Fruit disease

21 years ago

My Calamondin tree and one of the Persian Limes are having a problem on their fruit. The bottom of the fruit (blossom end) gets a sunken, leathery, tan appearance and the fruit colors up quickly and starts to decay at the lesion. The fruit go from perfectly normal looking to diseased very rapidly. It does not affect all the fruit. One tree is in the ground, one is in a half whiskey barrel. Both produced normal fruit last year. Foliage is normal. It has been very dry here, no rain in over a week. I water the potted tree, but not the inground one. The fruit does not touch the ground, in fact most affected fruits are high up, in clusters with healthy looking fruit.

I've been looking online at fruit diseases but haven't found one yet that looks like this.

Ideas?

Thanks!

    Lisa, I can't help you w/your problem, but I've a question. I know government inspectors check trees (in Fl) for Canker and Green disease..Do they also inspect trees of people who do not sell citrus? If they do come out and find one of these diseases on plants, do they burn the trees? Toni

    Toni, if you are asking if the State inspects dooryard/potted/indoor citrus owned by regular folks for canker, the answer is yes. You do not have to be a grower/nursery/dealer to be inspected. They can supposedly come on *anyone's* property to check and see if they have citrus. And yes, they will cut, remove and destroy all citrus trees within a wide radius of a canker infected tree, no matter who the owner/s are.

    If someone in my neighborhood has a citrus with canker, and it is discovered, the state can take all my healthy trees.

    For the loss of my trees I would get a voucher for WalMart- a store I detest. So, I branched out and got lots of non-citrus tropical fruit trees to soften the blow, if it comes.

    They cannot take non-citrus trees. They also cannot get on my property without someone being home(G).

    It is so sad to consider that citrus may end up only being grown as indoor plants in cold climates. I have NO faith that the Government efforts will do any good.

    Lisa, guess I understand their reasoning, but to have someone come in and destroy my plants.........grrrr
    What's your opinion about the government doing this?
    Why Walmart? The least they could do is refund people the full price of the tree..at least those in pots..I don't know how they'd determine one growing in the ground.
    Is this setback going to increase citrus in stores? Juice, fruit,etc? Toni

    Toni - You may understand their reasoning, but I certainly don't. Florida Citrus Nazis have been arbitrarily removing dooryard trees for a few years -- but what has it accomplished, aside from an overcrowded court docket?!?

    Lisa, there is a Stylar-End Rot that I know attacks Limes such as Tahiti. I really do not know if it attacks Persian Limes. Here are the symptoms. (ref. the Compendium of Citrus Diseases.) "Stylar-end rot breakdown begins as a water-soaked, tan lesion at the stylar end of the fruit. It progresses very rapidly and may eventually cover half of the fruit surface. The affected area later dries, contracts, and becomes sunken. Stylar-end rot appears particularly if rainy weather is followed by high temperatures. I hope this helps. Take care. I totally agree with you 100% concerning wall mart. (I will not spell the name using capital letters) - Millet

    AAE, I didn't say I agree with it, uh, uh. But, I guess if someone's trees can start an epidemic, maybe there's some importance. I sure wouldn't want someone coming to my house, burning my plants. I don't know, mixed feelings, I guess. Toni

    Millet, that description fits closely. We did have very heavy rains, then dryness with extreme heat.

    I'll research that disease, now that you have given me a starting point.

    Thank you!

    Toni - That's my point. There is NO reasoning, since they ARBITRARILY cut and destroy trees. They don't bother testing a tree for canker, ctv or anything else. They just remove it. Now... Do you still have mixed feelings?

  • 21 years ago

    Almost certainly stylar end breakdown. Remember that "Persian" is the marketing nickname for 'Tahiti', not a different variety.

    Lisa one of my Cal's had this problem last year. It is producing fine this year.

    Here is a similar problem with grapefruit :

    Thank you Malcolm Manners and Laaz! I was worried about it being a nutritional problem of some sort. I am having trouble finding any info on treatment-is there a treatment or preventative? I hate to see fruit wasted... I've been picking them and cutting off the bad parts of those mildly affected, and using them. Others have to be thrown away.

    Malcom Manners, of Course Tahiti = Persain. I never ever use the name Persain, and in Colorado rarely or never hear it, and did not recall. There you go Lisa, at least you know what is wrong with your tree. BTW..There is another Manners (a Mr. G. Manners) that works with the USDA and does a lot of citrus research with the University of Califorinia Riverside's Citrus Varietal Collection - Millet

    Interesting -- I don't know the other Manners, and there are not many of us in the U.S. -- maybe a long-lost cousin!
