Ħabib tiegħi poġġa l-ħolqa fuq il-facebook ta’ artiklu li deher fuq in-Newsbook dwar susa perikoluża, għatba ‘l bogħod minn Malta, li qed teqred is-siġar tal-ħarrub,

Skont Newsbook, id-Direttorat għas-Saħħa tal-Pjanti qal fi stqarrija li s-susa bl-isem xjentifiku ta’ Xylosandrus compactus ġiet innutata f’Ragusa Sqallija fir-rebbiegħa tas-sena l-oħra, fejn qerdet ħafna friegħi mis-siġra tal-ħarruba.

Filwaqt li l-awtoritajiet Taljani nedew miżuri sabiex dan l-insett jiġi kkontrollat, dan infirex matul is-sajf u l-ħarifa.

Id-Direttorat bħalissa jinsab għaddej b’kollaborazzjoni mal-Università sabiex jiġbor aktar dettalji u jkun armat jekk din il-ħanfusa titfaċċa Malta. Sa issa għadhom ma ġewx rappurtati każi ta’ dan l-insett f’Malta.

Il-kobor ta’ dan l-insett ivarja bejn il-1.4mm u l-1.9mm, u għandu forma kemxejn tonda u ċilindrika, u huwa ta’ lewn kannelli jew sewdieni.

Il-vittmi ta’ dan l-insett bosta drabi huma siġar u arbuxelli li jkunu diġa ddgħajfu minn qabel, iżda ġew rappurtati każi ta’ siġar friski li nqerdu mis-susa.

Id-Direttorat irrimarka li din hija waħda mill-ftit susi li jinfestaw u jeqirdu pjanti b’saħħithom, u tappartjeni għal familja ta’ susa li hi differenti mill-familji l-oħra minħabba l-mod kif tħaffer fiz-zokk.

Christian Borg fuq il-facebook kiteb hekk:

“Id-Direttorat bħalissa jinsab għaddej b’kollaborazzjoni mal-Università sabiex jiġbor aktar dettalji u jkun armat jekk din il-ħanfusa titfaċċa Malta. Sa issa għadhom ma ġewx rappurtati każi ta’ dan l-insett f’Malta.”

Tajjeb li jsiru studji, imma f’dak l-istadju ma jidrilniex li jkun daqxejn tard wisq?? Espert zgur li minix, imma cert li jistghu jittiehdu iktar mizuri biex nevitaw milli jidhol dan l-insett.

X’tahseb Alfred E. Baldacchino?!

———-0———-

Nirringrazzja lil Christian Borg li ġibidli l-attenzjoni u staqsini x’naħseb.

Xi tridni naħseb Christian? In-nies ta’ dan il-pajjiż jidhru determinati li jagħmluh deżert mingħajr ebda siġra. Naraw l-importazzjoni ta’ speċi invażivi bl-addoċċ u mingħajr kontrol, xi kultant ukoll imħallsa minn flus pubbliċi; nfiq ta’ €57 miljun minn flus pubbliċi u tal-EU wkoll biex l-ilma tax-xita narmuh il-baħar, waqt li dak tal-pjan jitella’ kif ġie ġie, bla kontrol ta’ xejn. Meta ħadd ma għandu l-ebda ħjiel, jew xi xewqa li jkun jaf bid-diżastru li qed inġubu fuqna, anzi nonfqu l-flus biex inġubuh b’idejna, x’tistenna?

Mill-esperjenza li għandi ta’ dan il-pajjiż, issa nistennew u nitolbu biex din is-susa ma ssibx ruħha hawn Malta. U meta tidħol imbagħad ngħidu li daħlet u nibku ftit ukoll u ngħidu ara x’ġaralna! Imbagħad inwaqqfu l-importazzjoni ta’ dawk is-siġar li din is-susa tista’ tiġi magħhom. Jew inkella nivvintaw xi bexx biex inbigħuh lil dawk li għandhom xi siġra tal-ħarrub biex inkomplu ngħinu lil dawk li l-għan tagħhom huwa li jagħmlu l-qliegħ mill-injuranza ta’ dawk li jmexxu.

Din il-ħanfusa hija indiġena għall-pajjiżi mill-orient, u nfirxet permezz tal-kummerċ. Hija tattakka madwar 200 speċi ta’ pjanta.
U jekk tgħidli li qed nesaġera, infakkret f’meta daħal il-Bumunqar Aħmar tal-Palm – ir-red palm weevil. Minkejja li kien hemm pariri biex ma jiġux importati siġar tal-palm minħabba dan il-bumunqar, xorta ġew importati. U minn fejn? Minn dawk il-pajjiżi fejn dan kien qed jagħmel ħerba bla rażan. Sallum inqerdu ‘l fuq minn 5000 siġra tal-palm.
U hekk naħseb li sejjer jiġri minn dan il-susa sewda tal-friegħi (black twig borer).
Ir-responsabbiltà biex jittieħdu passi hija tal-ERA – l-Awtorità tal-Ambjent u tar-Riżorsi). Din għanda l-għodda legali kollha biex twaqqaf id-dħul ta’ din il-ħanfusa. U magħha hemm ukoll is-Segretarjat tal-Agrikultura. Dawn it-tnejn qegħdin fil-Ministeru tal-Ambjent.
Issemma wkoll li “Id-Direttorat bħalissa jinsab għaddej b’kollaborazzjoni mal-Università sabiex jiġbor aktar dettalji u jkun armat jekk din il-ħanfusa titfaċċa Malta. Sa issa għadhom ma ġewx rappurtati każi ta’ dan l-insett f’Malta.”
Dan jgħati ‘l wieħed x’jifhem li d-Direttorat diġa qata’ qalbu li jwaqqaf id-dħul ta’ din il-ħanfusa f’pajjiżna, u qed jagħmel studju biex jikkontrollaha meta tidħol. Imma ma hemm l-ebda viżjoni, ħeġġa jew determinazzjoni biex din il-ħanfusa ma titħallhiex tidħol. L-istess kif ġara meta daħal il-Bumunqar Aħmar tal-Palm.
U ngħid jien, meta l-Università ħallset biex 60 siġra taż-żebbuġ inħasdu metru ‘l fuq mill-art, għax kif intqal kienu qed iwaqqgħu ftit weraq fuq il-karozzi, u qisu ma ġara xejn, taħseb li l-Università ta’ Malta, għandha xi viżjoni, ħeġġa jew interess fil-ħarsien tas-siġar u kif sejra titwaqqaf din is-susa sewda tal-friegħi milli tidħol hawn Malta?
Kull ma nista’ nagħmel jien, Christian, huwa li nitlob ‘l Alla biex jgħinna ftit ħalli nużaw imqar niskata intelliġenza minn dak li tagħna, forsi nbexxqu ftit għajnejna mill-għamad tal-kilba tal-flus li qed jaħkimna, jagħmina u li sejjer jeqridna.

Olive Quick Decline Syndrome

Olive Quick Decline Syndrome

Alfred E Baldacchino

Mid-October 2013, saw Xylella fastidiosa, the olive quick decline syndrome (OQDS) recorded in Italy: its first record for Europe. By April 2015 it had infected up to a million olive trees, many of them century-old, in the southern region of Apulia. This invasive disease is believed to have been introduced by ornamental plants from Costa Rica, where it is also causing havoc.

By July 2015 it quickly spread to Corsica, in municipalities of Nice, and Mandelieu-la-Napoule and by late October in Alpes-Maritimes in France. August 2016 saw it in Germany infecting oleander plants.

November 2016 found OQDS in the Spanish island of Mallorca, in a garden centre on three cherry trees and an oleander.

OQDS is regarded as the most harmful plant pathogenic bacteria in the world. It infects grapevines, peaches, citrus, oak, sycamore, and many other trees and ornamental plants, such as spurge, lavender and rosemary. No cure has yet been found for such disease, as the European Food Safety Organisation has warned.

European and Mediterranean Plant Protection Organisation (EPPO) had since 1981 listed it on its A1 list of pests recommended for regulation as quarantine pests, regarding it as representing a very serious threat for the EPPO region

Symptoms of OQDS, regarded as the most harmful plant pathogenic bacteria in the world.

Across Europe, 359 plant species have been identified as susceptible to Xylella. Many of these species show no symptoms of the disease, and provide a reservoir for reinfection of other plants, thus making Xylella difficult to control and making phytosanitary certificates  useless

This bacterium thrives in the water-conducting vessels (xylem) of plants. It invades these vessels and blocks the transport of water and other soluble mineral nutrients. This leads to the drying, scorching, wilting of the foliage, and eventually the collapse and death of the tree.

Spittlebugs – serves as carriers of OQDS

It spreads with the help of insects such as leafhoppers and spittlebugs, which feed on the plant xylem. These insects do not fly long distances, but can be helped by the wind, by other animals, and by vehicular transport.

Spain and France were deeply concerned when Xylella was recorded for the first time in 2013. Their production of olive oil and wine is under a great threat. The matter was also raised at European Union level.

Italy is heavily affected, considering that the only method to date to control such disease is by eradication of the infected million olive trees. These contribute to 40 per cent of the olive oil produced in Italy. Besides the economic loss, the social and ecological impacts are beyond any estimate.

Olive trees which succumbed to OQDS. Not that we really need Xylella to reduce our olive trees to such a state. The sight of the 60 olive trees on Malta University campus were similarly aesthetically reduced and paid for by University funds. Perhaps the University’s educational pro-active vision wanted to show the people a picture of things to come if Xylella succeeds in being imported in Malta. The only difference would be that they will give up their  ghost for ever.  

Malta is blessed that it is an island surrounded by an expanse of sea that makes it impossible for these xylem-feeding insects to arrive naturally. But… it seems that we never learn.

Pruned olive trees which once enhanced the campus of the University of Malta. A mis-management exercise of the highest grade.

Palm trees were imported for landscaping purposes from areas known to be infected by the Asian red palm weevil. More than 5,000 palm trees have been lost to date. Timber introduced the African long-horned mulberry beetle, which besides killing most of the mulberry trees in the islands, now has turned its attention to the white mulberry, carob and fig tree.

Imported geraniums by garden centres have also helped to introduce the geranium bronze butterfly from South Africa. All of these have been introduced by trees and plants carrying a phytosanitary certificate from the country of origin, to confirm that they were all disease free. How many imported tomato seedlings accompanied by a phytosanitary certificate, introduced the South American tomato moth (Tuta absoluta)?

Trees and other plants mainly, for landscaping and ornamental purposes, are still being imported from countries which are infected with this OQDS.

The Ministry for the Environment is responsible to ensure that such invasive species and other pathogens are not introduced in Malta, both through the Environment and Resource Authority, and also through its Parliamentary Secretary responsible for the Department of Agriculture. Once there was a renowned experimental farm at Għammieri, which today is more concerned with domestic dogs, cats, and birds.

A very good animation video has been produced by the Plant Health Department. Very good. What is needed now is urgent action.

Environmental responsibilities are far from being helped by the Ministry of Landscaping. Doors are flung wide open for exotic species to be planted in ‘landscaping’ projects, paid out of public funds, administered through an €8 million yearly budget, according to a secret agreement which, despite the Commissioner for Data Protection’s ruling, is still being withheld.

If Xylella were to make a foothold on this island, the price that society and the environment will have to pay is beyond any imagination

Those handful of pro-business politicians and their acolytes might ask if they are expected to stop the importation of exotic species. The question is whether such politicians are worried, not only for the young developing olive oil industry in Malta which is trying hard to acquire an EU/EC Declaration of Conformity (DOC) for CE Marking, but also for the wine and citrus industry. And naturally the islands ecosystem which if, God forbid, Xylella were to make a foothold on this island, the price that society and the environment will have to pay is beyond any imagination.

Prevention is better than cure, especially when there is no cure at all. That would be the day when one can honestly boast of a sound environmental policy. From experience, political action in this regard will only be considered when the social, economic and environmental fabric have bit the dust, or as it is said, when all the horses have bolted.
