Is this FMV?

Was watering my neighbor's fig and saw that a couple leaves looked like this. Is it FMV? Or is that normal when the leaves are so new? And if so, is there anything we can do about it? Oh, and does it look like a brown turkey leaf? :)

From this one leaf it appears to be a mild case of FMV.

Collectors like myself are not bothered by it.
But there are others that don't want to deal with. 

Jon of Ecanto told us that FMV is transferred by mites, at the Fig Fiesta 2013 in San Diego.

From what I've read, that's the belief...wonder if they ever confirmed that however?

Is there a way from preventing it from getting worse? Or a way to treat it? And does this mean my trees might get it too? Sounds like it's not the end of the world, but if I can do something about it now I'd like to try.

If you have it already it is relatively difficult to get rid of.

But if you are one of the luck few to find those FMV free cultivars which are out there you will need to keep the infected plants away from the ones that are not infected.

One of the good ways to prevent an infection on a healthy specimen is to clean your tools. Such as your pruners, saws, shovels and even your used pots. Anything associated with the cultivation of figs.

You basically have to make your own quarantine for the healthy figs.

One infected plant could infect the others near by. Not saying it will but there is a great possibility.

If this is a concern to you I would suggest to research it and learn and get to know about it.
Or you can just say to heck with it and deal with it and move on.

Good luck.


Yes.

An established tree is not usually bothered much by FMV.  Taking a cutting from that tree might show more signs of FMV when it starts growing, but eventually will overcome it.  Some trees are so heavily infected with FMV, that a new cutting would grow very grotesquely until it establishes itself.

I have a Red Sicilian that looks like it belongs in a horror movie.  The lower leaves are all misshapen and disfigured, but the upper leaves are starting to look better.  I don't know if that's common for that cultivar, or i just have a bad strain.

Interesting. So if my seedling that i have was from that tree, would it also be infected? ie would it be in the seeds too?

jujigirl, it really doesn't matter in a Mediterranean climate.  Your fig will thrive and produce with or without FMV.  It seems to matter more in colder climates, or those not so ideal.  Almost all figs have it.

Welcome to LA, Cali... the land of FMV, all my last years rootings are developing MV slowly yet steadily...ugh. oh well.

Since we are at it... Can I protect my New Blood lines from Italy and Cyprus? I haven't root them yet and they are from the original land ;)

that one leaf doesn't show much but other are also infected , so its everywhere. I have few growing with just half inch patch here and there but i already consider them infected so they will be in separate part of my backyard from my newer bloodlines from Italy and Cyprus.

LA is a fig paradise. FMV won't make much difference. FMV is a viral disease. it won't go away, and there is no cure. seedling might have a chance of not having it, but since there are so many fig trees around that area, chances are pretty good it will get it sooner or later.

really, FMV won't make much of a difference. chances are pretty good you won't notice it as the season moves along.

Aaron, FMV is endemic in the Mediterranean world, your varieties from Italy and Cyprus likely have it already, unfortunately

ahh, ok, then I'll just live to accept and enjoy figs with it. what else is there to do, I mean...I'm not pro chemicals to begin with and seems like there is no point of bombarding the plants with chemicals for something that will come back no matter what. Specially with Caprification and all... the cure won't last long ;/

Aaron,

My opinion is based solely on that one leaf. I understand the rest of the tree will have it or might have it.
It is a very mild case.

But then again it can be just that one leaf or just that one branch of the tree that is effected.

I have a few trees that display this behavior. I can't explain it nor do I understand it.
But most of all it does not bother me.


thanks for the input Rafed.

Doug, these patches come in different forms, it definitely is not Leaf Miners.

Next time I go over there I'll check the leaves more closely. We have leaf miners on some of our citrus, so it's certainly possible. THANKFULLY I will hopefully not have to water there the rest of this week - we might get rain today! And friday!!!!i'm so happy. Though now I'll worry that my fig in the container is going to get TOO wet, lol. It's always something.

Jujigirl,
Attached are pictures of Leaves symptomatic of Fig Mosaic Disease. Its very easy to tell by "back lighting" the leaf.

The pale areas are actually thinner that the surrounding leaf.


document by University of Agriculture in Turkey  linked in several FMV topics on this forum,

It was previously reported that FMD can be transmitted by vegetative propagation material and an eriophyd mite, A. ficus (Flock and Wallace, 1955), but not by seeds (Martelli et al., 1993). In this case, FMD must have been transmitted into these seedlings by eriophyd mites. In our ongoing studies, this mite transmits FMD agents into healthy fig seedlings (Çağlayan et al., unpublished data).

, a document by UC Davis which is linked in the FAQ Glossary under Fig Mosaic Virus,

COMMENTS ON THE DISEASE
Black Mission is the most seriously damaged cultivar; Kadota and Calimyrna are the least affected. Ficus palmata, or trees derived from seedlings having F. palmata as the male parent, appear to be immune to mosaic. The fig mosaic is vectored by the eriophyid mite Aceria fici; feeding by a single mite is sufficient to transmit the virus to a healthy seedling of F. carica. The virus can also be transmitted by grafting, but it is not seed borne.

and a more detailed UC Davis article on Fig Mites and Virus transmittal (Flock and Wallace, 1955)

If you are pushing the envelope, and growing figs where they don't naturally grow, FMV can be an issue.  It is NOT an issue for Jujigirl!  She lives in Fig country, and her figs will thrive with or without FMV

But I have learned from this forum that FMV affects fruit and growth in places where figs are not native.

We all have zone envy.  I wish I could grow cherries.  Ha!  Pipe dream!  But figs thrive here as they do in Jujigirl's zone. 

The good thing about those in zones 2-8 with figs is, you can do the fig shuffle.  You can have a greenhouse. 

But how do you create 400 - 900 hours of chill when you have less than 100?

I guess if we northerners can spend > $1,000 on a greenhouse to keep our plants warm or extend the season, you warm weather folks could spend <$100 on a used refrigerator and stuff your potted fruit tree in it one at a time for a week to give them chill hours?   
j/k  :) 

One thing about growing up is the knowledge to know your limits! 

Not going to stuff potted cherry trees into a fridge!  I'll just happily go to the grocery and BUY the cherries, BUT a fresh fig from your own tree is different than one bought at the grocery.  Don't think there is much difference in cherries.  Is there? 

Do your fig shuffle!  Enjoy your fresh figs!

I have got to say, I have 2 Anna apple trees here.  They like low chill.  They were bred in Israel for heat, and those apples are better than any I've ever tasted at the grocery.  JD is not an apple lover, but he got swayed.  We are thrilled to have the Anna Apple. 

You just have to buy the fruit trees that do best in your zone.  Don't fight it!

Suzi

haha! The electric company already owns me, add another fridge and it would be cheaper for me to just buy another property somewhere with more chill hours. ;) But really, I was just celebrating yesterday b/c I can see baby apricots and white nectarines forming on my trees...I was worried my trees might have taken a vacation this year, with how wonky our weather has been. But yay, there they are!

Actually, the damage from mites on bottom side of leaf will ALSO cause the discoloration elsewhere on the leaf..
I have seen it on one or more of the 45 fig trees I have growing in the ground.
Ask anyone with experience.
I've farmed for over 20 years. It gives you hands on experience.

There are soooooo many reasons for discoloration in corn, soybean and many other crops.
Figs too I'm learning.
FMV is a catch all for under experienced growers with dis coloring leaf problems.


Again IN mY Opinon, yours will vary.

Doug
Haha, Doug, point taken. So, you actually gave us a positive input about FMV. And... no, I would never have disregard on someone's 20+year experience, I am not THAT ignorant;)
Thanks for your input on the subject Doug.
