AmberMacs Macadamia Expo 2024
Get ready for AmberMacs Expo 2024
In February 2024, Mbombela will host the third AmberMacs Macadamia Expo – an event set to be the biggest of its kind, featuring over 180 exhibitors and a number of excellent guest speakers who will be hosting a series of seminars and presentations on macadamia farming and the industry in general.
According to managing director of AmberMacs, Philip Moufarrige, the expo will once again offer something useful for both seasoned and newer farmers alike.
“The 2024 expo aims to benefit and support growers and suppliers through the sharing of the latest ideas and innovations in farming practices, technology, pest control, irrigation, dam building, pruning, harvesting and drying, and we hope you will attend the varied presentations on offer by the industry’s foremost experts.”
Held over two days, from February 8 to 9, visitors will have the opportunity to learn about the history of macadamia farming, the challenges faced by the industry and the potential for growth in the global market.
Visitors will also be treated to a variety of macadamia-based delicacies, such as macadamia ice cream, macadamia cookies and macadamia coffee, and will be among the first to savour the unrivaled creaminess and flavour of Giraf.
Giraf is an authentic macadamia drink: A dairy-free, sustainably sourced, creamy delight that is delicious on its own or in a smoothie, goes well with your cereal and froths beautifully in your cappuccino.
One of the highlights of the expo will be the keynote speech by nationally renowned economist Dawie Roodt, who will share his 30 years of expertise in economics.
Roodt, the founder, director and chief economist of the Efficient Group, serves on a variety of investment committees within it. His latest role is that of chairperson of Efficient Private Clients, of which the Efficient Group is the majority shareholder.
He specialises in monetary and fiscal policies, and is currently doing extensive research on the possible impact of cryptocurrencies on monetary policy.
He is closely involved with the management of client asset portfolios. His interest in international and local politics has grown and he has become knowledgeable in these fields as well.
Roodt is ranked one of the most referenced economists in the country and received the prestigious Economist of the Year Award from Media 24.
He has been the anchor presenter of the television programme Ontbytsake for the past 19 years.
The AmberMacs Macadamia Expo is a great opportunity for the exhibitors to showcase their products and for the visitors to learn more about the macadamia industry.
It promises to be an exciting event that will leave the visitors with a sense of anticipation and excitement for the future of macadamia farming.
According to Moufarrige, organiser Andri van den Bergh has worked around the clock to bring together an even more extensive and varied range of exhibitors, offering products and services to the macadamia industry with a view to streamlining the interactions between growers and suppliers.

Felted coccid an enemy of mac trees
Dr Schalk Schoeman
The macadamia felted coccid was first recovered from infested trees in the Barberton Valley during 2017.
It soon became apparent that this seemingly innocuous insect was a game changer, and it affected the trees in the following ways:
- Because it was introduced without its natural enemies, population increases were rapid, leading to scale encrustations of main branches, stems twigs, nuts and leaves.
- This placed considerable stress on the trees leading to leaf necrosis of the inner portions of the trees, quickly followed by dieback of large sectors of the trees.
- The ensuing physiological stress also led to manifestation of secondary problems, such as Botryosphaeria dieback and/or bark and ambrosia beetle infestations, leading to a vicious downward spiral.
- Trees may recover from this, but yields of initially infested trees take very long to return to preinfestation levels leading to compounded financial losses.
Unfortunately, no pesticide is registered for this pest, but the process of emergency registration is well on its way and a range of products should be registered under Act 36 before the end of the year.
Although no products are currently legally registered, the following strategic options are available:
- Soil-applied systemic products. These products are taken up by the roots and are transported in the vascular tissue (xylem) of the trees. As such, they will not be effective on non-feeding stages, but will have an effect on actively feeding females.
- Lipid biosynthesis inhibitors (Irac class 23). Sprayed on the foliage and may be basipetally transported in the phloem tissue.
- Juvenile hormone mimics (Irac class 7) and chitin synthesis inhibitors (Irac class 16). These products will only work against crawlers, and frequent usage may lead to secondary pest infestations.
- Smothering agents (mineral oil). Mineral oil is a very IPM-friendly way of controlling scale insects, but should not be sprayed on trees experiencing stress, and never on flowers.
- Contact insecticides. Some broad-spectrum contact insecticides will still give good control of scale insects, but should be used in combination with mineral oil.
Pruning to ensure optimal spray mixture penetration up to the main stem is important if effective control is to be expected.
Post-spray scouting with inverted duct tape is also very important, as it will determine if a follow-up spray is needed, and if so, how soon after the initial spray will it be required.
Managing spray drift in macadamias
Dr Schalk Schoeman
Spray drift is the unintentional airborne movement of pesticide dust (or droplets) during or soon after application, to any site other than the intended area.
It is estimated that as much as 3% of pesticides in the USA are lost every year due to drift.
Why is drift a concern?
- Less product deposited on the target.
- Financial losses associated with drift.
- Risks of environmental contamination, injury or loss of reputation.
The following can be done to minimise the impact of spray drift:
- Continuously monitor meteorological conditions and adapt sprayer configurations if significant changes occur.
- Do not spray if the relative humidity is lower than 40% or when the temperature is higher than 25°C.
- Increase droplet sizes by reducing spraying pressures. Increases of carrier volumes and nozzle selection should be considered. Higher flow rates with optimal nozzle selection should lead to bigger droplets.
- Use commercially available drift retardants.
- Travel speed of the spraying rig will have a big effect on spray deposition and concomitant spray drift.
- Establish buffer zones between orchards and sensitive areas.
- Maintain good relations with neighbours.
- In-air assisted sprayers. The aim is to replace the inside volume of the tree canopy with pesticide-laden droplets. The ideal is not to spray through the tree canopy, as excessive air volumes can force the leaves together, leading to poor coverage and excessive drift. Reducing excessive air volumes will also lead to a considerable saving in fuel and wear and tear on equipment.
- When spraying the last row in a block, turn off the nozzles facing away from the trees. The costs and environmental implications of this practice are obvious.
- Where trees are still young and especially where there are still considerable gaps between the trees, substantial savings can be made by equipping the spray rigs with sensors that switch the nozzles off when
the rig is passing the gap between two adjacent trees.

Lowveld Macs off to a flying start
In February last year, Jaco van Eeden of Eden Farm in White River started the construction of a macadamia roasting plant, adhering strictly to food grade stipulations.
Four months later, and contrary to the naysayers, they roasted their first batch. Van Eeden attests that the feedback has been exceptional.
“Our new enterprise, Lowveld Macs, is experiencing rapid growth, with international distribution also in our sights.
“On the farm, we harvest, dehusk, dry, sort and supply AmberMacs with our harvest before receiving the kernels back. These are then roasted, caramelised, cooled, flavoured, packaged and distributed. Hence, on the farm, we add value to the product before sending it directly to market.”

Shot-hole borer now in the Lowveld
Dr Schalk Schoeman
During 2015, researchers involved in subtropical crops attended the World Avocado Congress in Lima, Peru.
A series of talks by American researchers on a new but devastating stem-boring pest of avocados drew everyone’s attention.
First records of bark beetles on macadamias in South Africa were actually recorded a year earlier, during 2014, in Barberton and White River. These beetles were not identified, but infested trees were removed and destroyed, and surrounding trees were treated with insecticides as a precautionary measure.
This appeared to be effective, as no subsequent infestations were reported.
During 2017, the dreaded polyphagous shot-hole borer (pshb) was recorded in London plane trees in the Durban Botanical Garden.
Since then, this tiny beetle spread rapidly to Gauteng, KZN, Eastern Cape and now Mpumalanga as well.
Macadamia SA is busy with surveys in Mpumalanga and KZN, and so far, an extensive complex of bark- and stem-boring insects (including pshb) were recovered, consisting of many species.
Similar surveys conducted on other subtropical crops as well as on stone and pome fruit trees in the Western Cape yielded similar findings.
This is not only limited to South Africa, but appears to be a global issue at the moment, as many fruit-producing countries reported similar findings.
As one can imagine, this situation is changing rapidly, and the ecological consequences for individual fruit industries is currently poorly understood.
The effect on some ornamental trees, however, can be disastrous, and have been highlighted by many recent press reports.
Not all beetles are a death sentence to infected trees
- Worldwide it is estimated that approximately 6 000 species of these tiny beetles occur. Only a very small percentage of them are pests and the majority fulfil a very important niche. They are regarded as nature’s undertakers and recyclers, and will affect mostly moribund or dead trees.
- Not all trees are susceptible to the ravages of these insects. Some, like macadamias, appear to be less severely affected, but remember that nature is dynamic and there is a constant war for supremacy between insects and host plants. The balance of power (either side) can shift remarkably quickly – so no guarantees here.
Why are these insects such severe pests?
- Very few insects can digest lignin and cellulose. To get around this conundrum, some of these beetles can infect a host tree with a fungus that firstly blocks the vascular tissue and secondarily breaks down these otherwise indigestible tissues. In the process, they often transmit severe plant diseases that can kill trees very quickly. Examples here are Dutch elm disease, as well as a disease submitted by the southern as well as mountain pine beetles in Canada.
- These beetles make tiny holes in the wood and spend most of their lifetimes in their tunnels. No pesticide has been registered for this pest, because it is nearly impossible getting chemicals into these holes.
Symptoms of bark beetle infestation
Infested trees appear symptomless for quite some time, but eventually, feeding and tunnelling of the beetles result in characteristic expelled sawdust through the small entrance holes (±1mm). Some sawdust particles tend to adhere to each other and form matchstick-like projections sticking out from the various entrance
holes. Sawdust also accumulates
around the bases and in main crotches of affected trees.
What can and should be done to limit the effect of these beetles in my garden and/or orchard?
- It is confirmed, the pshb is in the Lowveld, and being aware of a problem is the first step in managing it.
- The second step is to inspect the trees in your garden and to be aware of the symptoms (sawdust around the bases of the trees as well as general tree decline).
- Call an expert to verify. These beetles are tiny, and superficially, many species look alike. It may therefore be necessary to send it away for molecular identification.
- Destroy infected trees as well as dead wood. Be aware that holes in dead wood are most often caused by either indigenous or naturalised species.
- Do not move dead wood between different geographical areas. Under no circumstances should dead wood be taken into the Kruger National Park for a nice evening bonfire.
- These insects prefer to live in moribund trees, therefore, maintaining optimal tree health is most often a very effective first line of defence.
- If the pest is noticed in your garden, it is good practice to notify your neighbours as well as the parks section of your local
city council.
