The yellow dwarf diseases of cereals have now been divided into two groups, barley yellow dwarf virus (BYDV) and cereal yellow dwarf virus (CYDV)... Where resistant varieties are not an option the management of aphid activity in crops especially early in the season to prevent its spread and or delayed sowing to avoid the main aphid flights in the autumn can reduce YDV infection... Later sowing to avoid the main aphid flights will reduce the incidence of YDV but this needs to be weighed up against possible yield reduction from delayed sowing...

For example, at Dubbo 407 mm of rain fell on 68 days (39 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... The pattern encouraged rapid vegetative growth of crops and was ideal for the build-up and spread of the major chickpea pathogens... Ascochyta blight (AB, caused by Ascochyta rabiei ), Botrytis grey mould (BGM, caused by Botrytis cinerea ), Phytophthora root rot (PRR, caused by Phytophthora medicaginis ) and Sclerotinia rot (caused by Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops...
