MacAlert - January 2022

2022 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Spotting bugs. Although shells have hardened, damage is still possible and will be worse after rain. • Leptocoris. More Leptocoris have been found in orchards over the last few weeks. • Macadamia nut borer. MacTrix wasp releases should continue into January if you are in NSW or Sth East QLD • Husk spot and husk rot. January is a good time to assess the extent of loss. • The wet season has arrived. Have a plan in place to deal with storm damage to the orchard and infrastructure. • Start preparing for pre-harvest clean-up. Orchard floor fanatics make more money. • Ausmac2022 is just around the corner, register now.

MacAlert - November 2022

2022 | Australian Macadamia Society | Manual/guide

• With the current conditions, monitoring for spotting bug will be critical. Look for damage at least weekly and later you will need to drop sheet to understand blind damage. • Monitor for macadamia nut borer (MNB) eggs signalling the start of flights into the orchards, to help time releases of MacTrix. • Check shed nuts on the ground for macadamia seed weevil (MSW) eggs or larvae. • Leaf miner will likely be driving you crazy! We have had a season like no other for this usually minor pest. • With later flowering and very wet season, a later than usual husk spot control program may be required. • Nutritional demand is increasing to support both a new flush and developing nuts. • Orchards don’t need to look like golf courses! There are huge benefits to letting the orchard go. • The potential for damage from hail, wind, excessive rain or flooding from intense storms is increasing and will remain through summer, so be prepared. • The new ‘Macadamia Industry Benchmarking & Sustainability Insights 2022-2027’ project has started and data collection for the 2022 season is underway, but they need you to complete the collection form.

Industry benchmarking report 2009 - 2021

2022 | QDAF | Research report/Update

Yield, quality and planting information has been collected annually from macadamia farms throughout Australia since 2009. These data are provided either directly by growers or by processors on their behalf. Cost of production data has also been collected annually since 2013.

MacAlert - October 2022

2022 | Australian Macadamia Society | Manual/guide

• If your orchard has a history of husk spot and/or susceptible cultivars, you need to be ready to apply fungicide as nutlets reach match-head size. • Macadamia seed weevil (MSW). As weevils try lays their eggs between the husk and developing nut, there is a critical period to protect. • Spotting bug, early in the season look for damage on nutlets as they reach pea size. • Banana fruit caterpillar (BFC). In northern regions, monitor for BFC in leaf litter. • If you are unsure of how trees are progressing nutritionally, spring is a good time to sample leaves after flowering before the new flush. • Current demand for potassium and calcium is high from developing nutlets. • October/November are generally the last months you can apply animal manures and uncomposted material. • Keep up monitoring and sprayer maintenance over the next few months. • The forecasted wet period ahead is an opportunity to seed/plant areas of your farm that need improved groundcover.

MacAlert - September 2022

2022 | Australian Macadamia Society | Manual/guide

Key topics this month include: • Monitor weekly to fortnightly for pest and diseases that affect flowers. • Best practice during flowering is to bring managed pollinators into the orchard to assist naturally occurring pollinators and hives that remain year-round. • During spring, biological processes and input demands will increase. • All preparations for spraying should now be complete and your equipment calibrated and ready to go. • You are likely to be doing some sort of canopy management over the next few months. Remember to be safe.

Husk spot control and managing fungicide resistance

2022 | Akinsanmi F | Research report/Update

With a number of fungicides registered for controlling husk spot, including new products containing co-formulations of two chemical groups, this article emphasises the importance of implementing strategies to avoid chemical resistance. The article outlines practices to avoid resistance, including monitoring, attention to recommended ways of using different fungicides and integrated pest management.

Growers guide: Supporting Stingless Bees for pollination of macadamia

2022 | Wilson R, Wallace H | Manual/guide

Stingless bees are excellent pollinators of macadamia and will forage heavily on macadamia when it is in flower. However stingless bee hives that are left on-farm year round may starve if they do not have access to other food sources when macadamia is not flowering. This guide identifies pollen food sources for stingless bees year-round. We identified major plant sources in the pollen pots of 57 Tetragonula carbonaria colonies over 2 years in orchards and forests in southeast Queensland.

Macadamia Weather Network

2022 | Australian Macadamia Society | Manual/guide

The Macadamia Weather Network has been developed to provide AMS grower members, industry stakeholders and researchers with real-time weather station data from across multiple macadamia growing regions in Australia.

MacAlert - August 2022

2022 | Australian Macadamia Society | Manual/guide

Key Topics this month include: • Start monitoring for pest and diseases that impact flowers. • If you haven’t already done so, book a pest consultant to regularly monitor your orchard. • As weather warms tree nutrition and water requirements will increase, particularly as flowers have started to emerge so early in the season. • At the end of harvest season, which for many is still far away, conduct a thorough audit of what needs to be repaired. • Once you have finished harvesting review your season with your consultant/GLO and decide on post harvest orchard floor repair and canopy management. • Prepare for the start of a new crop protection season. • Have an agreement with your beekeeper if you’re bringing managed pollinators into the orchard.
