The diseases caused by Spongospora subterranea (tuber powdery scab and root hyperplasia) can cause significant yield and quality loss. Not all soils are equally susceptible to this disease. This 2020 report determined factors that resulted in Spongospora suppressive soils in New Zealand.

This guide produced by RMCG in 2020 was based on current knowledge on management of powdery scab, highlighting key factors that affect the risks of this disease and opportunities for effective disease management.

With a growing interest in the area of soil health and the wide range of products available, this fact sheet explores organic soil amendments, biologicals and biostimulants to help growers understand what these products are and how they work.

Explore the impact of hydrophobic soils on potato production and options for growers to assist with their management to improve potato yields.

The Australian potato industry is committed to building its capacity to respond to potential biosecurity threats. In addition to dedicated farm biosecurity officers and advisers, a range of farm biosecurity planning resources are available for growers, advisers and industry members to access. These resources are regularly reviewed and updated to reflect industry needs.

‘Know your salts’ takes an in-depth look at salinity and the salts that affect both plant health and soil structure, and guide potato nutrition.

This first fact sheet outlines the causes of salinity followed by key assessments and tests that will better inform your management decisions.

Learn about using the IrriSAT technology which combines evapotranspiration (ETo) and satellite imaging, and how to link this with data from direct soil moisture sensors, to help you schedule irrigation.

This NSW case study has shown that IrriSAT satellite images, used to monitor irrigation, can also help potato growers identify soil and irrigation problems across the pivot. Fixing the problems identified in this case study would have increased yield and revenue by between $7,600 and $10,800 under this half pivot.

This case study explains how the irrigation tool, IrriSAT, combined with soil moisture monitoring, provided important information to the grower about crop water requirements and actual soil moisture levels. This enabled him to manage his crop irrigation to maximise yield and quality.

Management of rots, both in the field and post-harvest, is an ongoing challenge for potato producers. Agronomists Marc Hinderager and Dr Pieter Van Nieuwenhuyse discuss a trial that was set up to explore the effect of sanitisers and/or drying on the development of post-harvest bacterial soft rot in potatoes.

Plant analysis is used as a tool to fine tune the nutrition of crops. The nutrient status of plants or parts of plants can be determined directly via laboratory analysis or estimated via in-field testing, while the overall health and nutrient status of a crop can be assessed via non-destructive sensing technologies.

Potato virus Y is a major issue for potato production in all Australian states and, indeed, worldwide. However, it exists as a complex of different strains. This summary talks about the latest identification of PVY found in Australia.

Find out more about good salinity management practices on farm, salinity thresholds for vegetables, how salinity can be identified and measured, as well as appropriate EC ranges for soils and water. 

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.

Hear from industry experts on how strip-till will save you fuel and time, increase soil organic matter, reduce erosion and compaction, and how fertilisers’ can be banded at multiple depths.

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.

Integrated weed management (IWM) is about combining a series of small management changes to produce a big result. Read the guide that was conducted by the University of New England through the Hort Innovation funded project.

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.
