Abstract

Grapevine downy mildew (Plasmopara viticola) was first detected in commercial vineyards in the Swan Valley region of Western Australia (WA) in 1998 and has now spread to all grape-growing regions of the state. This paper uses a bioeconomic model linking weather, spread, infection development, variable production costs and revenue to estimate the costs of P. viticola over time. Results indicate mean annual costs of AUD $7.3 million per year, equivalent to a 1% drop in the gross value of WA grape-growing industries. Cumulative losses since the disease became established are estimated to be AUD $140 million.
