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 (9 min listen).
Pink rot of potato is an important soil-borne storage disease of potatoes worldwide. It is caused by the fungus Phytophthora erythroseptica and sometimes by P. cryptogea. Pink rot infection is often associated with secondary infection by anaerobic soft rot bacteria.
This fact sheet outlines the symptoms, hosts, risk factors and disease cycle of pink rot, as well as potential management options.
Soil-borne diseases present an ongoing challenge to the Australian vegetable industry, with an estimated $120 million in losses annually.
Soil-borne diseases may be caused by fungi, bacteria, water moulds, nematodes and viruses living in the soil. These pathogens are able to survive for long periods on plant debris, organic matter or sometimes as free-living organisms, i.e. not requiring a plant host. The ability to survive for long periods in the soil, and often having a wide host range, makes control of soil-borne diseases difficult.
Listen to this podcast of the the webinar recording by Dr Len Tesoriero.
Trialling different management practices, technologies or varieties on-farm is a great way to 'road test' the change before implementing at a larger scale.
Read this fact sheet for further guidance on planning, choosing sites and data collection for designing your on-farm trial. There's also a handy trial protocol checklist provided to make sure you're covering the right information.

Fusarium is a genus of common soilborne fungi. Most live as saprophytes on decaying plant matter while a few are also important plant pathogens.
While there are many different pathogenic Fusarium species, some of the most damaging diseases are caused by strains of one species complex, Fusarium oxysporum. They cause vascular wilt diseases by entering the roots and colonising the water-conducting tissue (xylem). This causes older leaves to yellow and plants eventually wilt and die.
For more information read this practical fact sheet on fusarium wilt diseases, factors that favour fusarium diseases, and management strategies.
Clubroot is one of the most potentially devastating soil borne diseases affecting brassica vegetables (e.g. cabbages, cauliflower, broccoli, kale and Brussels sprouts) in Australia. Once plants are infected there are no effective control measures.

A group of Australian growers and industry representatives recently attended the 4th biennial international spinach conference in Mercia, Spain. Among the wide range of topics presented they heard about research on key diseases with a strong emphasis on those affecting crops across Europe and North America. Some of these diseases pose a significant biosecurity risk to Australian producers while others are already affecting local crops.
Article by Stuart Grigg and Carl Young
February 14 and 15 2018 saw the International Spinach Conference converge on the Northern Hemisphere’s winter vegetable growing hub of Murcia, Spain. A contingent of 14 spinach enthusiasts from Australia comprising growers and industry representatives attended the conference and associated production tour facilitated by EGVID Pty Ltd. The largest spinach stakeholders globally attended the International Spinach Conference which has previously been held in the US, Europe and China to discuss the latest trends and issues the industry faces.
Short report by Len Tesoriero and Donna Lucas
A preliminary field trial was conducted to evaluate the efficacy of chemical and biological control treatments for damping off pathogens in spinach. We demonstrated that three fungicide treatments significantly reduced the area of diseased plants within beds, however, they did not significantly increase overall spinach yield compared to untreated controls. This is most likely due to other variables affecting plant growth in the trial area.
Watch this webinar recording to learn about the latest techniques in managing the soilborne disease Fusarium wilt in vegetable crops including solanaceous, legumes, cucurbits and sweet potatoes and to understand the latest ways of managing this disease to keep your plants in production for longer and improve yield and pack out rates.
