Season draws to a close... Slow and steady might typically win the race, but for grape growers this season that hasn’t quite been the case. The mild season has had its challenges for both dried and table grape producers across the country – off the back of an already difficult season last year. Labur and weather have both played the role of the antagonist, but a few good characters have entered the narrative. New projects and new varieties are showing promise for both industries, and events are resuming. It’s great to see familiar and new faces and rebuild the connections of industry which may have drifted due to isolation. I’m sure many of you are ready for the season’s end – we hope you can all enjoy a break soon! – from the team

met with a concerning sight. Random vines appeared stunted – with short zig-zagging shots and leaves forming small cabbage-like clusters – and many of the shoots had a very distinctive browning of the pith. Inflorescences on affected vines were typically small and appeared frosted or had already aborted. The symptoms in affected vines resembled damage caused by mites, virus, frost or nutrient deficiency, and weren’t just exclusive to a few varieties – several varieties were affected, some more than others.
The ATGA team responded immediately, assembling experts from across the nation to engage in “think-tanks”. The team also requested an amendment to the Hort Innovation-
With symptoms growing out and harvest just around the corner, the team was on borrowed time to understand the condition.. But where would they start? The quest for answers started not dissimilar to jumping down a rabbit hole. “Agronomists, consultants, pest scouts and researchers shared insights about whether a range of different management practices might correlate with the occurrence of RSG,” project lead Alison MacGregor said. “And researchers shared experience in viruses, phytoplasma,

likely to cause significant economic loss through poor bunch counts in the 2022 harvest, raising the concerns of the ATGA team. However, it wasn’t the first time it had been reported. Referred to as restricted spring growth (RSG), the condition was reported in wine grapes in Sunraysia in the 1990s. It also resembles delayed spring growth (DSG) reported in 2019 in table grapes in the United States. DSG has been attributed to temperatures, water and carbohydrates.

“We also looked further afield, for reports of similar symptoms in the United States, Europe and South Africa. “One thing was clear. We should first check for pest and disease, in case there was a pathological cause.”

Initial testing looked at viruses.
Phytoplasma had been suspected of causing RSG in Sunraysia in the early 2000s , but the link was never proven. ATGA didn’t want to overlook phytoplasma as a cause of RSG in 2021, and sent 25 shoot samples to Dr Fiona Constable at Agriculture Victoria for phytoplasma testing.
Agriculture Victoria tested the
Grape producers were already concerned about Grapevine Pinot gris virus (GPGV), and symptoms of RSG matched symptoms previously seen on vines positive for GPGV.

Verdict: None of the bacteria or fungi or yeasts cultured from these samples were pathogenic to grapevines.

ROOT DISEASE AND SOIL PATHOGENS The roots and soil balls from six of those sampled vine trunk were sent to Agriculture Victoria to test for soil and root pathogens. Several fungi and bacteria were isolated from the roots and soil, including Alternaria, Aspergillus, Mucor, Penicillium, Trichoderma, and Pythium.

ATGA CHAIR & CEO
Weathering the storm News from our chair As a grower, exporter, and labour hire provider, this harvest season has been a perfect storm of events. Thankfully, we are almost through the season, but it hasn't been without its tests. There were some growers who were lucky to escape the full brunt of the mild weather, but even those up north with earlier seasons experienced challenges. I can’t remember a year that my Crimson Seedless coloured as late as it did this year. I put that down to the milder season, and the humidity we experienced throughout January and February. The lack of supply of labour means people are screaming for backpackers everywhere – in cotton, blueberries, there is so much choice. Those jobs would normally have to be fought for. If you applied for a job in cotton you’d have to compete with 3000 backpackers. Now, there simply aren’t enough to go around, and competition from other industries has had an effect. I have paid my workers a good hourly rate but they’re still ready to go elsewhere because the season’s nearly at an end – even though we’ll need workers for pruning. However, looking forward, I hope chemical and fertiliser supply will get
back into a pattern, and everything in short supply will ease up before we move into next season.
News from our CEO Unusual weather conditions, Covid, and seasonal labour have led to an unexpected and very challenging season. Talking to growers and exporters, everyone has been faced with different circumstances that have significantly impacted the current harvest season. Covid has been a catalyst for many of those challenges. It’s no secret that the increasing cost of containers, treated pallets and freight shipping logistics have proved difficult for all exporters and growers. The seasonal harvest labour workforce is still a major worry for most growers, with estimates the industry has been short of labour by 50 per cent of its normal requirement. Of the workers available, many are picking and choosing which property to go to and what they will harvest. The ATGA has invested a great deal of capital resources in attempting to attract seasonal workers, producing resources for seasonal workers and hosting regular meetings with harvest labour providers, stakeholders, and the Victorian Government. One of the priorities the ATGA has been pushing with state and federal bodies is
Jeremey Boyd | Chair

the regulation of labour hire contractors (LHCs). Until governments get together to have uniform regulations for how LHCs operate, then issues with labour supply will continue to surface and be problematic for growers. Let’s hope the governments act on this soon. The Federal Government recently made a positive announcement, with news that one country had finally signed on to the new Australian Agriculture Visa (Ag Visa). However, that has been of no benefit to the industry this year and there is still a great deal of uncertainty around the successful implementation of the Ag Visa going forward. It is definitely something our industry cannot rely on going forward until there are more tangible announcements. The climatic conditions this year have also not helped, with very cool weather during spring and very little sunlight. Maturity sampling and retailer data, collected as part of the ATGA’s maturity project, along with a consensus of opinion, show this season’s late maturation, slow colouring and berry softness is likely related to these climatic conditions. Late maturing of grapes in all regions meant consumer acceptability of grapes declined to worrying levels, where 50 per cent of consumers were not repurchasing within 12 weeks of a poor eating experience. Let’s hope this has been a one-off occurrence and the industry regains its status in the coming years. You can read more the maturity project updates on pages 14-15. v

number
The application of flower and fruit recognit ion techniques based on artificial intellige nce provides the opportunity to estimate several crop parameters in orchards. Howeve r, only a few compan ies have commercial groundbased or aerial platform capable of accurat s ely predicting crop parameters. The Australian based company Green Atlas targeted this market gap and recently developed Cartographer, a groundbased mobile platform that has been success fully used to rapidly scan commercial orchard s and produce flower and fruit counts in apples. Scanning with Cartogra pher can very quickly produce a ‘relative heatmap’ of flower and fruit number per tree that clearly shows the variability across an orchard block. For more accurat e determination of the absolute number s of flowers or fruit, Cartographer requires calibrati on for a specific block. Calibrat ion requires groundtruth counts of flower clusters and fruit in calibration zones. In most cases, spatial and tempora l variability within orchard blocks can be determined by simply assessing uncalibr ated spatial maps.
Flower and fruit variab ility in ‘ANP-0131’ pears
The blush pear cultivar ‘ANP-0131’ produce s fruit with superior texture, flavour and appeara nce, but is known to show a biennial bearing pattern. “Utilising tools like Cartogra pher can help growers mitigate biennial bearing and assess the success of crop regulation practice s,” Matthew Lenne explained at the field walk. The Tatura SmartFa rm hosts two experim trials with ‘ANP-01 ental 31’ pears. The Planting systems experiment encomp asses a combina tion of different tree spacings, tree architectures and rootstocks and is an ideal setup to visualise the spatial variability of flower and fruit number predicted by Cartogra pher.

PROCESSING & MARKETING
Hope beyond challenges of 2022 season AU ST RA L I A N P R EM I U M D R I ED F R U I TS It has been a very challenging harvest period for growers and processors alike. The regular rain events and unusually humid conditions created quite poor drying conditions that impacted fruit quality and delayed the season significantly. At the time of writing (mid-April), we have received less than 20 per cent of our estimated crop. Normally we would be well over 50 per cent and expect the majority of the balance within the next few weeks. The season will finish many weeks behind an average year based on the current conditions. We have had a full staff ready for harvest to gear up in early March as usual, so it has been difficult to manage the very late season. Customers are also anxiously awaiting early season deliveries. The Thompson crop is now smaller than the Sunmuscat volume, which is a big plus in a year like this of wet and humid weather. The Thompson quality has been very poor. The lack of higher grades and light base colour means there will be virtually none of this variety exported this season. This is a strong reminder of our past problems with this variety not having any
export quality grades to keep markets supplied in years of wet weather. Thankfully we now have Sunmuscat and Sunglo, which we hope will provide some reasonable quality to meet some of the export market demand. Our industry depends heavily on the premiums offered in export markets, so having consistent supply of higher grades is paramount to continued industry success. Any Sunmuscat and Sunglo that was cut late after the heavy rain events has still got a chance to dry with a light base colour at this stage. This will be a fantastic result for growers who will get a better return, and for the processors who desperately need some higher quality fruit to supply export demand. We are seeing the best results (once again) with growers who are well planned and able to manage risks of wet weather with good farming practices and timely attention to each stage of the harvesting process. It is the challenging drying years that usually see growers with good risk management strategies obtain the best overall results. It has been difficult to get contract services at the right time due to high demand in a short period of time, so
having your own equipment can be a big advantage in a poor weather year. Ashley Johnstone and Warren Lloyd were highlighted in an August 2020 Vine article discussing their collaborative approach to sharing equipment costs. This collaborative approach could be a strong consideration for small growers who cannot justify owning one of every machine required for dried grape growing. Sharing larger and more efficient wetting machines, cutter carts, sprayers, tractors, harvesters, etc. can be a great idea to ensure you have capacity to respond in a short period of time to your vineyards demands. Go back to that edition of the Vine to read about this success story. Hopefully growers have completed their harvest at the time of reading this article, with many (I’m sure) licking their wounds from a very tough season. At least we see the temporary water market being favourable for the short term, with all the wet weather taking place in catchment areas, so we hope there is still optimism around for the Australian industry within the growing district. We still feel very positive about the future of dried grapes in Australia and look optimistically ahead for a better drying season in 2023. v Enquiries: Grower liaison officer Larry Dichiera, larry@apdf.com.au 0488 199 221 Pictured: Water flowing through APDF’s Wargan vineyard after rain on 1 March 2022.

Rain detrimental to 2022 crops S U N BE A M F O O D S & A N G AS PA R K Dried vine fruit The rain before harvest, which slowed maturity, the rain in the early part of harvest, and the later rain all had negative consequences for the dried vine fruit crop.

Only a very small amount of “light type” fruit was delivered and the grades received are predominantly five and four-brown. Concern now is for fruit quality deterioration after the latest rain for unharvested fruit. The positive is that crop yields are generally up from 2021 and exceeding grower expectations. The new sultana types have again performed well under difficult circumstances and year on year there is less reliance on the traditional sultana variety. For the 2022/23 growing season, a digital spray diary will be released for all our growers to access. The Dried Fruits Australia project has delivered a great vineyard tool that will allow growers to have the most up-to-date chemical information and efficient record-keeping platform that will greatly assist in their vineyard management. Our field officers will be assisting growers with the transition from the paper-based system to the new format.
Prunes Harvest and fruit drying concluded in late March and everyone was glad to get through what has been a challenging growing, harvesting and drying season. Rainfall on the approach of harvest and then again part way through (up to 100mm) really put pressure on growers’ ability to harvest fruit and even get access to their properties to get fruit off. The
large crop required extended periods of drying as contract dryers were at capacity. The later fruit to harvest showed signs of deterioration from the wet conditions and some fruit was left on trees as it was sub-standard. The resulting dried product will have a smaller size profile than the 2021 crop and it is anticipated that only around 50 per cent of graded prunes will be in the pittable size range. Sales into the retail market continue to be elevated as there is limited access to imported Chilean and USA fruit. On the back of a successful export marketing program in 2021, there are strong enquiries for the smaller sizes again this season. The challenge is to lift the profile of Australian prunes to extract premium prices above the abundance of other product in the market to make it a viable market

Dried tree fruit The project to replant our Pike River Apricot Orchard with the new varieties of apricots is moving along. We have invited local contractors to tender for the replant, including the clearing of old trees, earthworks, irrigation and tree establishment. Stage one is the planting of 23 hectares of six of the newly developed SARDI varieties that have been selected for their maturity dates, size, shape and favourable dry ratios. Stage two will be a 17-hectare replant to complete the 40-hectare block. Our orchard manager Kevin Maynard will retire in the middle of this year. Kevin has been an integral part of transforming the orchard into a productive and viable property that has instilled the confidence in the business that we can not only compete with the imported product but also produce a premium dried apricot. We sincerely thank Kevin for the expertise he brought to the

PROFILE
Profile: James Moriarty Australia currently has a domestic supply and demand imbalance, whereby we produce approximately 40–50 per cent of our annual consumption, which means that more than one in every two dried grapes consumed in Australia is produced overseas. This is despite the fact that Australia produces the bestquality dried grapes in the world! So, if we can attract further investment into the industry to grow our supply, then we should be able to close that supply and demand imbalance and still have available supply for export opportunities. The key to attracting further investment is to have attractive returns, which are mainly driven by efficient farming techniques that drive commercial yields and strong pricing from the processors that stack up against the macroeconomic environment.
James Moriarty is the newest and youngest member of the Dried Fruits Australia board, representing corporate dried grape producer Duxton Dried Fruits. Seeing an investment opportunity in dried grapes, the company – part of Adelaide-based Duxton Capital – acquired a 200-hectare property in Liparoo in 2015/16 and began developing another larger 600-hectare property in Euston in 2017. James began working for Duxton in 2019 and shares its enthusiasm about the future of the dried grape industry. Tell us about your role at Duxton and what led you there? I’m a portfolio manager at Duxton Capital and my role is in the investments team, where I work across several of the portfolio companies – including Duxton Dried Fruits – and act as a conduit between our investors, the board, operations

teams and other key stakeholders. The opportunity to work at Duxton attracted me because of the firm’s dynamic culture, investment philosophy and strong moral compass. I was drawn to the chance to apply my skillset within the agricultural industry and help promote Australia’s world-class produce to the world. What do you enjoy most about your roles at Duxton and DFA? The chance to work alongside a group of other growers and industry operators with the same primary common goal – to grow the economic value of Australia’s dried fruits industry. What opportunities do you see for the dried grape industry? The opportunities and potential growth within the dried grape industry excite me enormously. In recent years, the industry has done a good job at arresting the exodus of local growers and supply and is now able to demonstrate that the industry is a viable and vibrant one into the future.
Can you tell us about anything new or innovative Duxton is doing? While our total plantings and presence in the dried fruits industry continues to grow, I think the most exciting area that Duxton is active in is the sustainability space. As a large landholder and producer across several different agricultural commodities, we see the huge potential that the sector has to make a tangible difference to the health of the planet and our environment. We’re pursuing a carbon-negative agenda, assessing the potential to not only reduce our footprint but also remove carbon from the atmosphere by changing our farming practices and regenerating non-productive acreage. Sustainability is a space that is receiving a lot of attention from our staff, our investors and the end consumer, so actively becoming an industry-leader and doing right by the environment aligns perfectly with Duxton’s philosophy.v
COMMUNITY
Notice board Dried Fruits Australia held its 2022 Grower Forum on 28 April at Willow & Ivie in Nichols Point, giving growers an opportunity to hear from a great lineup of speakers and connect towards the end of harvest.
Hybrid table grape growing events took place in Mundubbera and Emerald last month, to allow speakers and attendees to join if they couldn’t attend in person. Queensland growers received updates on ATGA projects as well as presentations on new technologies, new agrichemicals, Queensland fruit fly trapping and grapevine trunk diseases.
