Australian Macadamia Native Bee Pollination Quick Guide

2026 | Barton K, Cannizzaro C, Grieve E, Kojetin L, Trueman S | Fact Sheet

Native stingless bees are valuable pollinators of macadamia and complement the pollination services provided by European honey bees. Successful native bee pollination depends on healthy colonies, appropriate hive placement, suitable habitat and good communication. This guide summarises the key recommendations for pollination-ready hives and responsibilities of growers and beekeepers. For detailed guidance, refer to the Australian Macadamia Native Bee Pollination Guidelines on the AMS industry website.

Flower blights in Australia: identification and management

2026 | Kojetin L, Long E, Akinsanmi F | Fact Sheet

Herbicides are one tool in orchard floor management, not a stand-alone solution. Best results come from using them as part of an integrated program that includes groundcover management, timing, and mechanical control.

MacAlert September 2026

2026 | Yamao M, Grieve E, Kojetin L, Long E | Manual/guide

Key messages this month include:
Monitor for pests and diseases that affect flowers.
In NSW and QLD, lace bug risk has peaked. Control with selective chemistry to protect beneficial insects.
In QLD, watch out for flower caterpillar eggs.
Be aware of withholding periods when using chemicals. Read every part of the label.
Be mindful of managed and wild pollinators when planning orchard activities/ inputs.
Water demand is increasing so have moisture monitoring and retention strategies in place.
Apply a good proportion of your annual K budget in the months after flowering as nutlets have high nutrient demand.
Keep soil pH to 5.5-6.0 to maximise nutrient availability.
Seed ground cover and prepare inter row to provide organic matter, erosion control, beneficial insect habitat and soil productivity.
Be ready for husk spot and Macadamia seed weevil control when nutlets are match-head size.
Have you ordered your MacTrix wasps for macadamia nut borer control?

MacAlert August 2026

2026 | Grieve E, Kojetin L, Long E, Yamao M | Manual/guide

Key messages this month include:
Do you know what flower support and protection to prioritise at each flowering stage?
Be on the look out for lace bug and flower caterpillar.
Check for thrips, mites, aphids and felted coccid.
Diazinon is no longer permitted after August 2025 for any use.
Just because a product is registered in Australia, does not mean you can use it safely.
Do you have sufficient boron for flowering, calcium for nut set and potassium for growth?
Tree water demand is increasing, so have soil moisture monitoring in place.
Flag trees at risk of mistletoe infestation in your orchard and be aware of correct control methods.
Have you made plans for managed pollinators?
Sprayer calibration and coverage tests should be done by now.
Prepare for fire risk season.
Husk spot control starts shortly after flowering.

MacAlert July 2026

2026 | Grieve E, Kojetin L, Long E | Research report/Update

Key messages this month include:
Start thinking about crop production and protection.
Monitor for lace bug and flower diseases.
Flower blights can cause major crop loss. Closely monitor blocks with closed canopies and a history of flower blight. Cultural controls like good light and airflow help.
Before spray season begins, ensure you have the right orchard volume, sprayer setup, calibration, airflow, coverage and correct rates.
When harvesting is finished, thoroughly clean shed equipment and vehicles. Remove any residual nuts as they attract vermin and harbour pests such as kernel grub.
Conduct a chemical store audit.
Plan ahead for late winter/spring inputs. Prioritise applications that need to be completed before or during flowering.
Review irrigation capacity and water availability before demand increases.
Lime or gypsum applications need to be early as it takes time to influence the root zone. Boron should only be applied in small amounts to prevent toxicity.
Ensure pollination is part of your orchard planning.
Join us for the MacGroups this month to learn about pollination, pest/disease management, new cultivars and hear important industry updates.

MacAlert June 2026

2026 | Grieve E, Kojetin L, Long E | Research report/Update

Key messages this month include:
Peak pest and disease monitoring and control period is approaching so start the discussion with your pest consultant about the season ahead
Watch out for flower blights and the newly classified rachis tip dieback
If your region is frost prone, keep up to date with risk factors and mitigation inputs
Boron is required for flower and nut development - decide on either ground or foliar application
Have you ordered organic material to be applied after harvest? The sooner it's on the orchard floor, the great the benefit for the season ahead
Profiling is best done in drier months
Are you ready for spraying?
Ensure staff have valid chemical application certifications
Make sure to have a pollination plan
Join the July 2026 MacGroups to hear the latest industry updates on disease prediction, successful pollination, hive standards and new cultivars.

MacAlert May 2026

2026 | Grieve E, Kojetin L, Long E | Research report/Update

Key messages this month include:
Phytophthora remains a pervasive disease in macadamia. While conditions this season have been drier, the impacts of multiple wet seasons are still prevalent in many orchards.
Continue auditing harvest efficiency, checking the condition of consumable or wearing parts and looking out for machine damage to nuts.
Haloxyfop is not suitable for use in during harvest periods.
Planning crop inputs for the season ahead is crucial. Be sure to assess broader aspects such as soil fertility to support long-term productivity.
With cooling weather, the opportunity to apply ethephon may have passed. Consider the conditions required for effective results.
Begin monitoring for frost events and determine if protectants are required.
With recent rain, nut could be at a higher field moisture. Removing the heat and moisture from respiration is essential to maintaining kernel quality.
Book your pest consultant to monitor for critical pests and diseases next month.
Contact a beekeeper to bring managed hives to the orchard. Varroa mite is having severe impacts on the honey bee industry, so don't expect hives to be as easy to secure as usual.
Save the date for July MacGroups. Running from 14 to 29 July, be sure to mark your region's MacGroup in your calendar.
