Abstract

Grape phylloxera (Daktulosphaira vitifoliae, Fitch) is an encroaching problem for the Australian wine industry with four new outbreaks recorded in the past 5 years. Whilst quarantine- and phylloxera-resistant rootstocks are the recommended long-term management strategies, there are at present no short-term options for recently infested vineyards. In this study, an assay for assessing the impact of the systemic insecticides thiamethoxam (Actara®; two applications at a concentration of 2000ppm active ingredient) and imidacloprid (Confidor®; one and two applications at a concentration of 2000ppm active ingredient) on suppression of phylloxera populations on grapevine roots was developed.
