Abstract
Powdery mildew has become more prevalent in WA wheat crops over the past few years, particularly late in seasons. In 2015, it was widespread and damaging on wheat crops in the northern and central wheatbelt and in the Esperance region. The degree of damage and best management has not been tested in detail for more than 15 years in WA. The disease persisted through winter and into spring and proved difficult to control in 2015 crops. Prominent questions facing growers and advisers during 2015 centred around potential yield losses, profitability of applying fungicides, best timing and product, value of multiple sprays and potential risk of fungicide resistance. This paper investigates impact of fungicide management of powdery mildew infection that occurs after stem extension.
