Wheat agronomy (nitrogen rate and timing BYDV) trials - Conmurra locations
Aims

To assess the impact of applying Nitrogen at different rates and timings and insecticide for the control of BYDV on grain yields of selected wheat varieties.

Key messages
  • In high rainfall areas, the inclusion of an insecticide to control aphids, and therefore reducing the incidence of Barley Yellow Dwarf Virus (BYDV) should becoming common practice.
  • Yield responses continue to be seen by controlling BYDC (particularly in susceptible varieties).
  • In  2011, the control of BYDV also appeared to  improve the response to later applied nitrogen.
