NY134 - Study Tour

This report is the result of a study tour in July 1991. This report reviews biological control/IPM of major glasshouse pests in Europe and North America and discusses the prospects for their control in Australia, It does not deal with plant pathogens and concerns only protected crops IPM in ornamentals is not as well established as IPM in glasshouse vegetables, and so one must be careful in drawing conclusions. However it is clear that the trend away from chemical control is irreversible and that much research overseas is being directed to the use of natural enemies in ornamentals.
