Barley yellow dwarf: incidence and natural spread in wheat locations
Aims

To assess the natural incidence of two BYD strains (PAV and RPV) in an insecticide treated field and to evaluate the effects of diseasse 'hot spots' (infected plots with BYD) and infection rate on neighbouring plants.

Key messages

An extremely highl level of barley yellow dwarf disease was recorded in Victorian cereal crops in 2013; 40-70 per cent infection.

A high number of aphids flying into crops from neighbouring vegetation reduced the effectiveness of the insecticides.

Regular crop monitoring is essential to maximise yield while minimising the effects of aphids and BYD spread.
