I know they mostly sell organic products which is why I looked at them, but they don’t say what the main ingredient is! Might be worth a try, though, for those who want an organic option.
Also, found this available as a quart for $20. Says it contains saponins (soap-like chemicals from plants) from the yucca plant and is OMRI certified. Not many reviews, it the few I can find are positive. I think I might give that a shot with its comparatively lower price point and smaller size compared to something like nu-film.
If you want a pint of Nufilm just PM me, I have a full gallon of it now (just finished the first gallon, ten years after buying). I owe you one anyway after that neem disaster on your apple trunks!
Hey Scott, thanks for the offer. Don’t feel bad about the neem - it was something that worked for you and others, and most advice doesn’t come with a warranty! It is great to have a place to share information like this about both positive and negative results.
As far as I know, the akyl aryl polyethoxylates it can’t be organic because they are synthetic compounds. I have no idea what they use in the EU. It might just be that specific classes or compounds are restricted there. The nonylphenol ethoxylates (one is used as a spermicide) were the major ones I found that are likely restricted in Europe and generally have been removed from products in the US.
Nu Film and Pinene II (generic NuFilm, I gather) products are some sort of polymerized extract of pine resin.
Bonide’s Wilt-Stop product and Pinene II have exactly the same Chemical Abstracts Service (CAS) number in their MSDS, which is generally given to a specific chemical. They are likely to be the same product. This is consistent with the fact that Bonide essentially mixes and resells other products as RTU and home-use concentrations. Some of Bonide’s labels say “includes X product” e.g. Cueva (Cu-soap) or Pristine fungicide.
I submit that if you want to use Nu Film/Pinene as a spreader-sticker, you could buy Bonide Wilt-Stop concentrate and use 4 tsp for every 1 tsp of Nu Film 17 specified (Wilt-Stop concentrate is 25% AI).
