2024 Medical Marijuana Pesticide Active Ingredient List

Each year, the Pennsylvania Department of Agriculture updates a list of pesticides that medical marijuana growers and processors can use and sends it to be published in the Pennsylvania Bulletin.

Overview

In Pennsylvania, certain pesticides can be used for growing and processing medical marijuana. To use a pesticide, it must be registered and labeled for use in greenhouses or on food crops. Pennsylvania pesticide registration can be checked here.

PDA evaluates potential pesticide active ingredients for inclusion on this list on an annual basis. Persons seeking review of an active ingredient for addition to this list must submit an application to PDA by June 1st of the calendar year. This submission must include the name of the active ingredient, the EPA registration number for a pesticide containing the active ingredient, and a recent market label for a pesticide containing this active ingredient.  This list will be reviewed and updated September of each calendar year. Deletions of active ingredients will occur on an as-needed basis. Applications may be sent to:

Pennsylvania Department of Agriculture

Attn: Pesticide Registration

2301 North Cameron Street

Harrisburg PA 17110

The PDA will utilize the following criteria when evaluating active ingredients for inclusion on the list:

  • The active ingredient is in at least one EPA registered pesticide, or is exempt under FIFRA 25(b)
  • Pesticides containing this ingredient are labeled for unspecified food or herb crops
  • The active ingredient is exempt from the requirements of a tolerance on all food crops

The PDA may also consider other factors, such as pyrolysis data or whether addition of an active ingredient may likely lead to widespread misuse. This Notice shall become effective immediately upon publication in the Pennsylvania Bulletin. This publication supersedes all previously published Notices related to pesticide active ingredients for use by Medical Marijuana Growers and Processors.
