Off-label use. An alternate response is ‘show that it’s safe’.
For the above, floramite, what is the half-life for bifen-azate. And then, what is a safe amount for the various consumption modalities? Do we know? Inhalation, ingestion? How do you ensure safety standards are met? What are the effects of acute -v- long term exposure? Do the safety limits vary based on exposure duration?
FWIW:
4.4 PPM Bifenazate LC50 for inhalation over a four hour period. LC50 refers to the lethal dose where 50% of the test subjects expire. The SDS does not account for combustion byproducts.
There are horticultural practices that can achieve similar performance, albeit, with some difficulty, extra attention, and effort. Although, based on the three generation hypothesis, that also seems like a bunch of extra work as the successive generations, as proposed, would require a sufficiently sanitary environment to wean them off those pesticides.
Personally, off-label use is a liability. We’ll avoid until such products are labeled for such use and even then would question whether they are appropriate for the circumstance. Part and parcel of ‘CAREFUL’ use of pesticides.
