A mild autumn and winter combined with a build-up in aphid numbers since the loss of neonicotinoid seed treatments has resulted in the highest level of Turnip Yellows infection ever seen in the UK this year. The average rate of infection this spring was 84%, compared to just 49% last year, however, more worryingly still

The average rate of infection this spring was 84%, compared to just 49% last year, however, more worryingly still

Two new varieties on the AHDB Recommended List this year offer growers the opportunity to protect their crops from the turnip yellows virus while also achieving top yields. When the first TuYV resistant variety Amalie was introduced to the market in 2014 by breeder Limagrain, the pay-off for aphid resistance was low yields in normal

At the very top of the AHDB Oilseed Rape Recommended List for 2019/20, sits a variety with a UK gross output of 104% over control, Aspire. This conventional winter oilseed rape takes the leading position as the variety with the highest gross output on both the east, west, and northern list, based on its seed

Limagrain UK’s approach of breeding varieties that offer valuable traits and end-market suitability continues to see further success as a new oilseed rape and two spring barleys are added to the 2018/2019 AHDB Recommended List. Hybrid oilseed rape variety Architect offers a step-up in yields for varieties that also carry TuYV resistance, and has been

Hybrid oilseed rape varieties Architect and Aquila sit at the top of Agrii’s UK national trials harvest results. Architect takes the lead position yielding an average of 4.74 t/ha over all sites of which is 112% over control, closely followed by Aquila at 4.68 t/ha; 110% of control. Bred by Limagrain UK, both varieties have

Oilseed rape yields could be impacted this season as levels of TuYV infection are confirmed to be as high as 100% in some sites, and generally indicate high levels of infection across most of the country, according to plant breeders Limagrain UK. Turnips yellows virus (TuYV) is spread by the peach potato aphid (Myzus persicae), and can

Choosing varieties with the genetic traits or agronomic characteristics suitable for your farm can reduce risk, protect yields and give more consistent results, is the message from leading plant breeders Limagrain UK. Making OSR variety choices based on the conditions in which they are to be grown is fundamental to a profitable crop, and this

On many arable farms today, alongside a need to choose arable crops that will deliver on farm in terms of both yield and quality, rotational and political pressures as well as sporting considerations have driven an increase in a whole range of forage, soil improvement, environmental and game cover crops. Leading plant breeders Limagrain UK

Harvest results from two AICC (Association of Independent Crop Consultants) oilseed rape trials sites have demonstrated the value of sound agronomics when it comes to final yield. Amalie, the TuYV resistant conventional oilseed rape variety, has performed well over expectation this year yielding 108% over control, across 27 varieties in the trials, with yields of

Amalie, the resistant TuYV OSR variety, has yielded 5t/ha in its first commercially recorded harvest, a tonne per hectare over non-resistant varieties on the same farm. Harvested at the Hutchinsons Blackgrass Centre at Brampton on Monday 20th July, the 30ha block of Amalie yielded as much as 7.5t/ha in some places but averaged out on

This year’s first harvest of conventionally grown candidate oilseed rape variety Amalie has yielded a strong 5t/ha, according to early weighbridge results. A 30ha plot of the conventional Limagrain variety, which is tolerant for the yield-robbing disease turnip yellows virus (TuYV), was harvested on Monday 20 July at Hutchinsons site in Brampton near Cambridge. It

WITH reports of very high TuYV infection levels being recorded from across the country, many oilseed rape growers will be considering their options for the coming season. One viral disease they will be looking to manage in oilseed rape, is Turnip yellows virus (TuYV). Presenting the results from a nationwide survey at Cereals, Dr John

OILSEED rape crops in Yorkshire are reported to have infection rates as high as 72 per cent for Turnip yellow virus (TuYV). Dr John Walsh of Warwick University led the research for Limagrain UK and gave his findings at Cereals 2015. “Results from across the country are showing worryingly high levels of infection with some

With reports of very high TuYV infection levels being recorded from across the country, many oilseed rape growers will be considering their options for the coming season to manage for what is considered it be the most important, yet least understood, viral disease in oilseed rape, Turnip yellows virus (TuYV). Presenting the results from a

Oilseed rape crops have been struck by up to 92% turnip yellows virus (TuYV) infection in parts of England this year, a new survey has confirmed. The virus is spread by infected aphids and can cost growers up to 30% of their yield in bad cases. The findings were described as “worrying” by John Walsh

Winter oilseed rape crops are being overwhelmed by turnip yellows virus (TuYV) this year, a new study says. The nationwide survey, which was run by agrochem group Bayer and distributor Hutchinsons, found TuYV infection present in a mean average of 60% of winter crops. The survey took samples from 75 plots in counties from all

EARLY results from a nationwide survey indicate high incidences of TuYV infection in oilseed rape. Conducted by Dr John Walsh of Warwick University on behalf of breeders Limagrain UK, the survey, which will be completed by the end of May, will provide a comprehensive indication of TuYV infection hot-spots across the country. TuYV is thought

Oilseed rape variety Amalie is being reconsidered for the HGCA Recommended List, because of its valuable resistance against turnip yellows virus (TuYV). Agronomists predicted an increased virus threat after the loss of neonicotinoid seed treatments in December 2013. This is because the virus is spread by aphids, the key one being the peach potato aphid

Early results from a nationwide survey are indicating high incidences of TuYV infection in the current oilseed rape crop. Carried out by Dr John Walsh of Warwick University on behalf of breeders Limagrain UK, the survey which will be completed by the end of May, will provide a comprehensive indication of TuYV infection hotspots across

Early results from a nationwide survey are indicating high incidences of TuYV infection in the current oilseed rape crop. Carried out by Dr John Walsh of Warwick University on behalf of breeders Limagrain UK, the survey which will be completed by the end of May, will provide a comprehensive indication of Turnip Yellows Virus (TuYV)

Oilseed rape crops in parts of England are seeing rates of turnip yellows virus (TuYV) infection as high as 80% this season, according to early results from a nationwide study. The virus is spread by aphids and is estimated to cost the industry £100m/year, with up to 26% loss in yield. So far the survey

Carried out by Dr John Walsh of Warwick University on behalf of breeders Limagrain UK, the survey which will be completed by the end of May, will provide a comprehensive indication of Turnip Yellows Virus (TuYV) infection hotspots across the country. TuYV is thought to be the most important, yet least understood viral disease in

This autumn could see the perfect storm for Turnip Yellows Virus (TuYV) infection in early drilled oilseed rape crops warns plant breeders Limagrain UK. “An early harvest and ideal drilling conditions has meant that many oilseed rape crops will be drilled over the next two weeks into near perfect conditions. Crops will therefore be quick

Cereal and oilseed rape aphids are likely to fly considerably earlier this year, according to AHDB’s Aphid News. The service, led by Rothamsted Research, revealed the temperature in January and February was considerably higher than the long-term average across the country – by 1 to 1.5C in the north and around 2C in the south

Getting your winter oilseed rape crop past the threat of flea beetle will be difficult without neonicotinoids but preventing Turnip Yellows Virus (TuYV) infection by aphids, which are now largely resistant to Pyrethroids will be virtually impossible. Is TuYV really such a threat? This is what the experts say: “TuYV is probably the most important,

Growing oilseed rape in the absence of neonicotinoid seed treatments and the subsequent crop losses from flea beetle and Turnip yellows virus (TuYV) is a major concern looking ahead to this autumn says Philip Marr, OSR expert with Agrii. “With OSR selling at £250/tonne no-one wants to invest in crops that won’t reach their full

Amid concerns over the impact of the suspension of use of some neonicotinoid insecticides on turnip yellows virus (TuYV) control in oilseed rape (OSR), there are hopes a new TuYV resistant OSR variety will help growers limit the effects of the disease. Winter OSR variety Amalie from plant breeding business Limagrain is the first variety

A virus that can cut OSR yields up to 30% will be a greater threat from next autumn. But the first resistant variety may offer a solution, as Richard Allison found out. A variety of oilseed rape resistant to turnip yellows virus offers a way to overcome the increased virus threat expected after the loss
