To assess the impact of BYDV on wheat yield and also the effect of a range of fungicide treatments on wheat yield during 2009.
• Significant yield increases were measured at Conmurra by controlling aphids to reduce the impact of BYDV.
• A range of fungicide treatments, applied at GS31 increased grain yield in wheat at Conmurra by about 0.8 t/ha
• High levels of black point occurred at Millicent and allowed good ratings to be made.
At the higher rainfall sites such as Conmurra, consideration should be given to spraying to control aphids in order to reduce the early infection of cereals by BYDV. At lower rainfall sites such as Frances this may only be a viable proposition in years with high summer and autumn rainfall that may allow increased aphid survival. The development of new varieties with increased tolerance to BYDV will reduce this need to spray. CSIRO has wheat lines in their breeding program that have this tolerance. While fungicides would normally be used when disease is present, there are some circumstances where yield increases can be recorded even in the absence of disease.
