Summary

This 11th edition of the NSW Macadamia plant protection guide aims to provide commercial macadamia growers with up-to-date information on all aspects of protecting their orchard from pests and diseases.

Feature article

This year’s feature article focuses on the lessons learned from the flood in 2022, tropical cyclone Alfred and other recent extreme wet weather. Research led by Dr Suzy Rogiers, a physiology expert with NSW DPIRD, has provided valuable insights into how macadamia trees respond to submergence and the following prolonged wet conditions. Her findings have highlighted management practices that might contribute to tree survival during these challenging events.

From this research, practical strategies have been identified to help the macadamia industry better prepare for future wet weather. These recommendations aim to support growers in building more resilient orchards that can withstand not only floods, but a wide range of climatic extremes.

This article complements our previous feature on drought resilience, reinforcing our broader goal: to strengthen the industry’s capacity to adapt and thrive under all environmental conditions. Encouragingly, many of the approaches to managing drought and flood resilience share common ground, offering a unified path for growers.

Distribution

The guide is available free to macadamia growers and is distributed to all macadamia processors in Australia. Copies can be collected from the NSW Department of Primary Industries and Regional Development (DPIRD) office at Wollongbar, processors, the Australian Macadamia Society, and selected rural retail stores.
