Test Benefits

We take pesticides very seriously at Encore Labs. That’s why we utilize two different analytical techniques to attack the wide variety of chemical structures present in pesticides. This gives us the ability to reliably detect concentrations far lower than state action limits to prevent production issues that may occur after extraction and concentration.

What We Test For


Residual Pesticides Testing

  1. The laboratory analyzes a portion of the representative sample of cannabis or cannabis product to determine whether residual pesticides are present.

  2. The laboratory reports whether any pesticides are detected over the limit of detection (LOD) and reports results over the limit of quantitation (LOQ) in micrograms per gram (μg/g) on the COA. The laboratory indicates “pass” or “fail” on the COA based on state-defined action limits.

  3. The sample shall be deemed to have passed residual pesticides testing if detected amounts are below the limit for all pesticides including but not limited to Abamectin, Acequinocyl, Bifenazate, Imazalil, Imidacloprid, Myclobutanil, Paclobutrazol, Spinosad, Spiromesifen, Spirotetramat, and Trifloxystrobin.

  4. If a sample fails residual pesticides testing, the batch from which the sample was collected fails pesticides testing and shall not be released for retail sale.
