Can I apply pesticides and fungicides with Myco Supreme?

We recommend asking us before using fungicides together with Myco Supreme. As a rule of thumb, non-systemic fungicides, herbicides and insecticides are generally compatible with Myco Supreme, while many systemic fungicides are incompatible. When drenching soil with fungicide, we recommend doing so at least two weeks prior to inoculation or at least four weeks after planting. To ensure compatibility with other treatments, please contact Trifecta support at When in doubt, our staff is always available to help.

In general, we recommend not using synthetic pesticides or fungicides at all. There are lots of natural products that will have the same effect and that are better for both you and your plant’s health. We support organic and natural farming practices, especially when it comes to cannabis which is often provided to medical patients.
