Super pest survives winters

Diamondback Moth: Resistent to pesticides and winter weather

A ‘SUPER PEST’ moth resistant to a class of common plant protection is now also capable of surviving through the UK’s cold winter conditions, according to new research.

Diamondback moths have arrived in their tens of millions in the past few days with more expected. Crop experts have warned the animals could have a devastating effect on cabbages and other vegetables

Diamondback moth (DBM) caterpillars feed on crops including cabbage, broccoli, swedes and Brussels sprouts, causing cosmetic damage, which could result in the loss of up to 100% of the crop. Brassicas were worth more than £200m to UK agriculture last year.

The pests, which have developed resistance to the pyrethroid class of plant protection products often have reduced fitness levels so don’t survive through winter. However, experts from Rothamsted Research and AHDB are concerned because this is not the case with this new strain of moth.

Growers are being asked to submit samples of the DBM either when seen through winter, or in spring when numbers start to rise, to aid the continued monitoring and development of control strategies to manage the pest.

Dr Dawn Teverson, Knowledge Exchange Manager at AHDB, said: “This new research reconfirms what we found last year. It’s important that Brassica growers are aware of this pyrethroid resistance and plan their crop protection programmes to treat against diamondback moths, accordingly.

“If pyrethroids are used, not only does this now fail to control DBM but it could also kill beneficial insect predators which would naturally help control the pest, further exacerbating the problem.”

Pyrethroid resistant DBM have been found overwintering on swede crops grown under insect netting.

Dr Steve Foster, research entomologist at Rothamsted Research, said: “We have seen in aphids that those which have developed resistance may not survive the winter, however this doesn’t seem to be the case with this new strain of DMB.

“The identification of pyrethroid resistance in this season’s population of moths suggests that they are descendants of 2016’s migrating diamondbacks and therefore that the resistance hasn’t stopped them from surviving over winter.”

Andrew Rutherford, farm and agronomy manager at K. S. Coles, said: “This study has been extremely helpful to growers, allowing them to increase their understanding of the pests they are trying to control and which actives will be effective.”

The diamondback moth is often described as a ‘super-pest’ because it has a rapid lifecycle, providing more opportunities for resistance to develop through gene mutation. In 2016, Steve Foster at Rothamsted Research tested three diamondback moth samples for resistance from Lincolnshire, Suffolk and Scotland. All three samples were resistant to pyrethroids.

AHDB’s co-funded project ‘FV 344a Monitoring and Managing Insecticide Resistance in UK Pests’ is currently due to end in March 2018.

Access to EU Single Market and Customs Union critical for rural Wales

Published

on

Brian Thomas: ​​FUW Deputy President

N​EWS that Northern Ireland could be granted access to the European Single Market and Customs Union shows that it is possible to achieve what the Farmers’ Union of Wales has been calling for since the EU referendum.

Speaking from his farm in Pembrokeshire, ​​FUW Deputy President Brian Thomas said: “Different parts of the UK can’t be treated differently and we therefore call on the UK government to ensure that Wales, given its heavy reliance on red meat exports to the EU, is given the same treatment. Should this deal be offered and come to fruition we fully expect to have the same offered to us.

“In the farming community there is a real sense of worry, alarm and anger about the state of Brexit negotiations, and how the current state of play compares to what was promised by many before the referendum.

“And whilst we recognise that the Irish border situation presents some unique challenges that need to be overcome, rural Wales has challenges of its own, such the economic challenges we have long highlighted. We need to recognise the impact that failure to secure such access and reach agreement for Wales could have. Denying Wales access to the Single Market and Customs Union would have catastrophic consequences, as recently highlighted in scenarios from the FAPRI and Horizon reports.”

Farmers from Wales and Oz join forces to showcase ‘lightning lamb’

Jamie Heinrich and Richard Roderick: At the HCC lightning lamb cookoff

A ‘LIGHTNING LAMB’ cooking challenge featuring award-winning sheep farmers from both sides of the globe was one of the highlights of the recent Royal Welsh Winter Fair in Builth Wells.

Surveys show that families in Britain have only 32 minutes on average to prepare an evening meal nowadays, as opposed to an hour in 1980. Hybu Cig Cymru – Meat Promotion Wales (HCC) is taking steps to emphasise lamb’s quick-cook credentials, so enlisted the help of Australian farmer Jamie Heinrich and Breconshire’s own Richard Roderick in a ‘cookoff’ to prove it!

Jamie Heinrich hails from Kangaroo Island near Adelaide in South Australia, and operates a 2000-acre holding farming Poll Merino and White Suffolk sheep. His visit to Wales is part of a Nuffield Australia scholarship to study how to encourage young entrants to the industry.

Richard Roderick lives at Newton Farm near Talybont-on-Usk in the Brecon Beacons. He is a past HCC Scholar, and has won several farming accolades including the Silver Lapwing Award in 2016 for his environmental management. Earlier this year he featured on the BBC series ‘Nadiya’s British Food Adventure’.

With the help of HCC cook Elwen Roberts, Jamie rustled up a rapid Welsh Lamb stir-fry with oriental flavours, while Richard’s creation was a pan-fried leg steak with red wine sauce. After tasting and judging by members of the audience, the two delicious dishes could not be separated, so the Wales vs Australia match ended in an honourable draw.

“When I came over to Wales I certainly didn’t anticipate getting involved in a cookoff to promote lamb!” said Nuffield Australia Scholar Jamie Heinrich. “Many of the challenges for the industry – recruiting younger farmers and making sure that lamb is appealing to young consumers who are pushed for time – are the same the world over. I’m very much looking forward to the rest of my trip to Wales and Europe.”

HCC’s Elwen Roberts commented: “It was great fun to challenge two farmers to come up with a quick and tasty lamb recipe. They both did extremely well, and the Winter Fair audience loved seeing and tasting the food.”

“It’s important to emphasise that lamb can be an excellent choice for a quick evening meal,” she added. “HCC has recently launched a mobile-phone-friendly recipe selector on the eatwelshlamb.com website, to help give consumers inspiration for lamb dishes while on the move.”

Arwyn Davies, Business Development Manager: With Angela Sawyer, Senior Food Technologist, Food Centre Wales

THE FOOD CENTRE WALES team were at the Farm Business Innovation show 2017 offering advice and support to businesses in the food and drinks industry.

The event held on November​ 8-9​ in Birmingham highlighted the continued interest in adding value to farm produce, particularly in Wales.

Arwyn Davies, Business Development Manager at Food Centre Wales, said​:​ “As this was the first time we had exhibited at the Farm Business Innovation show. We went in with an open mind, but we are pleased to report that it was a very successful two days. We spoke to many farm owners during the two days, many of whom were from Wales.”

Arwyn Davies’ talk on ‘Farm Diversification into Food Processing – Exploring Opportunities & Avoiding Pitfalls’ was very popular with every seat taken.

Councillor Gareth Lloyd, Cabinet Member with responsibility for Economic and Community Development said​:​ “The Team at Food Centre Wales were interested to hear all the ideas and plans people had for diversifying their farm businesses. The Centre’s food technologists were on hand to offer advice on how farmers could add value to their food produce and what could be done do to help them along the process. If you didn’t get a change to call in at the stand, the Team are more than happy to help at the Centre.”

Food Centre Wales will be following up with inquiries received at the show, with the aim to help many develop their food products and reach new markets.
