Xyleta infecton in Europe from World Rose News December 2018

Please note:

" CLASSIFICATION & REGISTRATION – Mr Alain Meilland spoke of his grave concerns of the Xyleta infecton in Europe which has destroyed thousands of olive trees. It had emerged that the infecton had spread to a foribunda rose on the island of Corsica. As a consequence, the European Regulatons for reserving movement of plants declared that all foribunda roses cannot be moved around Europe or other destnatons. He felt that an urgent soluton needed to be found. "

    That was interesting, thank you... I just read all of that pdf...

    I best not try order floribundas from Europe, so it's good to read they are putting a block on them being transported across countries..

    Also welcome is that Hybrid Musks and Hybrid Rugosas are now going to be considered in the 'Old Rose' class...

    Dear Marlorena-z8

    Please find a correction of Mr. Alain Meilland, his comments have been misunderstood:

    During an analysis in 2015 in Corsica, 1 plant of “Rosa x floribunda” was found positive to the bacteria Xylella fastidiosa. After a second check, it appeared that the plant analyzed was not from the genius Rosa, it was a mistake. Rosa x floribunda has been removed from the list of the EUROPEAN COMMISSION DATABASE OF HOST PLANTS FOUND TO BE SUSCEPTIBLE TO XYLELLA FASTIDIOSA. From what we know, up to now, no sample of the genius Rosa has been found positive to Xylella fastidiosa in France or in Europe. Any plant of roses can be moved within European Union if they have an European Phytosanitary Passport, and outside European Union depending on specific Phytosanitary legislations of each country.

    Do not hesitate to ask if you have any question.

    Can you give us a reference for your statement?

    My interpretation of the link link below is that it has been found in 9 rose plants. (Please note that in the rose hybridizing thread it has been pointed out that this interpretation is incorrect.) http://rosebreeders.org/forum/viewtopic.php?f=2&t=56162

    Title: "Plant Hosts of Xylella fastidiosa In and Near Southern California Vineyards"

    Also, please see:

    Title: "Can Rose Plants Host Xylella fastidiosa?"



    This is what a Google search found:

    https://www.google.com/search?num=100&n ... 35&bih=516

    There is a reference to an infected Laurier rose (which is not a rose). Is this the cause for the confusion?

    H.Kuska comment:

    Rosa canina L. is listed in the last three updates of:


    XYLELLA FASTIDIOSA IN THE UNION TERRITORY – UPDATE 9, 10, and 11" They were updated on July 28, 2017, Feb 15, 2018, and Sept 19, 2018 respectively


    In the Dec 21, 2015 update (labeled update 1) Rose floribunda Steven (syn Rosa multiflora Thumb) was listed.

    In updates 2 through 8 rosa X floribunda was listed. These updates were Feb 3, 2016; April 18, 2016; May 30, 2016: June 27, 2016; July 15, 2016; Nov 11, 2016; and Jan 11, 2017 respectively.

    Is it possible that the original assignment of a floribunda was changed to rosa canina L. between updates 8 and 9? Or is it just a coincidence that one rose was removed and another separate rose was found in the same time interval?
