Matthew Addison's career trajectory in the South African deciduous fruit sector began with his role in pioneering integrated pest management (IPM) practices. Originating from Johannesburg, Addison's connection to the fruit industry was established early on through his father's involvement with the Appletiser plant. His academic path led him to a BSc in botany and entomology from the University of KwaZulu-Natal, followed by a master's in forest entomology. The inception of his career in pest management was marked by an opportunity with the South African Apple and Pear Producers' Organisation, now known as Hortgro Pome, where he was tasked with initiating an IPM programme.
The introduction of IPM in the pome-fruit industry was a response to the challenges of pesticide resistance, driving the need for alternative pest control methods. Addison's engagement with global experts and institutions, such as the University of California, Davis, and Oregon State University, enriched his understanding and approach to managing pest resistance, particularly with the codling moth. His efforts in monitoring and data collection laid the groundwork for the adoption of pheromone disruption and the exploration of biocontrol agents.
Unifruco Research Services' establishment coincided with significant advancements in biological control, notably the accidental discovery and successful implementation of Neoseiulus (Typhlodromus) californicus for mite management. Addison's tenure also witnessed the exploration of sterile insect techniques, marking a pivotal moment in the industry's approach to pest control. Despite the eventual discontinuation of the codling moth project, Addison views the sterile insect technique as a valuable, yet underutilized, tool in IPM.
Throughout his career, Addison has witnessed the evolution of pest management strategies, acknowledging the ongoing reliance on chemical solutions and the potential for further integration of biocontrol methods. His retirement from Hortgro does not mark the end of his involvement in the industry, as he continues to contribute to Hortgro Science as a crop protection researcher. Addison's reflections on the past and insights into the future underscore the dynamic nature of pest management in South Africa's deciduous fruit industry and the continuous need for innovation and adaptation.
