• 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.

Botryosphaeria dieback (March 2021 MacGroup)

2021 | Akinsanmi F | Presentation

If left unchecked, the disease Botryosphaeria (which is becoming more prevalent in macadamia) can kill trees. Symptoms are first seen in late Spring, becoming more evident by mid to late Summer. Susceptible cultivars are A203 and 849. Dr. Akinsanmi outlined the specific conditions/time when spores are abundant, as well as control measures.

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.
