Turnip yellows virus (TuYV, formerly known as beet western yellows virus) is an obligate plant parasite transmitted exclusively by aphids, specifically the Green peach aphid. TuYV systemically infects canola plants and cannot be sprayed-out post-infection like a fungal disease.

DPIRD research scientist Dr Ben Congdon, in collaboration with Cesar Australia, is testing an early warning system for TuYV epidemics in Australian canola crops. By detecting migrating aphids carrying TuYV using yellow sticky traps and a rapid and sensitive RNA detection technique, this system may provide virus risk information to growers that enables proactive TuYV control strategies and prevent widespread TuYV infection and damage in canola crops.
