State regulators have proposed rules that would further restrict which pesticides can be used to grow marijuana to those that are least harmful and already are allowed on crops intended for human consumption and tobacco.
The draft rules mark the state’s latest effort in a process that began about two years ago but has dragged on amid industry pressure and lack of guidance from the U.S. Environmental Protection Agency.
Currently, the state allows more than 200 pesticides on marijuana, but the new rules would pare it to about 75, officials say, although more can be added.
The proposal would limit allowable pesticides to those so nontoxic they do not need to be registered with the federal government or those so safe to use that no residue level needs to be determined.
The rules were proposed last week, and marijuana industry representatives said Monday they are reviewing them.
