Global plant pest standards agreed

Global pest: The Oriental Fruit Fly is rapidly spreading

THE BODY charged with keeping global trade in plants and plant products safe has adopted several new phytosanitary standards aimed at preventing destructive agricultural and environmental pests from jumping borders and spreading internationally.

The standardized norms developed by the International Plant Protection Convention (IPPC) cover a range of strategies and techniques used to prevent the introduction and spread of plant diseases and pests to new environments, thereby avoiding their often-devastating impacts on biodiversity, food security and trade.

“This is challenging work with high stakes: each year an estimated 10-16 percent of our global harvest is lost to plant pests. A loss estimated at $220 billion​,​” FAO Deputy Director-General Maria Helena Semedo said at the opening of this year’s IPPC annual meeting in Rome.

Some $1.1 trillion worth of agricultural products are traded internationally each year, with food accounting for over 80 percent of that total, according to FAO data.

New measures adopted this week by the IPPC’s governing body, the Commission on Phytosanitary Measures(CPM), include:

Standard on the use of various temperature treatments against agricultural pests. The standard aims at ensuring that such treatments are consistently and effectively used in different operational contexts.

The norm covers cold treatment techniques that freeze and kill pests as well as those that raise temperatures past their survival threshold. This can be achieved by submerging them in extremely hot water or exposing them to super-heated steam (for commodities vulnerable to drying out, such as fruits, vegetables or flower bulbs) or dry heat (ideal for low moisture-content items such as seeds or grain).

Revised standard for sanitation of wood packing materials. An existing standard, known as ISPM-15, was updated to include the use of sulphuryl fluoride — a gas insecticide — and new-generation heating technologies that employ microwave and radio frequency waves to generate pest-killing temperatures deep inside wood products.

An expanded standard on the use of heat vapour to kill Oriental Fruit Flies. The highly destructive, fruit-attacking Bactrocera dorsalis originated in Asia but has now spread to at least 65 countries. Its presence in Africa, where it first appeared in 2003, costs the continent an estimated $2 billion in annual losses due to fruit export bans. The control technique outlined under the new measure kills 99.98​%​ of the bug’s eggs and larvae when used correctly.

The IPPC Commission also approved revisions that streamline existing standards targeting fruit flies to make it easier for countries to comply with them and improve their effectiveness, as well as revisions to a standard that establishes best-practice benchmarks for the operation of national pest surveillance programs.

And it endorsed new diagnostic protocols for sudden oak death, a fungi-like organism of unknown origin that attacks a wide range of trees and shrubs in nurseries, introduced into western North America and western Europe through the ornamental plants trade. And it approved new diagnostic protocol for tospoviruses, which affect 1,000 plant species and are causing devastating losses, especially to tomato, potato and squash and cucumber yields.

BENEFITS AND RISKS OF GLOBAL TRADE

The dangerous hitchhikers carried by global trade — plant pests and diseases — once introduced into new environments can quickly take root and spread, impacting food production and causing billions in economic damages and control cost. One recent study in East Africa, for instance, found that just five invasive alien species could be causing as much as $1.1 billion in economic losses annually to smallholder farmers in the region.

Not only can fruits, crops and seeds become infected, but the containers and boxes they travel in, as well. Packaging for overseas shipments is commonly constructed from wood, which is relatively inexpensive, and easily manufactured — but also easily infested with a variety of bark and wood pests, and so act as a vector. Timber and wood-made products like furniture can harbour stowaways, also.

This means that not only are food crops at risk, but forests and trees as well. Recent studies shared during this week’s meeting have shown that the loss of tree cover due to invasive pests may result in an increase in stress related-diseases and possibly elevated human mortality rates.

In another example, the Republic of Korea was recently forced to cut down some 3.5 million trees as a result of the pinewood nematode, and over the past three decades has spent nearly a half a billion dollars on control programs to fight this deadly pest. Additional sums have been spent in Canada and the United States in attempts to stop the thus far unstoppable Emerald Ash Borer.

The need to contain threats such as these are why the IPPC was established in 1952. Since then, it has promulgated some 100 standards covering a broad range of phytosanitary issues. It also runs a number of programs that work to share information on best-practices and build the capacity of developing countries to manage plant diseases and pests, both at home and in trade flows.

Alpaca settle in on Welsh hills

Published

on

A HERD of alpaca at Aberystwyth University’s upland research centre welcomed two new arrivals during the Covid-19 lockdown.
One male and one female baby alpaca, known as cria, were born at the Pwllpeiran Upland Research Platform and are settling down to life in the Cambrian Mountains.
They are the first cria to be born on the University’s land and to be registered under the centre’s new stud prefix ‘Peiran’.
Peiran Champagne and Peiran Cosmopolitan join a small herd of alpacas who arrived at Pwllpeiran in October 2019 as part of a new research project.
Scientists want to see whether the South American alpaca is suited to life in the Welsh hills and could provide new opportunities for uplands farming.
These long-necked animals, similar to the llama, are renowned for the quality of their fibre (wool) and are happy to feed on low quality grasses which are often snubbed by sheep.
The research project is being led by Dr Mariecia Fraser at the Pwllpeiran Upland Research Centre, which is part of the University’s Institute for Biological, Environmental and Rural Sciences (IBERS).
“These are changing times for Welsh upland farming, with the next round of support payments expected to push for a shift away from primary agricultural production towards nature conservation and carbon reduction. In setting up a research herd of alpacas at Pwllpeiran, we want to test whether the alpaca could offer hill farmers a viable alternative to sheep.
“As well as producing high quality fibre, camelids like alpacas have evolved adaptations to enable them to live off poor quality tussock grasses in the Andes, and are happy to tuck into invasive grasses such as Molinia. These forages grow in abundance on the Welsh uplands but tend to be shunned by native sheep. We’ll be looking at the impact of their grazing and how well they could fit in to traditional patterns of farming here,” said Dr Fraser.
The establishment of the initial research herd is being funded by the Joy Welch Educational Charitable Trust, which was set up by the Aberystwyth alumna in 1988.

Beef calf registrations increase

Published

on

NEW figures released by the British Cattle Movement Service (BCMS) suggests that the number of beef calves registered in Wales in the first five months of 2020 is the highest it’s been for several years.
Across Britain there has been an overall rise of 1.2% in calves – both dairy and beef – registered between January and May 2020, compared to the same period last year. In Wales the figure is higher, with an increase of 3.1%.
According to analysis by Hybu Cig Cymru – Meat Promotion Wales (HCC) the statistics reflect a range of factors, including a trend of producing more cross-bred calves from the dairy herd.
Some of the beef breeds and cross breeds showing the biggest increases in terms of calf registrations in Wales include the Aberdeen Angus (up 11.7%) and Hereford (up 4.8%), whilst both Charolais and British Blue registrations are up just over 4%.
The 2020 figures are a contrast to the last five years, where BCMS calf registration data has indicated a flat picture in the Welsh beef registrations.
HCC market analyst Glesni Phillips said, “These figures could show a positive sign for the future of the beef industry in Wales, and reflect broader trends in both the beef and dairy sectors.
“This comes despite the beef sector being hit by uncertainty in recent times. A combination of market conditions led to low farm-gate prices last year, and demand fluctuated widely in the early stages of the Coronavirus lockdown as pubs and restaurants closed their doors.
“However, we’ve seen encouraging consumption figures throughout Britain in the second half of the spring, with great support from consumers for home-produced beef, with its high standards of welfare and environmental sustainability.”
One high-profile new entrant into the beef sector is international rugby referee Nigel Owens MBE, who has recently started his own ‘Mairwen’ herd of Hereford cattle in Carmarthenshire.
“Having worked at Wern Farm Drefach when I was younger it had always been a dream of mine to keep my own herd,” said Nigel, who has built up to around 30 cattle so far on a 116-acre holding, “and if anything the lockdown has given the chance to get things up and running more quickly, as we’ve been able to get on with fencing, hedge-laying and developing our soil and pasture.”
Nigel added, “Each breed has its supporters, but from an early age I recall visiting my uncle and aunt’s farm, Pentwyn in Llannon, who had a Hereford bull running with the dairy herd. My cousin Helen and Gwyndaf near Aberaeron who run the Creuddyn Hereford herd have also been a valuable source of advice. For me, the cattle have a calm nature and calve easily. They’ll also produce good-quality meat which is important as we develop the business in future.”

New edition of Welsh meat ‘Bible’ launched

Published

on

HYBU Cig Cymru – Meat Promotion Wales (HCC) has launched the latest edition of its ‘Little Book of Meat Facts’, the annual digest of facts, figures and trends for the nation’s lamb, beef and pork industries.
Among the key figures in this year’s edition were that Welsh red meat production was worth an estimated £690 million in 2018, compared with £677 million the previous year.
In 2019, total throughput of cattle and calves in Welsh abattoirs stood at 147,600 head, with total beef production totalling 42,900 tonnes (up from 40,000 tonnes the previous year). Throughput of sheep and lambs stood at 3.3 million head, with total sheep meat production totalling 63,400 tonnes, compared with 60,800 in 2018.
France remained the largest destination for lamb exports, but with important growth in trade with Germany which is now in a clear second place. Beef and lamb exports were mostly to Europe, although with significant trade to other markets in the Middle East, East Asia and Canada.
The Little Book also contains information on what kinds of meat British consumers are buying and from which retailers, as well as data on key industry measures such as carcase classification.
HCC Data Analyst Glesni Phillips said; “We usually launch the Little Book of Meat Facts at the Royal Welsh Show, so that farmers and other stakeholders can browse the latest statistics.
“Of course, this year that’s not possible, so we’re launching it virtually and making it available on our website.
“What all the statistics show is that, despite uncertainty surrounding Brexit and now of course the disruption of COVID-19, the red meat sector is hugely important to the Welsh economy. It’s the backbone of rural communities, and also employs large numbers in auction markets, processing and the supply chain, as well as supporting brands which are symbols of our nation’s high-quality food across the world.”
