Growing Cannabis Plants

What are pesticides for cannabis?

Agricultural pesticides are chemical substances used to kill pests and other harmful organisms. Cannabis cultivators may use certain pesticides to prevent damage to their crops by mites, fungi, aphids, gnats, thrips, and powdery mildew. According to a scientific study, more than 350 pesticides are used on marijuana crops. They include:

  • Insecticides
  • Acaricides
  • Fungicides

Other common substances used in marijuana cultivation include herbicides for killing weeds, disinfectants, and other agents. However, while the Environmental Protection Agency (EPA) approved pesticides for hemp, it has specifically approved any pesticides for cannabis. Meanwhile, the Washington State Agricultural Department (WSAD) has a list of allowable and restricted pesticides. This helps ensure growers use pesticides safely.

What pesticides are organic for cannabis?

Some professional cannabis growers rely on organic or natural pesticides to protect their cultivars. This helps yield superior weed strains that were not exposed to toxic contaminants found in commercial pesticides. Common plant-based or organic pesticides used by commercial growers include:

  • Neem Oil
  • Soap Solutions
  • Bugs (E.g., ladybugs and lacewigs)
  • Essential Polis (E.g., rosemary and eucalyptus)
  • Azadirachtin
  • Pyrethrums
  • Bacillus Thurengensis ( BT)
  • Beneficial Nematodes
  • Diatomaceous Earth

Why test for pesticides in cannabis plants?

Strict regulations are in place to monitor growing and pesticide use practices by cannabis farmers. Monitoring involves testing cannabis for pesticide contaminants that are harmful if smoked, inhaled, or ingested. This helps prevent toxic weed from reaching consumers. At HWY 420, we source our flower strains with your health and safety in mind. We rely on growers who use organic pesticides for cannabis cultivation and supply marijuana that passes rigorous testing. The end product is cannabis which gives a clean burn every time.

How to test for pesticides in cannabis?

Testing for cannabis pesticides is required for growers to comply with state safety standards for medical and retail marijuana. Screenings are carried out by a certified third-party lab. The entity must be approved by the Washington State Liquor and Cannabis Board (WSLCB). Tests are done to confirm only pesticides allowed by WSAD are used and within the permitted levels. Cannabis crops that failed the quality control tests are subject to recall and disposal. The same is the case if testing detects pesticides that are not allowed.

Even though insecticides such as bifenthrin and acequinocyl are allowed, trace amounts in marijuana can be toxic when inhaled. Our weed dispensary sources only high-grade strains that pass the quality control testing for cannabis pesticides.
