Macadamias

Welcome to our Macadamias Hub

Yates Hort & Ag brings together the expertise of Organic Crop Protectants, Seasol Hort & Ag, and Yates Commercial to offer Australian macadamia growers a comprehensive range of crop protection, biostimulant and nutritional products. As members of the Proteaceae family, macadamias (Macadamia integrifolia, M. tetraphylla and hybrids) perform best under a low-phosphorus, biology-building management approach. Boron and zinc play critical roles in flowering and nut set, while potassium and calcium are essential for kernel development and fill. Key seasonal challenges include husk spot and the macadamia spotting bug complex, making an integrated approach to crop nutrition and protection essential for maximising orchard productivity and nut quality.

All products are independently tested for efficacy and safety, with numerous APVMA registrations and compatibility verified under Integrated Pest & Disease Management (IPDM) systems.
