Biosecurity

Biosecurity represents a range of activities and measures to assist in preventing, responding to and recovering from pests and disease incursions. Measures can be implemented across a range of levels from international, national, state, regional, local and farm level. Australia has been fortunate in that previously its geography granted a level of isolation from the pests and diseases which affected foreign plant-based industries. This has now changed as faster and more accessible international trade and travel has increased the risk of exotic plant pest incursions.

The nursery industry is particularly at risk from biosecurity events given its broad geographic spread, the wide variety of crops grown, and the trade markets it engages in. Such events may not only put our own industry at risk but also other plant-based industries and the environment.

To enable industry preparedness in prevention, response and recovery from biosecurity events, GIA has adopted a proactive approach. Investment and attention have been expended on biosecurity. Examples include

  • The development of the Australian Plant Production Standard (APPS) incorporating a dedicated Biosecurity plant protection program, BioSecure HACCP
  • Development of pest fact sheets and contingency plans. Industry threat specific contingency plans have been developed for significant exotic plant pests to inform the development of response plans. These plans can be accessed HERE.
  • Signatory to the Emergency Plant Pest Response Deed (EPPRD) and
  • Active participation in various management and consultative committees.

This page has resources which have been developed to assist industry in meeting its biosecurity obligations.

Testing irrigation water qualityIrrigation water quality is a critical factor for nursery container production. There are many factors which determine the quality of irrigation water, some of which include alkalinity, pH and the level of soluble salts. This fact sheet includes a discussion on the importance of water testing.7 Dec 2025
Testing Sterilisation Effectiveness 2011Good irrigation water quality is a keystone to producing quality nursery stock, and most water supplies requiresome form of treatment to make them suitable for nursery use. Water can be treated for four types of contaminates – particulate matter, pH, salts and pathogens. The following article discusses how to test for the effectiveness of treatments applied to kill or remove pathogens.7 Dec 2025

Water Retention Efficiency Of GM 2010Water retention efficiency (WRE) is a measure of the ability of a growing media to hold water applied from irrigation and this influences how long the irrigation must be run to wet up the media. An Australia wide survey has shown that the WRE of commercially available growing media varies considerably, and suggests that the choice of growing media can influence water consumption and the quantity of nutrient runoff produced from a sprinkler or drip irrigation system.7 Dec 2025
