I found a vintage spray can of no seed blossom set from the 1960's in the garage and wondered if any modern sprays use the same ingredient.
Used on tomatoes and strawberries.Originally from the science products company in chicago.Active ingredient .0042%

Here's a Google search about that compound and still being used these days as a plant growth regulator. And made and distributed by several different companies.

the google searches only came up with the powder version.

I searched for a while and the only sprays I can find marketed towards consumers were based on kinetin, which is part of the cytokinin group of hormones. Hard to find scientific papers on cytokinin inducing parthenocarpy (fruit set without pollination) so i dont know why it is being sold now instead of the synthetic auxins like BNOA. Maybe because they can market it as a “natural plant hormone”? I saw 4-CPA referenced a lot as a synthetic auxin used for fruit set in greenhouses when temperatures are too low for reliable pollination. BNOA was referenced a few times, as was 2,4-D. Nowadays it seems the main uses of 2-naphthoxyacetic acid and 1-napthaleneacitic acid are in rooting hormone compounds and tissue culture media. Sigma-aldrich has several forms of 1-naphthaleneacetic acid listed for sale, but only one form of 2-naphthoxyacetic acid. My guess is that some of the other synthetic auxins are cheaper to make, are more effective, longer shelf life, have broader application, are easier to mix, or some other advantages.

When I'm not sure about a product, compound,whatever,I ASAP go to EXTOXNET, a superb resource.

And here's my search for Beta-Naphthoxyacetic acid.

Here's the homepage and note that it's a cooperative of several universites

And here's my search for this beta product

I know what I posted was difficult to read, but it's been a few years since I went there and the whole format has changed.

Checking my faves I found links to chlorothalinol ( Daconil),Maneb,Rotenone and Zineb.

I didn't read any of that long list I posted,maybe I should read a few of them, since what has been presented in the past has been where a product is made,who distributes it, what toxicity level it is rated at,etc.

Nothing is out of date for any of the ones I mentioned above.

And if I do a Google search for Daconil, here's what I get

You could do the same kind of searches I did for your Beta one
and probably do a better job than I did trying to answer your question initially.
