A lot went down in the cannabis pesticides world in 2020. Health Canada‘s Pest Management Regulatory Agency (PMRA) gave new approvals for, or re-approved, nearly two dozen sprays for cannabis cultivation. In a much needed 2020 recap, let’s explore new and old pesticides used on cannabis.
Here today, gone tomorrow (and back again)
Some pesticides were previously removed from the PMRA’s list of approved cannabis pesticides. A dismissal that came as no surprise was the fungicide, Prestop. This writing author speculated that a batch of recalled cannabis was connected to a harmless growth of the fungicide slightly before it was pulled. But, sometime during 2020, Prestop, as well as four other pesticides, were re-approved. Further dismissals in 2019 included three sprays by Neudorff. However, their pesticides were once again approved for use on cannabis in Canada in 2020.
That brings us to Actinovate SP by Monsanto partner, Novaenzymes Bioag. This spray was approved for use on cannabis in 2014. And in 2018, Novaenzymes requested that Health Canada remove its permission for cannabis cultivation. But, in 2020 that decision was clearly reverted since Acinovate SP is once again available to cannabis growers in Canada. In addition to this, the PMRA agency more recently approved a general insecticide by Novaenzymes Bioag.

New cannabis sprays in 2020
Currently, 47 pesticides are approved for use on cannabis in Canada (at the time of writing.) In total, there are nine new active ingredients to cover in this series. Beyond the aforementioned sprays, there have been a few other exciting additions. Two of these consist of viruses, which will benefit any cannabis farmers who have been plagued by cabbage loops or corn earworm infestations.
