I found this interactive temperature map and it prompted a post to direct ATGA members to the GrowWIKI. (Prompt, prompt)
This only uses a selection of Capital Cities but it only takes a small bit of shifting to suggest that Manjimup 34°.24 is almost on the same latitude as Adelaide 34° 92. Concrete and traffic laden cities are different of course to nice green countryside. (Read the background in the box that pops up “What about…” to see the maps modelling). But given another 80 years most of our children will be living in major cities if the trends continue, so this may be just an idea of what your kids summer will be like while they’re waiting for the weekend to get back to that truffle paddock their parents left them.
It’s the winter temperature ranges we’re more sensitive to for truffle growing, we need cold hours to force the ripening and the WIKI has that data.
Below is our ‘ideal’ growing areas overlay-ed in green on an average winter temperature map from the Bureau of Meteorology.
As always, higher altitude changes suitability and coastal areas are often tempered by the sea mass (which means they are subject to oceans warming).

Truffle Pest & Disease project – Research extension – Winter 2017
To update Australian truffle producers on progress and future plans within the RIRDC project “Pests and diseases of truffles and their host trees in Australia”.
The road show
Team members of the Pests and Diseases Project will visit regional centres of truffle growing districts across Australia (see proposed itinerary below).
At the talks, there will be hands-on pest collections to demonstrate the array of pests, beneficial and benign agents found in Australian truffle orchards. At these ATGA Member only meetings, you are invited to bring to the samples of any pests/diseases they want to discuss and/or identified (except at Dandenongs and Sutton meetings which will be held on truffières).
Growers will have the opportunity for direct interaction with project team members.
Because the meetings are at the same time of year as truffle harvest and sales, the sessions are proposed to start at 2.00 p.m. and go no longer than 2 hours.
As well as attending these meetings, Stewart Learmonth from WA will be requesting visits to truffle orchards during harvest to further build knowledge of pests.

This week a purveyor of truffles and fine food attempted to import some new season Tuber magnatum of Italian origin into Western Australia, only to be advised their entry was not permitted. The importer remonstrated with the Quarantine Officer that he had been importing T. magnatum into WA and other States for years without problem. The Officer held his ground and produced a copy of the “West Australian Organism List”. This document of the WA Department of Agriculture and Food lists all foods and organisms which can be imported into the State. If it’s not on the list, it can’t be imported unless a special permit which complies with various phytosanitary requirements and provenance is purchased and granted. The only truffle species that can be imported from interstate, or over-seas, without that special permit is Tuber melanosporum. The other States allow a variety of Tuber species including magnatum.
It appears previous imports of T. magnatum may have contravened WA quarantine regulations and WA Quarantine are now strictly observing the rules. So if ATGA Members (or anyone else, for that matter) are thinking of importing T. magnatum into WA for personal or commercial consumption they would be well advised to check out the WA Quarantine website or ring for advice before ordering their truffles.
In the meantime, Members of the TPWA Executive have applied to have T. magnatum and T. borchii included on the WA Organism List. Given these species are allowed into the other States it is expected that the updating of the list will be a minor formality that should be executed presently.
In his summary in the Sunday afternoon session our ATGA President Peter Stahle reviewed what he had chosen as the highlights from the presentations on the weeekend. These were what he considered are going to become significant industry issues requiring forward planning, collaboration and especially research. There will be a full video report of Peter’s talk with all the speaker presentations in our Members area, but this will give you a good overview of what we covered in Manjimup.
If you were there you may have some further comments we’d love to hear, just add them below. If you couldn’t attend we’d still like to get your feedback (although you might like to wait for the full versions.
Gavin Booth – A dose of reality
To ‘future-proof’ the industry, Australian truffle growers need to be self-sufficient organizationally and financially. There are challenges on both these counts. This season, Australia-wide, without engaging economic multipliers, at the farm gate we are an $8m industry (≈12.5 tonne harvest weight, ≈8.75 tonne saleable product, average farm gate price 75¢ – $1.00 /gm.). This doesn’t allow much room for investment in research and development in production methodology or marketing. To really make a difference, we have to find ways of leveraging our limited funds.
Vittorio Giordano – International Trade
Urbani Truffles is the largest purveyor of fresh truffles and truffle products in the world, and since 1852 this family-run company has developed markets and exports to 68 countries. The company has invested heavily in marketing truffles globally, in particular in the US where only 5 years ago 50% of Americans thought truffles were chocolates. The company recognizes the ongoing need for the industry to globally promote truffles and educate consumers, and the Australian industry has an important collaborative role to play in this. The Australian industry needs to be aware of how its marketing and pricing in overseas markets has the potential to effectively commodify this elite and special product. Now as a major producer, the Australian industry needs to be aware of the global context and impact of its sales. Australia is not a competitor to other truffle producing countries and needs to be aware of shared interest in promoting the sale and consumption of truffles globally.
Celeste Linde – Update on truffle science
Celeste gave an overview of changes and updates in the Australian truffle industry, from the perspective of a professional mycologist passionately engaged in the development of the Australian industry and providing scientific and technical advice. Her observations include:
Tuber maculatum is becoming more common in truffières in both Australia and New Zealand where it has been known as an ectomycorrhizal associate of several species of European trees since the 1960s. More recently it has been most likely spread as a contaminant of mycorrhized tree sales. All tree samples sent to the Linde Laboratory are assessed for T. maculatum and other common undesirable fungal species.
Tuber brumale is now recognized as two biotypes emanating from Eastern and Western Europe. T. brumale introduced deliberately and accidentally into Australia and New Zealand is of the Eastern European biotype.
Celeste is collaborating with French mycologists to further the understanding of maternal and paternal genotypes of Tuber melanosporum and their impact on truffle production. T. melanosporum exhibits heterothallism whereby female elements (ascogonia) become truffles and male elements (conidia) produce sexual spores of hyphae.
Understanding the sex life of truffles is fundamental to understanding truffle production and it is further complicated by some truffle “plants” being hermaphroditic (♂ & ♀), some dioecious (either ♂ or ♀), and some trioecious (♂ & ♀, and ♂ or ♀).
Stuart Dunbar – The Dunbar truffle
Stuart proudly presented the background story and images of the world’s largest T. melanosporum harvested from his Gembrook property. The truffle, now reverently referred to as “The Dunbar”, will henceforth lend its name as a descriptor of extraordinarily large truffles. (the joke was the new grading standards now include ‘Dunbar’ between Premium and Extra class).
Victoria Taylor, John Harvey and Ingrid Smith – Realities and future proofing the industry
Discussions ranged around the various state and federal government grant schemes that are available to agricultural commodities, such as truffles, to support R&D. The truffle industry has been supported by Rural industries Research and Development Corporation, since its inception in the 1990s. The industry is on notice though, that RIRDC is looking to wind up its generous support by 2019 when the 5-year truffle industry R&D strategic plan will sunset. In the meantime there are state government initiatives, such as WA’s Agriculture Produce Commission, which can raise funds for the industry through a “Fee for Service” mechanism and administered by a Producer Committee. Ultimately, the truffle industry will need to raise a levy from producers to fund R&D. This levy could be administered by RIRDC, which would obviate the need for the creation of a “Truffle Industry Research and Development Corporation”. The levy will need to operate under 11 principles, which include: demonstrated need, market failure, majority industry support and public good. The industry is encouraged to start planning for a levy now, since even with the best intent a levy can take several years to put in place.
Rohan Prince – Latest irrigation studies
Rohan is from the Department of Agriculture WA and presented a comprehensive overview of the role of irrigation in managing a truffiere. He also elaborated on the various soil moisture variables and the equipment that can be used to monitor them. As yet a causal relationship between soil moisture and truffle production has not been established. This is a topic worthy of industry investment in the future.
Jan de Jager – Using fertilizers
Jan highlighted the complexity and importance of soil ecology in achieving ideal growing conditions for any crop, including truffles and their host trees. To maximize production of truffles there are many soil variables that need to be taken into account, many of which can be simply adjusted/improved through the addition of mineral supplements. Jan threw down the gauntlet to the industry to back research into the use of organic fertilizers to improve soil conditions.
Stuart Learmonth and Anne Mitchell – Pest and Diseases
Stuart provided an update on the Pests and Diseases project that is being conducted nationally. The project is essentially being run in 3 parts: a survey of growers, “My Pest Guide” reporting and technical information transfer. The Research Team led by Stuart and Anne is consolidating and interpreting information gained directly from growers. A comprehensive update on the research can be found at the ATGA website.
George Wilkinson – New Zealand’s 2016 season
George presented an update on the 2016 season in New Zealand where the aggregate harvest (all species) is estimated to be 0.5 tonne. T. brumale production exceeds T. melanosporum. The New Zealand industry is keen to emulate the Australian promotion of truffles through festivals held in the major cities.
Fred Harden – GROWwiki
Fred, the ATGA Webmaster, is developing a comprehensive growers’ guide for T. melanosporum. Fred demonstrated the interactive graphics and information access that will be a feature of the website, which will be based on a Wiki platform to facilitate regular updates. Components of the guide are now live and can be accessed through the ATGA website. Sign up to add material, comment and help build a definitive guide. The website is available via the Members Area menu or direct at grow.trufflegrowers.com.au
Reports on the other speakers, the Workshops and Field trips will all be online soon with the full conference report.
The latest Farm Biosecurity newsletter from the Farm Biosecurity Program (which is a joint initiative of Animal Health Australia (AHA) and Plant Health Australia (PHA)) is online here now.
Of interest to Truffle Growers is the final video in the Program’s ‘Biosecurity Essentials’ series. It’s called Biosecurity practice helps make production perfect
and it features friend of the ATGA Alison Saunders (our contact at RIRDC for many years) and a Hilltops NSW premium quality walnut and chestnut producer. Alison was a speaker at our 2013 Mittagong Conference and AGM.
The video provides a valuable insight into the type of activities you can do, every day, within the structure of your daily farm management routines to enhance biosecurity. If you’re into videos, remember the FarmBiosecurity YouTube Channel . It features lots of people with Akubras who know their stuff.
