An alternative would also be nice... maybe test apples as last resort?
All I found out was that approved farmers can get it (e.g. Florel) litre-wise. Find one and ask if you could get some millilitres. Where I live, no one uses it (or at least nobody admits using it).
Where I live, Florel brand ethephon 3.9% concentrate ("Fruit Eliminator") is available off the shelf at the local farmers feed store (as well as nurseries/garden centers) @ about $10 for 8 fl oz (236 ml)... just picked up some more just the other week...
I'm no farmer, per se, and I sure as heck ain't 'approved' by anyone...
