Two Wash. State Agencies Partner to Speed Testing Marijuana for Illegal Pesticides


September 18, 2016

[Press Release] OLYMPIA – The Washington State Liquor and Cannabis Board (WSLCB) and the Washington State Department of Agriculture (WSDA) today announced that they have an agreement in place that will allow the two agencies to work together cooperatively to test for illegal pesticides on marijuana. The WSLCB will pay for the specialized equipment necessary to test for pesticides and two WSDA employees who will be dedicated to carrying out pesticide tests. This agreement is for pesticide enforcement, random testing and testing when illegal pesticides are suspected. 

“This agreement will significantly expand the state’s ability to test for pesticides,” said WSLCB Director Rick Garza. “Testing for pesticides is a complex and costly process. Labs need specialized equipment and highly-trained staff to carry out the tests. This agreement will satisfy those obstacles. It will send a strong message to any producer applying illegal pesticides that they will be caught and face significant penalties, including possible cancellation of the license.” 

Under the terms of the agreement, WSDA will analyze an average of 75 samples per month covering a spectrum of 100 or more pesticides. The turnaround time for analytical results will be 15-30 calendar days. 

WSDA is the state agency responsible for regulating pesticides used and distributed in Washington. Currently, marijuana growers may use any of the 330 pesticides that WSDA has determined are allowed for use on marijuana, as long as all applicable label directions are followed. The list of allowed pesticides is available on the WSDA’s 
Pesticide and fertilizer use on marijuana in Washingtonwebpage. The list is also available by using the Washington State University Pesticide Information Center Online (PICOL) database.

“This new agreement will increase consumer protection in the emerging marijuana retail industry,” WSDA Director Derek Sandison said. “WSDA is pleased to partner with WSLCB to ensure that pesticide use in Washington’s marijuana production follows all applicable laws and regulations.”
