about the Mg mini trial in this PotatoLink magazine article.

Potatoes and sustainability go hand in hand, not only because carbon neutral potatoes are now for sale in the UK, but because they punch above their weight compared with other food staples when it comes to environmental impact. Discover more in this PotatoLink magazine article.

In Issue 04 of PotatoLink magazine, the Spud GP answers the question: Why are the insides of some of my tubers brown and soft? The helpful response includes a list of some of the common conditions that illustrate similarities between some tuber physiological disorders and diseases.

Growers need to prepare for the opportunities and challenges ahead that arise from carbon emission management, particularly whether they can generate carbon credits from their operations. This PotatoLink magazine article discusses this with Adrian James from Natural Resource Management (NRM) who has been tracking the evolution of carbon farming options.

Views differ as to exactly what is meant by regenerative or sustainable agriculture. It may be argued that “sustainable” implies little or no change in the farming environment, whereas “regenerative” is focused on improvement but, in reality, the terms mean much the same. This PotatoLink magazine article discusses ecocentric and technocentric approaches.

With slender margins and fierce competition, food production companies are constantly trying to find faster, more efficient, more accurate and lower cost ways to process potatoes. In this PotatoLink magazine article, steam peeling and optical sorting in potato processing is discussed.
