Exotic Plant Pests and Diseases to Keep an Eye Out This Season

Australian berry growers face potential threats from four major exotic pests: Xylella fastidiosa – A deadly bacterial disease affecting blueberries and Rubus, causing leaf scorch, stem yellowing, and plant death. Japanese beetle – A voracious feeder that skeletonises leaves, damages fruit, and reduces yields by over 60%. Spotted wing drosophila – A fruit fly that lays eggs in undamaged berries, leading to maggot-infested fruit and high crop losses. Brown marmorated stink bug – A polyphagous pest that damages fruit and crops, while also being a nuisance in homes. Growers can protect their crops by maintaining biosecurity protocols, monitoring unusual pest activity, and reporting suspicious findings via the Exotic Plant Pest Hotline (1800 084 881).
