OMG HanabataDays, best to not continue your Fake News posts on Pyrethrins (organic base) or any other pesticide.  There are no approved pesticide by the EPA for marijuana, period.  Oregon, Washington State, Colorado have attempted to have EPA approve some of the pesticides and have been advised that as long at marijuana is a Schedule I illegal drug, the EPA will not review any pesticide.  You are aware of the Paraquat (herbicide) spraying and human impact in Mexico and Central America.  Use of Pyrethrins could be worst.
