§ 5716. Homogeneity Testing of Edible Cannabis Products (a) The laboratory shall analyze a sample of edible cannabis product that contains more than one serving per unit to determine whether the edible cannabis product is of homogeneous THC content. (b) The laboratory shall perform homogeneity testing when the first batch of edible cannabis product is tested before entering the retail market. Once the initial batch of the product passes homogeneity testing, and provided that the process for manufacturing and the composition of the edible cannabis product remains the same, a batch of edible cannabis product shall be tested for homogeneity every 6 months thereafter. (c) A sample of edible cannabis product shall be deemed to have passed homogeneity testing if the relative standard deviation of THC concentration between the samples collected does not exceed plus or minus 10%. (d) If a sample fails homogeneity testing, or the laboratory fails to perform homogeneity testing as required by this section, the batch from which the sample was collected fails homogeneity testing and may not be released for retail sale. (e) If a sample passes homogeneity testing, the laboratory shall perform all other analyses required under this chapter. Authority: Section 26013, Business and Professions Code.

List of Pesticides Allowed for Use in Marijuana Production
Updated List of Pesticides Allowed for Use in Marijuana Production
The Washington State Department of Agriculture (WSDA) has recently updated the list of pesticides that are allowed for use in marijuana production in Washington State, based on criteria previously established by WSDA.
The WSDA has added 12 pesticides to the list of allowable products. Pesticides containing two new active ingredients (Cinnamaldehyde, Gliocladium catenulatum Strain J1446) were added to the list. Most of the pesticides that were added to the list contain active ingredients that were already allowed for use in marijuana production.
Some pesticides are labeled for application to soil or to crop plants, while some pesticides are labeled for application to both soil and crop plants (e.g., insecticides, fungicides). Other pesticides include herbicides labeled for direct application to, and control of, unwanted plants (i.e., weeds). Remember to read, understand, and comply with all applicable label directions and precautions when using any pesticide.
