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.

Macadamia virtual field walk

In May of 2022 QDAF hosted a virtual field walk showcasing the macadamia rootstock trial and phase II of the macadamia planting systems trial.

MacAlert - May 2022

2022 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Have you applied for disaster relief if eligible? • Following the wet season conduct a survey of your orchard for long term impacts including Phytophthora. • There are a number of ways to plan crop inputs for the season ahead. • Returning husk back to the orchard is one of the most cost effective ways to replace many nutrients. • Do you know the details of the organic matter you are purchasing? Compost, mulch, manure, soil conditioners, etc? • Continue to audit harvest efficiency and make adjustments as require, especially for machinery in wet conditions. • With more humid conditions and nuts at higher field moisture, it is vital to manage nuts post-harvest. • Have you finalised your plan for post-harvest management?

Managing storm damage

2022 | Australian Macadamia Society | Fact Sheet

This fact sheet summarises ways growers can build storm resilience and recover more quickly from storm damage.

MacAlert - February 2022

2022 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Following rain, late season monitoring may be required. • Botryosphaeria is part of a group of fungi causing increasing damage in many tree species, including macadamia. • With prolonged summer rain and/or a heavy crop, you may need to adjust your nutrition program. • Pre-harvest clean-up ensures minimal old nut, sticks and debris remain on the orchard floor and dramatically improves harvest efficiency. • Conduct pre-season audits for you processor in advance, allowing time for any corrections before harvest. • Monitor for maturity. Husk colour is an on-farm indication of maturity but your processor will perform an accurate assessment. • With harvest around the corner, ensure equipment is in good order. Preventative maintenance is the key to reducing breakdowns during the season.

MacAlert - April 2022

2022 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Disaster grants and loans are available – do not rule out your eligibility; ensure you have plenty of photographic evidence. • If you conduct soil and leaf tests during Autumn, book or organise these now to assist in determining organic amendments to be applied following harvest. • Monitoring and managing vertebrate pests such as cockatoos, rats and pigs are essential during nut drop. • Consider orchard access and machinery performance in relation to weather conditions. • Six ways to prevent quality (and money) loss with simple ventilation of harvested nuts proving effective. • Conducting harvest efficiency audits and analysis of on farm crop loss may prove invaluable to your farm management. • As harvest continues and the weather cools, start thinking about frost mitigation if relevant to your region and begin planning your canopy management strategy.

Ground cover

2022 | Australian Macadamia Society | Fact Sheet

The orchard floor is the engine room of any orchard. One of the best options for improving long-term orchard floor productivity and sustainability is to improve ground coverage. This fact sheet outlines the benefits of ground cover and considerations for management. Each growing region is different and a tailored solution for your orchard and the resources you have available will be required.
Healthy ground cover provides physical and biological benefits, maximises natural crop inputs and improves resilience.

MacAlert - March 2022

2022 | Australian Macadamia Society | Manual/guide

• Recovering from heavy rain and flooding – short and long term response. • Assess Phytophthora root rot and trunk canker over the next few months following wet weather. • Continue with a consistent nutrition program, which may need to be increased due to the wet weather. • Orchard floor preparation, cleaning and checking for any contaminants are essential for food safety. • Safety audits are a possibility WH&S QLD have informed the AMS that they intend to audit macadamia operations. • There are major benefits to completing a crop loss assessment. • Consider ways to reduce your harvest period and set up the orchard for the following season.
