2023 | Australian Macadamia Society | Manual/guide

Key messages this month include: • Monitor weekly to fortnightly for pests and diseases that affect flowers depending on the risk to your orchard. • If you have known hotspots, pay close attention to them first. Best practice is to select controls that have the least impact on non-target species. • If you’re still harvesting, be aware of withholding periods and products that you cannot use if you are still going to pick up nuts (such as Sivanto Prime). • With the number of Varroa mite infested sites increasing, make sure you know where your honey bee hives are coming from. • Tree water demand is increasing, you need to put in place every moisture retention strategy you can. • The AMS website has a weather monitoring page where you can see real time conditions on a large network of weather stations located on macadamia orchards. • You are likely to be doing some sort of canopy management over the next few months. Remember to be safe. Ensure that all staff are suitably trained. • There are so many benefits of letting ground cover grow. Consider reduced mowing strategies to save costs and improve orchard health, leaving a habitat for beneficials and improving orchard floor moisture retention as we head into drier months ahead.

• Monitoring should be underway for pests and diseases that impact flowers. Cutting back on monitoring is a risky strategy, the small investment is invaluable. • In southern regions, monitor for lace bug. Previous hotspots are a good place to start. • In northern regions, monitor for flower caterpillar. Eggs are the first sign of infestation. • Flower blights. If your orchard has a history of flower diseases and weather conditions are conducive, you may need to apply a preventative fungicide. • Husk spot. Shortly after flowering, husk spot control is important if your orchard has a history of the disease, has stick tights and/or susceptible cultivars. • Rats are always an issue, but they are reported to have been more damaging this season following wet years. You have an opportunity at the end of harvest to reduce populations. • As the weather warms, tree nutrition and water requirements increase. An El Nino is expected to form in the second half of the year and conditions will likely be hotter and drier. • At end of harvest season, conduct a thorough audit of what needs to be repaired and make notes while it’s fresh in your mind of how machinery performed. • Do you have a plan to bring managed pollinators into your orchard? Honeybee and native beehives have different distribution and management considerations. • As the weather warms there is an opportunity to plant cover crops which improve orchard productivity and resilience. • Winter is the best time to prepare for fire season and as a landowner you are responsible for this preparation.

Key messages this month include: • We are heading into the peak pest and disease monitoring period. The impacts of this year’s weather conditions need to be factored into your management. • There is still time to adjust nutrition before flowering, so discuss your soil/leaf sampling results with your consultant and develop a nutrition program. • With current prices, the incentive to harvest and its cost are being weighed by each grower. Your grower liaison can help sample in blocks you aren’t sure are worth picking up. • Do you understand how kernel assessments on samples from your consignments are conducted and what this means for grower payments? The AMS is holding kernel assessment workshops. • Winter is the best time to prepare your farm for the fire risk season ahead. • Are you ready for spray activities over the next few months?

MacAlert May 2023

2023 | Australian Macadamia Society | Manual/guide

Key Messages this month include: After months of above average rainfall, assess Phytophthora levels in your orchard. There are a number of ways to plan crop inputs for the season ahead, soil and leaf sampling and crop load assessment. When purchasing organic matter, do you know what you are purchasing? Heading into winter, monitor weather conditions for frost and apply frost protectant if required. Have you considered tree shaking? There are a range of efficiency and orchard health benefits. Continue to audit harvest efficiency and make adjustments as required in the orchard and shed. This season might be the time to consider major canopy rejuvenation if you have the reserves to do so. Analysis of consignment reports is most helpful when done block by block and can direct rationalisation with current farm gate prices. The BOM predicts a likely return to El Nino conditions over the coming months.
