In everyday life there is an element of risk in everything we do. In most instances as grape growers, we don’t operate in isolation; we are very connected to our neighbours, our regions, neighbouring grape growing regions, between states, and for some of us, internationally. Along with this connectedness comes a risk of pest and disease incursion. In order to be prepared to mitigate these potential incursions, we need to be aware of how pests and diseases infect our vines and the methods (vectors) by which these pests and disease can be moved onto and off of our properties. We also need to understand the practices we as operators undertake which have the potential of increasing or decreasing the likelihood of an incursion.
