BYDV reduction…delayed drilling and tolerant varieties
Written by Siobhan Walsh, Agriland
Barley yellow dwarf virus (BYDV) is a big risk to all cereal crops and since the banning of neonicotinoids in the EU and the development of resistance in aphids to pyrethroids, the risk is a lot higher in winter cereals and can reduce yield by up to 2t/ha in cereal crops.
Speaking on the Teagasc Online Crops Forum on Thursday evening (September 10), Tim O’Donovan of Seedtech spoke about alternative management of BYDV.
The first thing he stated is that it is important to know the life cycle of aphids and what influences them. This in turn will result in delaying drilling dates.
