Abstract
The unusually wet season across south-eastern Australia in 2010–2011
saw grapegrowers exhausted after endless hours of spraying, often in
vain, to control the dreaded trifecta of downy mildew, powdery mildew
and botrytis bunch rot (botrytis). Mildew infection during flowering
and fruit set damaged grape berries providing infection sites for
the opportunistic ‘wound’ fungi that cause bunch rot. However, the
interaction between the diseases was not always detrimental. There
were reports that defoliation caused by downy mildew increased
air circulation in the canopy which, in turn, reduced the severity of
bunch rot. Nevertheless, the pressure on vineyard managers to act in
controlling these diseases was relentless, even when certain actions,
with hindsight, proved fruitless.
