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.

Tospoviruses cause large losses of product across the supply chain. Whilst some species such as Tomato spotted wilt virus (TSWV) are present in Australia, others are not and represent a significant biosecurity threat. This 2019 report compiles important DNA information that could be used with modern biotechnology to develop new and effective controls.

This Hort Innovation report goes into a needs analysis of the potato industry. It highlights that there is a need for strong extension and communication programs. It also develops a strategy and implementation plan that could be used to meet those needs.

This Hort Innovation report covers the current state of knowledge of soil health, with the use of over 220 references from both Australian and international sources. This report also covers various workshops media articles, videos and a factsheet associated with soil health in potato production.

This Monitoring Psyllids and Psyllid Predators in Australian Potato Crops report by Tasmanian Institute of Agriculture (TIA) and Hort Innovation covers the different psyllid populations found and the levels of psyllid predators present.

This Serve-Ag project ran from 2016 to 2020 to assess groundwater quality in areas of potato production in South Australia (where groundwater quality is most variable) and investigated how regional and seasonal water-quality variability impacts on potato production and quality.

Powdery Scab, caused by Spongospora subterranea, is a costly blemish disease. This 2018 report delves into novel detection and mitigation strategies. Both greenhouse and field trials were undertaken. This report has provided a great source of knowledge for the ongoing battle with Spongospora.

This Hort Innovation report reviewed the Australian potato industry seed handling and seed quality. The latest trends and research were investigated.

This 2018 report looks at the available literature and information regarding species present in Australia. It also investigates the accessibility of accurate diagnostic tests.

This Hort Innovation report covers the efforts made to maintain a large bank of different potato varieties, and what they are good for. Specific focus was made on viral resistance, disease resistance, specific gravity and various cooking factors. Potatoes from Europe to America are included in this potato bank.

A three-year project in Tasmania was conducted on the potential benefits of using degradable polyethylene films in potato crops. This 2013 report found there was limited benefit to nitrogen fertiliser savings and yield but instead may allow for early harvest and some water saving.

This Hort Innovation report explores the genetics behind breeding new varieties of potatoes. The report looks into developing genetic analysis tools to improve cultivar selection and development. With a focus on improving resistance to potato cyst nematodes and potato virus Y this 2012 paper provides great insight into how new cultivars are chosen.

During the 1990s the SA processing potato industry expanded rapidly, developing a range of crop monitoring and management tools. This 2006 Hort Innovation report refines and brings these together, with specific information on plant nutrition, pest and disease management and irrigation.

This 2005 Hort Innovation study involved a survey of packers, supply chain monitoring and storage trials. Storage and transport temperatures ranged from 4C to ambient, with washed potatoes more likely to be cooled that brushed or dirty potatoes.

Soil insects are difficult to detect and can cause blemishes on potatoes that may reduce quality. This 2005 Hort Innovation report sets out guidelines on monitoring soil insects and potential management strategies that could be implemented.
