After every Citrus SA committee meeting, Chair Mark Doecke provides a comprehensive update on the committee's recent activities. In the latest update:
Harvest Highlights: Mark reports the navel season has concluded and Valencia harvest is well underway. Growers are reporting a slight kick in prices for Valencia oranges. Fruit Fly Update: The ongoing battle against fruit flies remains a priority. Mark highlights that the number of detections is notably low, thanks in part to the release of sterile fruit flies by PIRSA. The introduction of up to 40 million steriles per week is proving to be a highly effective strategy. Industry Representation in Canberra: Mark shares his participation in a Taste the Basin event, where he engaged with politicians in Canberra to showcase the citrus industry. -
Citrus SA held its annual general meeting and grower information day on Friday, October 13 at the Barmera Events Centre.
If you missed it – stay tuned because in this episode of The Citrus Segment – we’ll give you a snapshot of the day as I catch up with some of the guest speakers.
The day kicked off with the AGM – Citrus SA chair Mark Doecke shared what the committee has been working on over the past 12 months and where SA citrus grower’s levies have been directed.
Noel McPherson a citrus and wine grape grower, Waikerie. Noel travelled to the US earlier this year to look at the impact of HoungLongBing or Citrus Greening has had on the industry in Florida.
Theunis Smit, General Manager, Carbon Friendly, covered how citrus growers could benefit from carbon farming .
There’s a new device to help measure water use in the orchard and it uses infra-red technology Jay Holata, chief executive of Athena IR Tech gave some background on the company and its product.
The fight against fruit fly continues in South Australia. Summerfruit SA executive manager Tim Grieger says SA is winning the fight against the pest. -
Mike Arnold has been a fruit grower at Waikerie for more than seven decades and he’s been instrumental in the development of the citrus industry nationally, particularly in the areas of propagation and variety improvement.
Some of his roles over the years have included:
Chairman of Auscitrus after the merging of the Australian Propagation and the Australian Citrus Improvement Associations in 2001 and chair of the Australian Citrus Improvement Society of which he was a founding member.
He’s also a stalwart of his local community in Waikerie, recently recognised by the South Australian Country Fire Service for his 62 years of volunteering.
His sons have followed in his footprints both with the CFS and horticultural industries, just as he did when he returned to the family farm almost seventy years ago.
Steve Burdette says Mike has always had a great interest in plant health, variety development and rootstocks.
“He’s always been an example of how people unselfishly donate their time in not just the best interests of the industry but the growers as well.
“I think a lot of people totally underestimate what Mike has contributed.”
Gary Eyles, from Eyles Citrus says Mike has been instrumental in the success of Auscitrus.
“He’s been very passionate about Auscitrus and about having the buds and seeds that Auscitrus produce being clean and being the basis of a nice clean industry here in Australia,” he said.
He’s also well renowned for his love of a very particular desert.
“If you ever go for dinner with Mike, he invariably asks for icecream and sprinkles, Gary said.
“It’s quite a joke, especially around the Auscitrus board table….to the point where I’ve seen some of the board members bring along some sprinkles, just for Mike.”

In recent years orange juice has received some negative press due to its perceived high sugar content.
But researchers at Nutrition Research Australia have been able to provide data from a study, which shows there’s a need to look at the whole product and the benefits it can provide.
Tim Casserati is the director of translational science at Nutrition Research Australia and says while vitamin C might be the obvious and most well-known health benefit from 100 per cent orange juice – it also contains many micronutrients and anti-inflammatory properties.
“When we look at the data for 100 per cent juices – all juices, what we find is there is actually more benefit than there is harm,” he said.
“The strongest evidence is that there’s benefits for heart health and anti-inflammatory effects.
“Some of the benefits for heart health was a reduction in blood pressure and also a reduction in inflammatory markers.
“When we think about juice we automatically think, high sugar, low fibre but when we actually dive into what’s in juice, it’s an incredibly complex mixture of a range of different plant chemicals.
“We know that it has good micronutrients profiles so that’s comparable to whole fruit so that’s things like vitamin C, folate, potassium – we know that these micronutrients can support health.
“Vitamin C has many effects in the body, it can support immunity, while potassium can help lower blood pressure so these micronutrients are high in juice and can play a role in health.”
Mr Casserrati says juice also contains bioactive compounds, particularly polyphenol.
‘These are compounds found in plant foods like fruits and vegetables that give them their flavour and colour and they’re often known as antioxidants, but they have a lot more function in the body than antioxidants,” he said.
“They can have pre-biotic affects which means they can feed the good bugs in our guts, they also can have heart protective properties, anti-diabetic properties or support our brain health.
“Interestingly, 100 percent orange juice is one of the richest sources of these polyphenols in our diet.”

It will come as no surprise to growers that albedo breakdown is quite widespread this season across the three major growing areas.
At a Citrus SA seminar late last month, former citrus researcher Michael Treeby said it was improbable that every grower in the Riverina, Sunraysia and the Riverland forgot to apply preventative treatments this season.
So, what is causing it?
“The effect of season appears to us, from our data - from our limited data - to be greater than the degree of control we can deliver by calcium or gibberellic acid (GA),” he said.

In this episode of The Citrus Segment we talk to Steven Falivene from the New South Wales Department of Primary Industries about frost mitigation strategies and weather forecasting services. Is it worth paying extra?

In recent years, Citrus SA has been working with Primary Industries and Region’s SA to identify and address the increased risk of fruit fly becoming established in the Riverland.
Earlier this year, new regulations were introduced into the SA Plant Quarantine Standard to require that fruit bins coming from interstate be checked and certified as clean. Under SA’s strict biosecurity measures, this also means that the bins need to be checked on arrival and cleared.
This episode looks at the new regulations with PIRSA’s manager of Plant Health Operations Nick Secombe. -
Knowing what is the next up and coming citrus variety which tastes good, looks great and most importantly will be well received by markets is always difficult to gauge.
The New South Wales Department of Primary Industries at Dareton has a range of citrus trials underway to demonstrate new varieties to growers so they can make educated decisions.
Each June, Citrus SA hosts a trip across the border to take a look at the varieties being investigated. In 2020, the Covid-19 pandemic put a stop to growers physically visiting the orchard, but research horticulturalist Dave Monks was able to provide a ‘virtual tour’ for South Australian growers.
Citrus SA has provided the audio from this presentation for your consideration.
