MacAlert - July 2021

2021 | Australian Macadamia Society | Manual/guide

• Monitoring is essential for any pest and disease management and your consultant should be making regular visits by now. This is especially important if you have out of season flowering, which can be a breeding ground and springboard for pests and diseases during the main flowering. • If you haven’t ordered your organic inputs for the application post-harvest, this may be your last chance. In most cases, particularly if you have sparse to moderate ground cover, highly refined and expensive composts aren’t necessarily better. • Ensure adequate boron levels for flowering. In dry conditions, you’ve likely missed the window for ground application. • If you are reliant on farm dams, determine your water on hand for the coming season. Don’t forget to take into account losses to evaporation. • If you have finished harvest or even just in some blocks, then canopy management should be under way. The more light you are able to intercept and distribute evenly through the canopy, the better result you will have in every area of production! • Professional beekeepers are looking to place beehives on orchards. They will need good access, a level site for the hives, available water and most importantly, your assurance that you will communicate with them to keep bees safe. Your local apiarist association can help you connect with beekeepers. • Post-harvest is an incredibly busy time. You’re still finishing the season while preparing for the next and probably the one after. The best orchard managers have a post-harvest schedule that clearly prioritises orchard operations.

• Monitoring for pest and diseases is a priority for the rest of the year to guarantee next year’s crop. Check now for lace bug, particularly if your orchard has a closed canopy. • You can still change your nutrition program if you get in quickly. Discuss your soil and leaf sampling results with your consultant to develop a plan that considers crop load and weather events. Check that you applying enough boron, at the correct rates, to support flowering. Remember to order organic material to be applied after harvest. • Consider tree shaking to reduce the number of late harvest rounds and clean up trees, especially if you have cultivars dropping nuts or sticktight varieties. • Make sure you are prepared for the next three months when you will busy with harvest and post-harvest activities by developing a plan to help you with timing and logistics. Check your nut storage to ensure there is constant air flow through nut beds and that you don’t have sites in your silos that are uninsulated and heating nuts. • Start to get ready for crop protection spraying by cleaning, servicing and calibrating your equipment. Make sure your certification and required licences are all up to date. • Develop your plan for orchard floor and canopy management and book your contractors so you don’t miss out.

MacAlert - March 2021

2021 | Australian Macadamia Society | Manual/guide

· Prolonged wet weather can increase the incidence of Phytophthora root rot and tree canker. If you notice symptoms, get professional advice and implement a Phytophthora management plan. · Macadamia nut borer activity has increased and, while it is too late to prevent losses this season, review your management programs with your consultant ready for next season. Continue monitoring for late season spotting bug and check silos for pests such as kernel grub. Audit rat damage and bait hotpots. · Monitor your nutrition program and, with water demand still high in March, schedule irrigations as needed. · Check and maintain orchard machinery, harvesters and infrastructure ready for harvest. Make sure silos are clean, that fans are working and will provide ventilation and that you have a relative humidity and temperate controller installed. · Sample nuts to assess potential crop loss percentage and reasons for this.

MacAlert - February 2021

2021 | Australian Macadamia Society | Manual/guide

· Look out for husk spot damage, which causes premature nut drop and loss of up to a third of the crop. Check for signs of fruit spotting bug and vertebrate pests such as rats and pigs. Develop your control strategies with your pest consultant and make sure your spray equipment is calibrated before applying any chemistry. · Get ready for orchard clean-up and harvesting by ensuring equipment such as mulchers, harvesters, dehuskers and mowers are checked for signs or wear and maintained ready to go. · As the season starts to cool, review your irrigation schedules and nutrition program. · Have your plans in place for harvest and to ensure prompt delivery of nuts to your processor.

MacAlert - May 2021

2021 | Australian Macadamia Society | Manual/guide

· This is an important month as it is the time to be thinking ahead to ensure you are ready for next season. · With the wet season almost over, check your orchard for tree health and any drainage or groundwater seepage issues, which can contribute to the incidence of Phytophthora and yield issues. · Check your leaf sample results against Australian standards to confirm details of your nutrition program. Plan ahead and order compost and organic matter amendments so you can apply them straight after harvest. · Continue your regular equipment maintenance program, including machinery to be used for post-harvest tasks such as for canopy and orchard floor management. · Check your consignment reports, block by block, to identify any issues affecting yield so you can implement plans for next season.

MacAlert - April 2021

2021 | Australian Macadamia Society | Manual/guide

· Manage vertebrate pests such as rats, pigs and cockatoos, which can cause significant damage during peak nut drop. · It’s time to sample leaves and soil so you can determine a nutrient budget and implement your nutrition program post-harvest. Water use by trees is decreasing so less irrigation water may be needed. It is not recommended to use ethephon, which is useful for cleaning up trees, reducing pest and disease carryover and canopy management, after this month. Make sure your shed can handle the extra nut volume if you use ethephon. · Schedule weekly preventative maintenance on all harvesting and shed equipment so you are not delayed by machinery breakdowns. Check whether you need to invest in new fingerwheels. · Check your harvest efficiency by auditing blocks for nuts left behind.

Integrated Orchard Nutrition (ION)

2017 | Australian Macadamia Society | Fact Sheet

Integrated orchard nutrition (ION) works together with integrated orchard management (IOM) to maximise profits and production for macadamia orchards. It is important to establish an effective IOM program before considering how an ION program could assist in further improving and maximising results.
