Cabildo de Tenerife and Government of the Canary Islands “work in a coordinated way” in the control of a focus of vine phylloxera located in the north of Tenerife
The Government of the Canary Islands and the Cabildo of Tenerife work “coordinated” to control a la la vid phylloxera focus (Daktulosphaira vitifoliae), which was detected at the end of July “in a vineyard in a private garden and in nearby partially abandoned land, in an area of Valle de Guerra, in the municipality of La Laguna”, The Canary Islands executive confirmed in a press release.
“With the aim of eradicating this harmful organism”, says the statement, “Both administrations established and applied phytosanitary measures to control the initial outbreak., including the removal of affected plants and their roots, and its disposal after disinfection”.
In parallel, “A delimited area was established around the detected focus, in which prospecting work has begun on all commercial and non-commercial vine plantations and will be carried out, consequently, phytosanitary actions aimed at eradicating this pest”.
In addition, Information meetings are being held with the wine sector of the island of Tenerife, “with the aim of offering producers the necessary information to identify this vine parasitic insect as soon as possible in the event that they have affected plants., with the purpose of being able to execute appropriate actions to eradicate it”.
These meetings “will be extended to all islands, so that if any farmer observes the symptoms that this organism presents on the plant, can immediately communicate it to the Agrarian Extension Agencies of the Cabildo de Tenerife or to the Ministry of Agriculture, Cattle raising, Fisheries and Food Sovereignty of the Government of the Canary Islands”.
In this sense, A technical document has been jointly prepared that is available on their web pages with information of interest for detection..
In addition, Next Wednesday a meeting is scheduled at the headquarters of the Canarian Executive department between representatives of both administrations, of Agricultural Professional Organizations, Regulatory Councils of the Protected Designations of Origin of Tenerife Wines and wineries on the island to address the evolution of the work aimed at controlling said focus.
The statement states that “This circumstance does not affect, in no case, to the quality and uniqueness of the wine made in the archipelago”.
What is phylloxera and how does it get??
the insect Phylloxera vastatrix, today called Daktulosphaira vitifoliae (Phyloxera de la Vid), It is a parasitic insect of the vine, first described by Asa Fitch in 1855, in the United States.
The damage caused by this harmful organism can be seen on the roots or leaves of the host plants..
On leaves it gives rise to the formation of galls caused by the bites of this insect that are visible on the underside of the leaves and correspond to chlorotic lesions visible on the upper surface..
At the root level, The presence of nodules and tuberosities linked to these bites is also observed in the rootlets..
If symptoms affect the main root, the vine will inevitably wilt within two to five years after infestation, causing his death.
The entry of the plague into Europe in 1863 caused a serious crisis in the wine sector, which was not recovered until three decades later, thanks to the use of American rootstocks that were resistant.
He arrived in Spain in 1878, mainly in three areas, Málaga, Gerona and the border area with Portugal, near the Douro river, the Canary Islands being free of the plague.
Currently it does not represent a phytosanitary problem in Europe, but it is a quarantine plague in those countries where it is not present, just like in the Canary Islands, that has its own phytosanitary status (Order of 12 March 1987).
In the Canary Islands to date, the phytosanitary status regarding Daktulosphaira vitifoliae is absent.
This consideration of the status for the Canary Islands has been maintained thanks to the validity of the Order of 12 March 1987, by which the phytosanitary regulations relating to imports are established for the Canary Islands, export and transit of plants and plant products that in its Annex III prohibits the import of vine plant material (Vine L.) except fruits and seeds, originating from all countries, including mainland Spain.
