  • DSV United Kingdom Ltd. - Don't rely on Verticillium Wilt Resistance Claims
    2405 Contact Product links Product Overview Please Wait www dsv uk co uk News Don t rely on Verticillium Wilt Resistance Claims Don t rely on Verticillium Wilt Resistance Claims Vericillium wilt is a growing threat to oilseed rape production in the UK with the recent increase in tighter rotations making the problem worse due to carry over of the causal agent in the soil plant debris and farm saved seed Infection with the pathogen Verticillium longisporum starts at the seedling stage and when crops are grown in short rotations new crops are closer to the previous year s stubble and subject to spore transfer from crop residues and volunteers Once plants are infected the disease spreads up through the xlylem at stem extension before the first symptoms appear as the plant ripens This late visibility of the disease is one of the main reasons it is so difficult to manage by the time you see it it s too late but the impact of the disease can be considerable First signs are grey discolouration and striping on stems which then leads to premature ripening with plants dying back early and pods shriveling In some parts of mainland Europe yield losses have been reported as high as 50 and whilst the disease can be controlled with robust fungicide programmes timing is difficult and indentifying the extent of the damage problematical when there are few outward signs to guide you Varietal choice can play a large part in reducing potential fungicide costs but tolerance to the disease differs widely across different varieties Claims of resistance are misleading as all varieties will suffer from verticillium wilt to some degree in the right circumstances but whilst some will suffer minimal damage others can be devastated Some varieties like Compass are particularly tolerant suffering less than 5 of plants affected when exposed to the disease whilst other popular varieties can have virtually all their plants infected in the same situation Agronomy company Agrivice Ltd has looked into this varying level of tolerance to the disease with trials using close rotations to try and split apart varietal differences under increased stress The idea being that this would identify which ones coped best in terms of both yield and susceptibility to verticillium wilt Of 31 oilseed rape varieties tested Compass not only achieved the best yield at 6 21 tonnes ha corrected to 9 moisture content but also the highest oil content at 47 18 giving it the highest gross output by some margin But importantly the variety also achieved the lowest verticillium wilt score in the trial Further analysis carried out by Dr Peter Gladders of ADAS revealed Compass showed no incidences of dead stems caused by the disease whilst others had up to 90 affected Hutchinsons has also undertaken trials with Pete Gladders with the same consistent differences in infection levels between varieties being seen some varieties experiencing 100 plant death This year despite high disease pressure in some parts Compass has lived up

  • DSV United Kingdom Ltd. - Spring cropping and cover crops battle blackgrass
    News Spring cropping and cover crops battle blackgrass Spring cropping and cover crops battle blackgrass Blackgrass problems have burgeoned across the country and in the fight against it farmer Jim Bullock has significantly increased his spring cropping area which now makes up over half of the total acreage We grow around 280ha acres of crops a year he explains But in recent years we ve relied less on winter cropping and increasingly grown spring crops to allow us to control blackgrass better Mr Bullock points out that on his predominantly silt clay loam soils he is able to achieve the same margins with spring oilseed rape as he would with winter oilseed rape and it helps ease the workload In addition to this spring crops have provided much more reliable options on Mill Farm in Malvern with waterlogging often making autumn establishment much more challenging The move has also allowed Mr Bullock to adopt an approach of keeping land covered over winter utilising DSV s TerraLife cover crop mixes The approach uses specially developed mixes of alternative crops and grasses designed to work at different levels within the soil profile to help improve the soil structure and replace organic matter One of the key elements is not to lose what nutrients we have applied and one of the main attractions of TerraLife is that you ve got species with different rooting depths so they are going to bring nitrogen from one level and phosphates from another up to the surface so these are available to crops the following year Part of the thinking behind our approach is that we want to direct drill everything in the future and to do this we need to improve the soil s friability to allow the drill to work better and also increase its organic matter in the top 10 15cm We don t have any livestock so I can t add a lot of farm yard manure to the land so basically I m trying to grow our own compost Following a visit to Germany three years ago where Jim saw the concept in action and then again at UK trials he decided it was time to give it a try Growing Last year Mr Bullock drilled two different mixes from the German plant breeder DSVs Terralife range including MaizePro which contains 13 different pant types including field peas forage rye clovers vetches and phacelia and Biomax which includes bristle oats buckwheat sunflowers oats mustards and sunflower The previous crop was combined the straw chopped and levelled and glyphosate applied to clear up any weeds He then direct drilled the mixes with a basic tined drill at 10cm depth I thought we should treat it as a proper crop if we wanted to get the best results from it so we rolled the seedbed put on some slug pellets applied 18 46 fertiliser and the first plants started coming through in just 4 5 days Both mixes grew away rapidly in the warm

  • DSV United Kingdom Ltd. - Farmers fall for Incentive
    Sometimes you have to look behind the numbers to see the true nature of a variety and the stand out aspect of Incentive 45 in addition to its outright yield is its consistency across all trial sites over a number of pretty challenging years The fact that it is topping both lists also underlines the strength of its genetics and importantly its ability to perform well in a variety of different growing conditions which in light of the years we have just experienced is close to the hearts of many growers In the business for over 40 years Geoff took the unprecedented step of sourcing as much of the seed as he could ahead of its launch and encouraged some of his best customers to grow it One grower who has caught this infectious enthusiasm is Geoff Garratt of Hill Farm Widmerpool Notts who has put his whole 104ha of oilseed rape over to the variety for 2014 Heavy boulder clay and rising land mean historically we ve got very variable results with Oilseed Rape highest yield has been 4 2t ha but its been down as low as 2 5t ha he explains Establishment is key for us usually if we get 50 germination we think we ve done well But crop failures in 2012 really brought it home to me and I knew I had to find a variety with really good vigour to guarantee it gets away properly and is more winter hardy generally It s going in after Wheat which can be quite late here so it s just got to get up and get going as quickly as possible and establish well come what may Incentive just seemed to tick all the boxes and although it wasn t on the RL Geoff was impressed enough by its results to decide to use it exclusively across the farm We started drilling it on 26 th August and were finished by the 4 th October We used one bag for every three ha with a target of 50 seeds ha From the word go it has been a great looking crop It just kept coming and despite it turning dry it just kept growing Our fieldsman says it s the cleanest crop he s seen this year which I put down to its early vigour letting it grow through any early disease threat and pest attack In fact despite being surrounded by woodland the crop has suffered no pigeon damage whilst neighbouring crops have been hit badly I see the pigeons in the fields nearby and they fly over here but in ten minutes they re gone They just don t seem to like the Incentive for some reason Geoff admits it was a bit of a gamble putting his whole acreage down to Incentive but says the fact that the variety subsequently came top on both Recommended Lists for 2014 15 was somewhat reassuring I know I made the right decision It s a really even
