Root and yield-boosting seed treatment gains UK approval for spring wheat
UK spring wheat growers have a new seed treatment option for this season ’ s plantings , with news that the SDHI-based fungicide seed treatment , Vibrance Duo , has gained UK approval for the crop .
This adds to the list of cereal crops that the seed treatment can now be used in , says Vibrance Duo producer Syngenta , a list that has increased since its launch in 2017 , which was chiefly into winter wheat .
“ This new approval marks an important milestone for UK spring wheat , which can often be planted in challenging growing conditions ,” says Gillian Colman , seedcare marketing manager for Syngenta .
“ Vibrance Duo controls a range of diseases that threaten crop establishment . However , as well as doing this and improving
Seed treatment Vibrance Duo ( right ) has been shown to improve rooting and yield in a range of cereal crops , and has now been approved for spring wheat seed
early vigour across a range of cereals in trials , it has also repeatedly been shown to boost root growth and , even more importantly , to increase yield .
“ In spring wheat specifically , independent university research showed that seed treated with sedaxane , the SDHI active ingredient in Vibrance Duo , produced plants with greater root and shoot mass , even in the absence of known disease . Improved rooting effects were also long-lasting , still evident when the crop was coming into ear .”
Establishing good root structures can be particularly important in spring cereals with their short growing season , says Mrs Colman . It is associated with improved access to soil moisture and nutrients , she notes , and greater resilience to drought .
“ In other trial work , Vibrance Duo gave an average of an extra 0.27 t / ha over an alternative seed treatment across three different varieties of spring wheat . This mirrored earlier spring wheat results , which showed a 0.23 t / ha yield increase over an alternative seed treatment ,” she adds .
“ Ever since its initial launch in 2017 , Vibrance Duo has grown in popularity , with the amount of winter wheat seed treated with it doubling each year .
“ As well as being available via static seed processors , Vibrance Duo is available from mobile seed treaters , so growers planting home-saved seed also have access to it ,” Mrs Colman concludes .
