A Farmers Weekly Academy on turnip yellows virus (TuYV) has been launched, helping growers understand and manage the costly disease.

The free online course summarises the latest understanding of TuYV, with information on all the key aspects, from identifying it to controlling it.

The damaging virus is the most important viral disease in oilseed rape, causing up to 30% yield losses, yet it is one of the least understood.

Managing the TuYV requires an understanding of the aphids that carry it, as well as the disease itself.

With the two-year ban on neonicotinoid insecticide seed treatments now in force, control of the aphids now relies on autumn-applied foliar treatments.

Go to the Farmers Weekly Academy to take the module and test your knowledge on this crucial area of oilseed rape management.

You can also gain two Basis points and two NRoSO points by completing the academy.
