FAQ – What if it goes wrong?

Of the 1,400 worldwide releases against weeds, less than 1% produced non-target effects and all bar two were predicted by scientists prior to release. However, the predicted damage to, in some cases rare species, was deemed to be an acceptable risk at the time, given the scale of the problems. However, given the same data and situation, it is highly unlikely that today’s decision makers would authorize such a release.

The care taken prior to releasing a natural control agent is in stark contrast to the wholesale importation of exotic species, either as pets or garden plants and their pests, or as stowaways within many commodity crops.
