fig problem

What type of disease would you say this is? it's been humid and rainy here in Pa. This Black Mission is the only one with this problem.
There's a sticky substance on the skin. It's probably from the sap, but not sure.
..

Back in the old neighborhood i had a neighbor with a pear tree and the bee's used to sting the fruit it looked just like your fruit minus the white stuff though.

Martin you could be on to something. Since the figs are immature the stings would result in milky white latex right.

I can only testify for the 'white' stuff. I had reported my earlier
obeservation last year. The general consensus was that it is
just latex oozing out, most probably due to overwatering and/or
excessive rain (which right now; the whole NE is getting).

Bass, have you cut into the fig to see if there is something going on inside the fig. It seems to have a bruise or something at each area of white stuff. Perhaps it's insects damaging the skin causing it to leak and then again with the cold wet summer you've had, perhaps the fruit is starting to rot before it ripens. Just my untrained thoughts.


Looks like two issues; 1) the white stuff and 2) the bruising/scaring/brown spots.

1) Celeste sometimes has something like the white stuff which oozes from the skin, but is usually clear to light amber in color, and I have always assumed it was sugars that seeped through the skin. Since these figs are not ripe, the same effect would give you latex/sap rather than sugar.

2) The dark spots/areas look more like bruising from hail, bugs, or whatever, unless the figs are deformed and/or have some internal issue which is working its way out. I would agree that cutting one of those in half, particularly through the middle of a spot whould be most enlightening when trying to decide if it is an inside to outside problem or vice versa.

Thanks for your comments. It does seem to be the sap oozing out. The black spots can be the rain we've been having. It could be this variety is more affected than others, none of my other trees have that problem.
I tried to email the folks at UCdavis but got an invalid email. Jon who would you contact?

Actually, Louise Ferguson at the Kearny Ag Station in Parlier might be a better resource.

Bass, I found a few figs from 2 variants exhibiting similar issues. The 2 affected variants are : Malta & Marseillies VS. Others are not affected plus weather  was hot.


 Latex ooze spots.. Yellow Jackets sometimes feed on my figs. If not sweet /ripe enough , they do not eat further. But, first bites cause ooze. Also, some beetles bore in on fruits(see the dark spots) and again ooze.
  But, that is only my observation, sure could be other factors/reasons.

I've had a similar issue on my 'Celeste' figs in years past.  It usually shows up after a heavy rain and just before the leave show evidence of Rust.  I always assumed it was either a blight or a fungal disease similar to (or even the same as) the one that causes Leaf Rust brought on by excess humidity.  The white stuff may be some sort of excrement of the fungus.

blood/sap from oozing.

Upon thinking about it some more,  'Celeste' did this a few times.  'Kadota', 'Alma' and some other green varieties were more susceptible to the issue.  The issues are the black spots.  I do not remember seeing anything resembling the white spots before.

Hi Bass,

 How did you make out with this issue?

Geo

I haven't received an answer from UCDavis or Kearney, so I did my own research. These spots are called necrotic spots, they are caused by " Long, flexuous, rod-shaped, virus-like particles known as LFP" it is very similar to Mosaic Virus. 

If you want to read more on it, there's a study done on Mosaic virus in Turkey the top producing fig country.

Bass, 

It looks like you got to the bottom of what was going on with your figs. It's interesting how similar your fruit looked to the ones pictured in that info.

I didn't read the entire file Bass but did you ever get find a reccommendation for a treatment? Is there one? I hope I never have to deal with this but it would be nice to know what to do just in case. 

Hi Bass have a couple questions about your plant and the necrotic spots displaying in your plants figs.

Did you see the same thing on same plant in 2010
Did those figs drop ? 
Are you seeing the same thing on same plant this year as well.

I have not seen those spots shown in the link picture D on my plants yet.

But i report last season the FMV display on the figs shown in that link
picture  "B" on my Pastiliere and this season 2 other types that are young plants and displaying figs for the first time showing FMV on the figs just like the leaves.

I'll have to watch them this season and next season then decide if they need to be destroyed.

The Black spots are Fig mosaic virus on fruits.
Some infected trees show only ,on leaves,FMV,other,(only a few cultivars),show the FMV,on fruits too.
Of course the white spots are sap oozing out,trough Damaged skin,as results of illness.


 

if they do ripe, are they safe to eat?

Bass, thanks for the link.  It is interesting in that the authors use the term "Fig Mosaic Disease" (FMD) instead of FMV.  They point out the different leaf and fruit symptoms have different Disease Associated Bodies, some viral and possibly some bacterial (phytoplasma).  They are still uncertain as to the etiology.

I realize this is a very old thread. However, I'm experiencing this exact problem. One of my trees - a Marseilles Black VS - has figs exactly like bass' old pictures. Some say it's from bees. Others from FMV. Not sure which to listen to. So I have 2 questions. 1st, can I eat them? 2nd, is there anything to do with a tree that has FMV to help it? Might sound like a basic question. But until I joined this forum I wasn't aware of FMV. Thanks..Tony

I get black marks on figs when they are close to leaves, the rubbing from leaves in the wind etc causes this as well.  The sap swelling is either as Herman says from infected fifs leaking out their pores or as someone else said, overwatering and creating root pressure that forces sap to come out in my opinion.

Are these the same white crystals? I have no idea what they are. its kinda hard to scrape off and its hard like a grain of sand.  Anyone know what these are?  Some kind of insect poop?  They seem to be above the veins in the leaf.


All of my plants are under the same growing conditions and they are only on my MBVS.

Any ideas on what they are?


David, I have seen this on some of my plants, I believe it is fig latex from probably an insect bite. Doesn't seem to be a problem, and probably sends the insect on it's way. Could also be little tears from fast growth or wind or something like that.

Thanks Mike, I was really scared that those crystals were some adverse reaction to over fertilizing or something.
