ABSTRACT

The viability of New Zealand’s plant-based industries depends on the efficient production of high-quality produce for export. Development of natural systems for disease control will enhance the reputation of New Zealand produce on world markets and protect the market access. Biological control provides an alternative to the use of synthetic pesticides with the advantages of greater public acceptance and reduced environmental impact. The use of microorganisms as biological control agents (BCAs) seeks to restore the beneficial balance of natural ecosystems which is often lost in the crop situation.
