State warns Oregon MJ growers about unapproved pesticides

Three of Oregon’s government agencies have warned marijuana cultivators about using pesticides not approved by the state for use on cannabis crops.

In a jointly signed letter addressed to “Dear Cannabis Producer,” the directors of  the Oregon Department of Agriculture, Oregon Health Authority and Oregon Liquor Control Commission wrote on Monday that producers can meet Health Authority pesticide standards but still be in violation of the state’s Pesticide Control Act if any levels of illegal pesticides are found.

 The letter was cosigned by Lisa Charpilloz Hanson, acting director of ODA; Lynne Saxton, director of OHA, and Steven Marks, executive director of OLCC.

The state implemented new cannabis testing rules on Oct. 1, and since then, the letter suggests, many product samples have failed their tests.

In early November, Oregon issued a pesticide warning for three strains of cannabis, Dutch Treat, Pleeze and Dryzl.

The directors advise growers to use only pesticides listed on the Agriculture Department’s cannabis and pesticide guide, which was updated Oct. 17 and now contains 319 approved pesticides.

    Why would people break the law by using unapproved pesticides ? Marijuana is legal now , you greedy growers do it right or pay fines and possible jail time … It is about time the State of Oregon steps in and begins to collect our share of your profits …

      It is more complex than “greedy growers” using unapproved pesticides. For example, many natural pesticides (that can be safely used as directed) like neem and tea tree oils are not on this list, it only lists branded company products ($$) . And the state of Oregon has officially said it is illegal to use anything that isn’t on this approved list. It is a smart move to protect consumers, but we have a long way to go before the list is truly comprehensive and includes natural pest prevention and treatment options. We all look forward to more comprehensive research about what is safe for consumers

      The list is in the best interests for growers and consumers alik . That being said many products that are currently used on food crops up to the day of harvest are way more harmful then anything on the approved list from the OHA & OLCC & ODA. It is mind bogglingly to me how many items are on the approved list with pytherin as the main ingredient. How can they possibly fine growers for using commercially available products that have nothing in them other then plant oils? The industry is new and will have many growing pains as it relates to pest control methods and Integrated Pest Management. As a OMMP grower and cinsumer I’m always cincious and very selective about what is applied to my crop, and what stage said products are used for obvious reasons. What I fail to understand & never will is how the food agricultural industry gets to live by different rules then marijuana priducers? Wash what you eat is my best advice because I guarantee you if you go to a grocery store and grab a tomato even if its in the “organic” section and have it tested for pestacide levels you’d likely not want to eat it. Our state has much work to do as it relates to safe products for marijuana crops and when to use them.

    There is no fungicide or pesticide that has been tested and approved for use on any crop that could be combusted and inhaled. Read the Cannabis Internal Management Directive PDF file on this site. It states that being on the list does not mean the substance is safe to use on Cannabis and this site cannot be held liable for any health damages caused by listed products.
