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.

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 - 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.

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.

Marketing Update (July 2022 MacGroup)

2022 | Price J | Presentation

The global tree nut industry is facing rapidly growing supply, shipping delays and increased freight costs which is leading to increased price pressure. However, there remain many opportunities to promote consumption and drive growth to rebalance supply and demand, including focussing on innovation and new market development. Macadamias account for less than 2 per cent of the world tree nut market, providing both challenges and unique opportunities. The macadamia industry is well placed to meet consumers increasing desires for healthy whole foods, and the Australian marketing program is focussed on inspiring consumers, educating trade customers, and influencing food manufacturers to experience Australian grown macadamias.

Building a better AMS (July 2022 MacGroup)

2022 | Burnett J | Presentation

At the July 2022 MacGroups, AMS CEO Jolyon Burnett presented the findings of an independent survey regarding proposed changes to the AMS membership structure, resourcing and additional training and development opportunities. The survey was conducted by Survey Matters, distributed to 708 members between 23 May and 17 June 2022, and received a total of 268 responses.

The A-Z of Macadamia Flowering (July 2022 MacGroup)

2022 | Kojetin L | Presentation

At the July 2022 MacGroups, Industry Development Manager Leoni Kojetin presented information on how to maximise flowering and convert it into high quality nuts. This includes understanding the stages of flowering and factors that influence flower initiation, growth and development into nuts, as well as key inputs required for healthy flowers and nut set.

Disease risk assessment guide for macadamia flower blights

2022 | Akinsanmi F | Manual/guide

Flower blights refer to a number of pathogens which can cause significant damage to macadamia flowering. To assist with monitoring and management it is essential to understand the different blights and the conditions in which they are present. As part of the Integrated Disease Management Program for Macadamia, led by the University of Queensland, a risk assessment tool has been developed. This includes visual signs, flower stage susceptibility and importantly temperature and humidity ranges in which each disease proliferates.
