Scientists have identified four new pathogens previously not found in Australian chillies, raising the stakes for the country's quarantine and disease resistance efforts.

The pathogens, all part of the Colletotrichum species, cause a fungal disease called anthracnose, which lowers yield and produces large, sunken black spots on a variety of fruits and vegetables.

While anthracnose already exists in Australia, the discovery of four new pathogens in chillies raises important new questions about how to better protect Australia's horticultural industry.

The pathogens have a broad host range, meaning they are able to infect other fruits and vegetables, but particularly tropical fruits such as papayas and mangoes.

Professor Paul Taylor, from the Faculty of Veterinary and Agricultural Sciences, said the discovery highlights the need for an effective and efficient diagnostic quarantine system in Australia.

Re export of more than 298 tons of cotton infected with pests

The Quarantine registration number of the shipment was 17873. The reason for re-export was that the shipment was infected with pests on Vietnam plant quarantine and other dangerous pests list, namely Trogoderma granarium Everts (subject to the List No.1 of quarantine).

Quarantine branch Area I issued “Goods Retaining and handling Order” over this shipment so that various units such as Hai Phong Customs Department, Thanh Hoa Customs Department and Customs Branch Area III of Hai Phong… joinly implemented the above mentioned order.

Fungal disease affecting red spring onions in Greece

In a few days, the red spring onion harvest will start in Greece; however, a part of the winter production remains unsold. The question then is whether the new volumes will have a better chance. In fact, problems with a fungal attack have also been recently identified, with the specific pathogen still to be determined, and the results of this are expected to show in the post-harvest stage. Samples from various affected fields have been sent to the Benaki Phytopathological Institute for analysis, but the answer has not yet come.

Although the acreage cultivated with onions has grown by 15% compared to last year, the production may actually remain stable due to the weather conditions, although only time will tell. Due to the low prices of the summer, producers have not been keen in making further investments in the protection of their crops or their fertilisation.

Pet food analysis sparks cat fight over health benefits

Posted August 04, 2016 18:07:15

Consumer group Choice has tested 35 complete wet cat foods for key nutrients — and found many of them do not meet national guidelines.

Poor nutritional content can be problematic for cats, especially those that are sick or elderly, and cat food should meet guidelines set down by the Association of American Feed Control Officials (AAFCO).

The Choice study was prompted by an earlier investigation by the University of Sydney, which stated that a number of commercial pet food products may cause illness to adult cats.

Agricultural News - "We are making great efforts to contain the HLB"

Senasa president said the citrus disease "is contained" but it continues to monitor "all missions" to ensure national healing.

BUENOS AIRES (NAP). "The HLB in Misiones we have a problem but we are making great efforts to contain it and not spread in the country," said the president of the National Health Service and Food Quality of Argentina.

Jorge Dillon warned that "Argentina citricultura can suffer big losses (if spreading the Huanglongbing -hlb-) so we all have to be responsible. From the state are fulfilling the role of enforcing the rules and avoid having people enter with plants or goods from neighboring countries who have it already and which it has wreaked havoc ".

In brief dialogue with NAP during one of his visits to the Rural Exhibition of Palermo, Dillon remarked that in Argentina, the disease "we have it contained. Just have now detected a concrete and troubling case in Misiones".

AU: Protecting horticulture from the Asian honey bee

Biosecurity officers from the Queensland Department of Agriculture and Fisheries, armed with the nets, seek to protect Australian horticulture from the significant potential threat the Asian honey bee and its parasitic companion the Varroa jacobsoni mite could pose.

The pests were discovered recently in north Queensland, and now the foreign raiders are being hunted by biosecurity officers in an intensive three-month operation around Townsville.

The officers are examining flowers, trees, garden beds and other sites in a 10-kilometre radius from the port, to check for unwelcome feral foreign bees, after a hive of several thousand was found at the Port of Townsville.

The Varroa jacobsoni mite is related to the Varroa destructor mite, which has inflicted severe damage on the honey bee industry in the United Kingdom and has been described as the world's most devastating honey bee pest.

Varroa mites can severely compromise honey production as they live on the bees, multiply and lead to deformities in bees which means they cannot forage as effectively.

NZ: Willow pest moves onto apple trees

The giant willow aphid was first discovered in New Zealand in late 2013 and can now be found across 90 percent of the country. The pest has a devastating effect on willow trees, but it has now moved to other hosts as well, including apple trees, it has been discovered.

Poplar and Willow Research Trust general manager Ian McIvor said the pest was proving very hardy, and its spread to other hosts was concerning.

"So they are found in our poplar and willow nurseries on a number of different poplar varieties and they have been reported from a couple of nurseymen to me on ornamentals but also reports of them on apple trees in an apple orchard," he said.

The fact they had moved on to apple trees had come as a surprise, Mr McIvor said.

"Pretty well all of the reports from overseas and all of the research papers have not mentioned other hosts, or they have not mentioned other hosts as being significant."

He could only guess what effect they would have on the fruit, but because they fed lower on the stem than where most of the fruit would be, sugars would be directed to the fruit rather than down the stem, he said.

China finds first case of “kiwifruit rot” in NZ shipment

The Tianjin Entry-Exit Inspection Bureau has announced the interception of two lots of New Zealand-grown kiwifruit, citing the existence of “kiwifruit rot bacteria”.

In a release dated July 18, the bureau said it was the first ever interception of this nature in Tianjin and the country.

The authority claimed the fungal disease Botrytis phariadothide was found in batches of green and gold kiwifruit.

The bureau said while domestic market demand had prompted substantial kiwifruit import growth in recent years, if the pathogen recently found in these shipments were to enter domestic production areas it would cause “incalculable damage”.

The release said it could also be present in apples, persimmons and red eucalyptus trees.

White County added to Emerald Ash Borer quarantine

Yet another county in Middle Tennessee has fallen prey to the Emerald Ash Borer, a pest that targets ash trees.

So far, 48 counties in Tennessee are under quarantine because of the insect, including Davidson, Williamson, Wilson and Rutherford counties.

The Tennessee Department of Agriculture reports an adult beetle was found in a trap in the eastern section of the county.

The beetles can kill an ash tree within three years of an infestation. There are an estimated 261 million ash trees in Tennessee.

You can find a list of quarantined counties here or check out the PDF below.
