OREGON: The Oregon Department of Agriculture is warning marijuana growers to stop using illegal pesticides, while the state scrambles to put together a list of acceptable chemicals.
The federal government puts pesticides through tests that determine in what context a chemical may be used in agriculture and how much may be used. Those accepted uses are then listed on the label of the pesticide.
However, because cannabis is an illegal substance according to federal laws, there are no approved pesticides to use in marijuana cultivation. So, while many growers use pesticides, the application is technically against the law.
