Steve, I've been a dog owner for many years and have had to use permethrin at times when flea infestations are bad; and I am aware it is not safe for cats which I don't have. I feel much safer with the chemicals that I apply than what may be applied in foreign countries to much of the produce we find in our stores.
As for the growth regulator it sounds fairly benign and it has a fairly short life once exposed to sunlight for an extended period. I'm just hoping it will be effective enough to slow down the rapidly growing infestations of whiteflies and spider mites.
Bill
