Novel technologies and practices for the optimisation of pollination within protected cropping environments (ST19000)

2021 | Hort Innovation | Research report/Update

Using a multifaceted approach, this program will focus on the productivity and quality of pollination in protected cropping environments. The aim is to understand the current impediments to adequate pollination, then improve these systems through the use of advanced technology.

MacAlert - September 2021

2021 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Continue to monitor at least twice per week for pest and diseases that affect flowers. • Lace bug, flower caterpillar and flower diseases such as Botrytis and Cladosporium are more prevalent in some regions. Monitor weather conditions and known hotspots within the orchard. • Discuss control options with your pest consultant or grower liaison officer to select strategies and application timings that will have minimal impact on beneficials such as bees. • Communicate with your beekeeper on stocking rates and hive positions to develop a plan that provides flexibility for you both, and crucially, keeps bees safe. • Tree water demand is increasing with the warmer weather • Discuss tree nutritional demand and spring soil and leaf sampling with your consultant • After mulching remaining nuts to reduce the risk of rats and kernel grubs, consider reduced mowing strategies to allow grass and other inter-row species to flower.

Benefits of double ground wood chip (August 2021 MacGroup)

2021 | Australian Macadamia Society | Video

Alloway Macadamias farm manager Johan Oosthuizen and Macadamias Australia Grower Liasion Rohan Orford show how horizontal grinding is assisting to produce a high quality double ground wood mulch from trees being removed in high density orchards. The horizontal grinding process helps to control mulch particle size and the resultant wood strands form a much better orchard floor surface and root growing environment than traditional wood chip from a tub grinder.

Cross pollination for macadamias (August 2021 MacGroups)

2021 | Australian Macadamia Society | Video

The first of our series of online MacGroup videos is out now! Professor Stephen Trueman (Griffith University) poses the question: how important is cross-pollination for macadamia? Stephen shares results and insights from recent macadamia orchard research.

Innovative mulcher developed by macadamia grower Lance Emery

2021 | Australian Macadamia Society | Video

Lance runs Mill Farm in Nashua in the NSW Northern Rivers region with his wife, Ina. The farm’s productive acres are on very steep country, and over the years Lance has worked hard maximising ground cover and minimising erosion. Watch now to learn about the new machine developed by Lance, protecting ground cover and controlling pest.

MacAlert - August 2021

2021 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Start monitoring for pest and diseases that impact flowers, paying particular attention to out-of-season flower problems that can build up and a wet August forecast. • Active environmental and visual monitoring for pests such as lace bug and flower caterpillar and diseases such as flower blight start. • As the weather warms tree nutrition and water requirements increase, particularly once flowers emerge. • At the end of harvest, review the season including: o Machinery/equipment performance and required upgrades o Processor consignment reports o Crop loss assessments and yield monitoring o Orchard health assessment • Prepare for the start of new crop protection season. • Now is the time to think about seeding a cover crop. • Pollination is round the corner and managed hives need to be arranged.


2021 | Australian Macadamia Society, Trueman S, Wallace H | Fact Sheet

Pollination by agents such as insects underpins production in many crops, including macadamias. Ensuring efficient and effective pollination is one way that growers can increase nut yield in orchards.

Environmental effects on flower blight pathogens

2021 | Akinsanmi F, Prassannath K, Galea VJ | Article

Flower blights (grey mould, green mould and dry flower) are important diseases of macadamia. Lack of information on pathogen biology and disease epidemiology in macadamia has hampered control options. Effects of climatic variables including temperature, relative humidity (RH) and vapour pressure deficit (VPD) on the abundance, germination and growth of conidia of four fungal pathogens that cause various flower blights in macadamia were studied.
