These brown spots only appear on my Angelo's Dark, and my Scarlett Unknown which is a Mt Etna type fig! And it only is on 1 out of 15-20 figs! So I usually pull them off, but what is it what causes it, and when u touch a affected fig it feels gritty, see white spots on top brown spots in last photo, that's the gritty thing, it's feels like salt is on it! Very strange last year I let these ones ripen and they tasted exactly the same as the good ones! Really no problem with them just st ugly looking is all, but there has to be a technical name for it, and a cause! Please let me know!
Thanks

I don't know for sure, but it reminds me of the apple maggot tunnels.  I would check the inside to see if you can find some kind of larvae there.

I would also love to know what's causing this.  Almost all of the figs on my MBVS have this and maybe 25% on my Hardy Chicago.  I have about another dozen trees with figs that aren't impacted.

I would think a fungi/critter of some sort. Grit could be eggs or spores. 

Bust out the Neem, see if that helps.

Maggots! None of my Figs look like that?

Hi,
This is insect damage IMO .
I would lime the trunk (/paint the trunk with lime) as most insects doing such damage are crawling insects and they would be destroyed.
You could try to catch them and destroy them ... but they may well act during the night ...
The white spots are solidified sap that the fruit will bleed in an attempt to heal the wounds caused by the insects.
I would look for some kind of caterpillars .
Good luck !

It is caused by virus, mosaic spots in B, necrotic spots in D. The gritty stuff is resin or sap that leaks out and dries because the necrotic spots crack as the fig grows.

Did you spray all of your trees with the spinosad? btw, my cats get spinosad to keep fleas off of them and one of the pills has as much spinosad as you used in a gallon, so it seems pretty safe to me.

Aside from pruning and discarding (a new tree started from that part of the plant might have it on all its branches) the affected branches or starting new plants from growths that don't have the problem you will have to wait for the plant to grow out of it just like the leaf symptoms caused by FMV. I only remember seeing this on one tree before i had fig bud mites, then it was on lots, without the mites pruning seems to work OK though.

Another possibility is Thrips.  They target many types of plants.  They seem to prefer "hairy" figs such as Celeste, Hardy Chicago, Florea, etc., leaving multiple scars.  The do attack smooth figs also, but the damage usually isn't as severe.  When very small figs are damaged the fig can become deformed.  This is a picture of a fig that has been damaged.  The white speck on the top is oozing sap (that will dry to a brown scar).  The thrips is the very small insect above the eye, and for comparison, the small insect below the eye is a fruit fly.

This picture shows the brown scars left when the sap dries.  The damage can be much more extensive.
