The Xylella annoying for a couple of years now has devastated one of the most significant items of the economy of Puglia. Are the same entrepreneurs who express concerns and suggest possible solutions
The ride of the Xylella fastidiosa: so George Greek, of which Ambient & Environments hosts photos and interventions, defines the path that led to the disease of trees of Salento (not just now, unfortunately); but he tells its battle won, as can be seen from the photos.
“I live in Salento, in the suburbs, and I feel clearly the shots; They are hunting days for fans, but not for long. Before long the thrushes and woodcock hunters will move elsewhere because here there will not be the forest of olive trees, the ideal place for wintering of these migratory species.
Even this aspect leads me to think that what is happening here will touch everyone, absolutely everyone. It will not be the supermarket of oil to fill the oil gap of unique quality product from our grandparents, for centuries; there will be little the superintensive rows to replace the Salento landscape reduced to a pile of firewood.
The settlement of the Queensland farm that tested positive for Panama Disease Tropical race 4 (TR4) will now proceed, following the confirmation that a suspect plant from a nearby property does not contain the disease.
The planned buyout of the TR4 farm, owned by the Robson family, was temporarily suspended late last month after the suspect plant was reported to Biosecurity Queensland (BQ).
The Australian Banana Growers’ Council (ABGC) is to buy the farm, after the country’s producers agreed to increase the industry levy.
‘Extensive diagnostic testing’ was conducted over the last three weeks on samples of the plant to eliminate any possibility of it containing TR4.
ABGC chairman Doug Phillips praised the Robson family and the owners of the other tested property for their patience during what he described as a ‘difficult and stressful time’ for all involved.
“The timing of the discovery of the suspect plant could not have come at a worse time as settlement of the purchase of the TR4 farm was due to proceed within days,” Phillips said.
Effective September 23, 2016, the Animal and Plant Health Inspection Service (APHIS) removed the Mexican fruit fly (Mexfly) quarantine in the Bayview area of Cameron County, Texas.
On May 27, 2016, APHIS established a Mexfly quarantine in Cameron County after confirming one Mexfly larva in Bayview, Texas. The quarantine restricted the interstate movement of regulated articles from that area to prevent the spread of the Mexfly to non-infested areas of the United States. Since that time, APHIS has worked cooperatively with the Texas Department of Agriculture and the Texas citrus industry to eradicate the transient Mexfly population using approved eradication protocols.
APHIS removed the quarantine area after three lifecycles passed without finding additional Mexflies in this area. The following designated website contains a description of the current federal fruit fly quarantine areas:
Eggs of an invasive mosquito species, _Aedes albopictus_, were
collected for the 1st time in September 2016 in the United Kingdom.
The species was confirmed on 30 Sep , using a variety of
morphological and molecular techniques. Despite extensive mosquito
trapping at UK sea and airports, imported tyre companies, and motorway
service stations close to the ferry ports and Eurotunnel, this is the
1st time that this species has been detected in the UK.
When Jon Eisenback, professor of plant nematology at Virginia Tech’s College of Agriculture and Life Sciences, conducted nematode surveys on vegetables and rice in Cambodia this past August, one of the most surprising things he encountered in the vegetable fields was, in a word, nothing.
“One of the biggest finds from that trip was almost completely sterile soil,” Eisenback said of the surveys he and postdoctoral associate Paulo Viera conducted in vegetable farms near Siem Reap.
They visited farms growing cucumbers, sweet melons, eggplants, tomatoes, and cantaloupes to assess whether any of them were suffering from nematode invasions, but they found that all the crops were grown under plastic with drip irrigation. They had been covered with so many pesticides that there was nearly nothing living – the soil was essentially ruined.
Plant parasitic nematodes are microscopic roundworms that cause significant damage to many crops. In Cambodia, a country with nearly half of its labor force in agriculture, nematodes can create big problems for food production.
EFSA’s plant health experts have reviewed new evidence regarding the categorisation of Vitis (grapevine), Citrus, Quercus ilex (holm oak) and Phoenix roebelenii (ornamental dwarf palm) as host plants of Xylella fastidiosa.
The X. fastidiosa bacterium has been present in southern Italy since 2013 and has subsequently been detected in Corsica and mainland France.
For six months, two banana plants grew undetected in a Darwin nature reserve, until they were stumbled upon by ABC staff on a weekend bushwalk and reported to the Banana Freckle Hotline.
The Holmes Jungle Nature Park, managed by the Northern Territory Parks and Wildlife Commission, is inside what is known as a red zone, where all bananas were supposed to have been removed in a bid to ensure any remnants of the fungal pathogen responsible for banana freckle would die out.
“Testing has shown the plants are free of banana freckle,” she said.
Ms D’Errico would not speculate about how the plants got into the reserve.
“From time to time we’re finding plants and it’s usually regrowth,” she said.
“It’s been a tiny number of addresses where we’ve found that plants are not being grown under authorisation, which means a permit. “Our fully-qualified inspectors are out there looking all the time. “It’s just an unfortunate occurrence that’s happened in that nature reserve.”

The Institute for National and International Plant Health of the Julius Kühn-Institut (JKI) has notified the first identification of a plant sample found positive to Xylella fastidiosa in the territory of Germany. During a baseline survey performed, on April 20, 2016 in a greenhouse of a small nursery producing young vegetable and ornamental plants, in Saxony, one potted oleander (Nerium oleander) plant showing suspicious symptoms was sampled.
