We have an excellent international track record for discovering, safety testing, and assisting governments release natural control agents. We have been working on invasive weed biological control projects since 1947 and have played a vital role in the development of an International Code of Conduct.

This was done against the recommendations of scientists at the time and would never pass the stringent pest risk analyses applied globally today. Find out more about the cane toad >> |
