Horticultural oil is a petroleum distillate. Neem oil is a plant extract from the Neem Tree. It grows in India. There is such a thing as food grade neem oil intended for human consumption. Horticultural grade neem oil is approved for same day harvest by most organic food certifying agencies. Neem oil's mechanism is hormonal. It is an anti feedant. It is also anti-fungal. It kills fungus gnats. You can not in ethically spray petroleum distillates on cannabis and call it organic nor is it fit for medical use. I could go on but a quik google of neem oil will bring up planty of info.

I'm not sure where you get your information from, but you are incorrect. There are both petroleum-based horticultural oils and vegetable-based horticultural oils. I can assure you that the particular oil I'm using at the moment is completely natural and organic and does not contain any petroleum products or chemical pesticides whatsoever. I think there's a lot of misinformation out there about modern horticultural oils and that is the purpose of this discussion. I'm not trying to say that neem oil is dangerous, just that there are alternatives available which may be better suited for marijuana.

Most commercially available neem products list azadirachtin as their primary active ingredient. This neem component may not be as safe as you believe. According to Cornell University, "While considered relatively non-toxic, consumption of neem tree leaves caused mortality in guinea pigs and rabbits after 4 weeks of feeding trials.This extract also produced reversible infertility in rats and mice after 6 weeks of consumption. While fish toxicity is moderate and azadirachtin is not expected to cause fatality under normal use, accumulation may cause death if this extract is used for extended periods"

Sounds perfectly safe to me. I'll take a vegetable or soy extract instead, thank you.
