Neonicotinoid resistance in green peach aphids: a setback for seed treatments
Author: Lilia Jenkins and Associate Professor Paul Umina (Cesar Australia), 2023-04-24T09:00:00+10:00New research from Cesar Australia investigating the implications of neonicotinoid resistance in the green peach aphid (Myzus persicae) could change how and when these chemical treatments are best used in broadacre crops. The green peach aphid is a species of particular concern to the grains industry, as it acts as the main vector of a number of economically damaging plant diseases, such as turnip yellows virus (formerly known as beet western yellows virus) in canola and pulse crops.
