Next steps to eradication FF meetings TOMORROW!
The ‘next steps’ in eradicating fruit fly will be the focus of two meetings to be held by Primary Industries and Resources SA (PIRSA) tomorrow, September 3. Up for discussion will be the benefits and implications of removing Riverland west from the Fruit Fly Exclusion Zone. The meetings will be held at Renmark at 1pm in the Nanya Bistro, Renmark Hotel and the at 4pm at the Waikerie Hotel.
Here’s what PIRSA plans to cover:
Eradication of fruit fly outbreaks in the Riverland is progressing in the Waikerie, Cadell (+ Cadell B), Holder, Sunlands and Taylorville areas.
Together, this group of fruit fly outbreak areas is referred to in the fruit fly response program as Zone 2 (Zone 1 was the former Swan Reach outbreak area).
PIRSA is facilitating this industry-led initiative and will look to begin transitioning activities in Zone 2 towards a release from outbreak, in line with the Australian National Fruit Fly Management Protocols.
Consistently low fruit fly detections in Zone 2 over the past 12 months mean the next steps along the path to eradication and area freedom can be taken.
Next steps are being planned in three stages to manage a transition from low detections to no detections, a release from outbreak for Zone 2, and eventually reinstatement of Pest Free Area status.
This is an important step towards supporting the economic and social recovery of the Riverland horticulture industry and community, while maintaining confidence in South Australia’s biosecurity system.
PIRSA will continue to work closely with industry to support Zone 2 growers during each stage, because we all want to see area freedom return.
It is essential produce continues to be moved only under approved conditions. It is critical to continue protecting the Riverland, particularly Zone 2, from untreated host material that might cause further fruit fly outbreaks or detections.
It’s showtime!
Thousands of cups of freshly squeezed juice and pieces of fruit are expected to be sold and distributed by Citrus SA’s crew at the Royal Adelaide Show when it starts on Sunday. The stand in the Goyder pavilion is always a big hit with showgoers, keen to secure a taste of the Riverland. This year, Citrus SA has Citrus Australia on board to raise awareness of exotic diseases like Citrus Greening and canker. Keep an eye on our Facebook and Instagram pages for updates. There will be a full summary in next month’s e-news.
September production notes
Pruning: Annual pruning programs are likely to be well underway. Those who prune usually see a vast improvement in class one fruit pack outs, particularly if we encounter a windy spring resulting in marking in last season’s fruitlets.
Fertilising and Fertigation: Soil temperatures are starting to warm up so it’s time to start broadcasting fertiliser to cover the spring flush. Those on drip irrigation or Micro jets should also begin fertiliser programs. Foliar applications can also be applied in late August to ensure a healthy spring flush.
Irrigation: Growers should also be monitoring soil moisture with the onset of warmer weather as more irrigation output may be required.
Weed Control: Once fruit has been harvested it is important to control weeds to reduce the competition for water and nutrients, especially during the spring flush period and after recent rainfall.
Gall Wasp. This pest is on the rise and growers should talk to their agronomist for the best control option.
Earwigs. After such a wet and cool period over the last 6 months conditions are perfect for earwig numbers to increase. Be aware of your high pressure patches and treat accordingly. Good bait is available and cover sprays also work.
*Advice is of a general nature and growers should seek individual advice from their agronomist or packing shed.
