In Australian canola crops, turnip yellows virus is the one of the most widespread and economically damaging viruses, and over the past decade, epidemics have commonly occurred in different regions causing considerable losses.  

Turnip yellows virus is particularly challenging to manage because it is transmitted by green peach aphid and needs just a few aphids per plant to cause substantial spread. 

A GRDC investment led by the Department of Primary Industries and Regional Development in Western Australia has been looking at management options and developed new data and guidelines around seed treatments and foliar insecticides. 

In this episode, we’re joined by senior research scientist Ben Congdon to find out more.
