Treatment minimum standards

There are set minimum standards for the application of BMSB treatments. Treatments applied for biosecurity purposes are part of managing the risk of introducing exotic pests and diseases.

It is important that treatment providers understand these requirements as treatments to manage risk are only effective when conducted correctly. These standards outline best practice methodologies for applying biosecurity treatments.
