The past, present and future of integrated pest management in New Zealand fruit cropsPests and subsequently, the use of pesticide to deal with pests, has long been a problem for the New Zealand Pip Fruit industry, especially when it sought to gain access into new, high-value export markets. However, since the mid 1990s, the work carried out by Dr Jim Walker and his team has contributed to more than a 90 per cent reduction in insecticide use (kg/ha) by local apple growers. This includes the introduction of new natural enemies through to the development of selective pest management and use of semio-chemicals (pheromones) to support greater use of biological control in apple orchards. The development and implementation of these innovative pest control tactics are now central to today’s pest management systems. Dr Jim Walker, entomologist and Principal Scientist with Plant and Food Research, talks about this research as well as the future sustainability and biosecurity threats facing the apple industry.

About the speaker:

Plant & Food Research scientist Dr Jim Walker leads a team of researchers focused on developing innovative tools and techniques for managing pests affecting the New Zealand horticultural industry. During his 30 year career, he has been involved in the development and introduction of the Integrated Fruit Production (IFP) programme in the New Zealand pipfruit sector. The IFP programme has resulted in the sector adopting pest monitoring, pest prediction models and alternative control methods, enabling apple growers to substantially reduce their use of pesticides. More recently Dr Walker has been involved with development of the sector’s ‘Apple Futures’ programme, focused on meeting the demand from consumers for high quality, residue-free fruit. He has also provided crucial guidance for the application of IFP to other sectors including wine grapes, summerfruit, citrus and onions.
