MacAlert May 2024

2024 | Kojetin L, Australian Macadamia Society | Manual/guide

Assess and monitor phytophthora levels in your orchard after months of above average rainfall. Plan your crop inputs for the season ahead to to replenish nutrients, build soil fertility and support tree/crop development. Considerations to make when using ethephon and the best weather conditions to apply. Prepare for frost risk and ensure your orchard is protected. Rules of thumb to ensure your kernel quality is maintained during times of wet weather. Should you consider tree shaking for your orchard? Start thinking about when you will be conducting any pruning and orchard floor repair.

New Flower Blight control option registered

2024 | Kojetin L | Article

The group 7 and 11 fungicide Merivon, which is used for the control of husk spot, has now also been registered for the control of flower blight complex.

MacAlert April 2024

2024 | Kojetin L, Australian Macadamia Society | Manual/guide

Key messages this month include: • Tips for the harvest period. Wet weather has made harvest a challenge. Ensure harvest gear is maintained and follow actions to maximize kernel quality. • Soil and leaf sampling. How and when to take samples of your orchard, and how to get the most out of your results. • Organic inputs. Now is the time to determine organic amendments you will be applying directly after harvest. • Rats, cockatoos and feral pigs. Controlling vertebrate pests during nut drop is essential. Read about management practices you can implement to mitigate these pests. • On-farm crop loss. Understanding where loss is coming from can be invaluable. • Frost mitigation. Consider management practices if you are in frost-risk areas, especially if you have younger trees which are highly susceptible.

Gut contents analysis of macadamia predators: Who eats what and when

2024 | Islam S, Whitehouse M, Mainali B, Beach S, Tay A, Hossain Biswas J, Mottakina Akter M, Zulfiqar Rizvi S | Research report/Update

Predators play an important role in Integrated Pest Management (IPM) without cost to the grower. However, to make the most of this free labour requires understanding which predators consume which pest. Here we undertook the initial analysis to identify the pests consumed by predators in Macadamia using molecular analyses. First, we confirmed the species identifications of the predators, and then we undertook a metagenomic analysis of the gut contents of predators to establish which predators were consuming which pests in the macadamia ecosystem. This is the first of these types of analyses that we plan to undertake.

MacAlert March 2024

2024 | Australian Macadamia Society | Manual/guide

Key messages this month: • Rats. Wet weather has made ideal conditions for rats and mice. • Thrip and Mite damage. Thrip and mite flare ups are often the direct impact from too frequent use of disruptive chemicals. • Kernel Grub. Check storage bins for pests attracted to the odour from broken shells, like kernel grub. • Phytophthora. Phytophthora root rot and trunk canker have a significant impact on production following wet weather. Now is a good time to asses its prevalence. • Nutrition. Long term productivity relies on consistent nutrition which usually includes organic material. You may need to monitor closely more mobile elements such as nitrogen. • Orchard floor preparation is not the only clean up required prior to harvest. Cleaning and checking for any contaminants are essential for food safety as well as a supply requirement with your processor. • There are major benefits to completing a crop loss assessment on all loads coming into the shed. • Are there ways to reduce your harvest period and set the orchard up for the following season sooner?
