If this LdA is misidentified and ends up being a Smyrna fig I guess you have a few options.
Besides getting rid of the tree or using it as a rootstock, I was thinking of how to get it to successfully bear fruit.
Artificially pollinating seems to much trial and error and not sure if you have a persistent caprifig.
On the other hand I was wondering about phytohormones, I know they are used commercially to increase fruit yield.
The linked article seems to indicate that it can be done to produce fruit without pollination but I'm not sure if it works with figs.
I'm probably missing something. Anyway here's the link.

Gibberellic acid, GA3 can be easily purchased. Not sure if Osborne's carries it but it but Amazon and Ebay sell it.
Oh, one last option, you can move to California and bring the tree with you. :)
 

Hey Kerry to all the figs have a long neck like that?

It sort of looks like hava wich baud has and is a Smyrna.
But if I'm Not mistaken it's got mostly single lobed leaves.

Nelson , They don't all have long necks like that , but many of them did this season.
They also tend to show clear ribbing on the surface.
Hava fruit does look pretty similar in general , but I don't think there are many single lobed leaves on this tree.

John , if you would like to try the gibberellic acid test come on by and I'll give you this tree !

I did live in Mendocino County for a few years and certainly wouldn't mind going back at some point.

Yesterday I stripped all but the largest fruit to see what happens.

My Melanzana looks very similar to the 1st LdA.    

Someone mentioned that LdA and Melanzana (long one) are very similar except that LdA ripens earlier and is sweeter? 

    

Anyone have an idea what the Longue D'Aout imposter is?  Mine drops main crop figs also.  They turn purplish and then drop.

i Have a melanzana from Bill's Figs that drops the main crop after they turn purple, someone suggested to prune the tree back soon after the Breba crop and eliminate the main crop so new branches can start for fallowing year Brebas. i just done that and unless i get a great Breba crop next year it's going in the dumpster

Mario 1- I tried that with my Bill's Melanzana. Even the brebas fell off. After several years of failed crops, I got rid of it.

Leon/Mario
Is your Melanzana from Bill's the round one as in Leon's earlier post? I see it called Melanzana Tonda (round) in Italy

The Melanzana I have is long and looks similar to LdA.  A 2nd year plant had delicious breba and has not dropped its 4 main crop figs.

Yes Pino my melanzana from Bill is round, the brebas were great, first crop all dropped, if I am successful on getting more brebas I will keep it

In my reading around threads in this forum, I have seen that:

Longue d'Aout = Slocan = Melanzana MS

And these are NOT just plain Melanzana. But now it appears there are different varieties of Melanzana from various different sources? 

I am trying to read about all kinds of different varieties to at least weed out varieties not worth trialling where I live. Now I am starting to understand everyone's comments about how confusing nomenclature is in this crazy fig world we live in! Maybe it would be easier to just try one of everything and if it doesn't work, pass it on to someone else. I have tons of patience, but some days it's more fun to grow things than wade through heaps of information. All praise to the persons dedicated to keeping things as clear and concise as possible!

I hope you find some more answers drivewayfarmer!

Seghen (luteo) good idea, but if it does'nt work for you don't pass it on, the dumpster may be a better place

 My fig cutting came as "Melanzana"  and was told it was a nice big fig and they got it from Italy.

LdA looks very similar to me in photos. 

The fig in the last 2 photos of post #18 finally ripened. The only fruit this Not Longue D'Aout tree has ever managed to ripen. It was pretty big at 90 grams.
Very good taste sweet ,but not too sweet , full of syrup and very refreshing.
Tasters gave it a 7.9 out of 10

      
The fig pictured in the 4th photo on the right side of the plate and at the bottom of the last photo is Fiorone di Ruvo , main crop not breba.
Looks almost identical but was larger at 115 grams , more syrup and richer, more full flavored. Tasters gave it 8.5 out of 10 with the .5 being added for size with great taste.
Leaf shape on the Fiorone di Ruvo :

  The growth habit of FDR plant is more spreading even a little droopy while the Not L D'Aout is very upright.
