“Biosecurity” is a general description for a series of measures designed to protect individual farming properties, businesses and the nation as a whole, from the entry and spread of exotic pests. This is done by using exclusion, eradication and control measures. This 2-page fact sheet covers the role of Plant Health Australia (PHA) in developing a National Biosecurity Plan for the Vegetable Industry that details the major threats and the practices that will minimise the risk of exotic pest incursions. The fact sheet also gives details of practical steps (referred to as “biosecurity strategies”) that can be implemented by vegetable growers. Biosecurity is not only important for the profitability and sustainability of individual businesses, but for other vegetable/horticulture/agriculture businesses in their region and for the whole vegetable industry.
