Laboratory trials at the University of Nottingham have shown the effectiveness of an oilseed rape biological seed treatment in boosting germination speed at low temperatures and root and shoot development.
Speaking at the Arysta-sponsored Biosolutions Hub, at CropTec, Dr Steve Rossall presented results which showed a one-day increase in germination speed of OSR at 7degC. They also showed a root biomass of more than twice the untreated oilseed rape and a shoot mass about one-third greater than the control four weeks after germination. “There was a massive increase in root biomass,” said Dr Rossall.
The product, Sylas from Arysta, places a high loading of molecules, known as oligosaccharides, extracted from seaweed, onto each seed. They are said to facilitate water movement and uptake in the plant, enabling rapid germination of the seed and development of an enhanced root and shoot mass.
Dr Rossall also conducted trials on foliar applied phosphites in winter wheat which showed up to a 40 per cent increase in root mass 21 days after application. An example of this type of product is Omex’s Kick Start, he said.
“In the early crop establishment phase they can be very beneficial, said Dr Rossall.
“There can be a 0.5t/ha benefit by use of a phosphite biostimulant and I believe they work better when plants are under stress conditions – in the year before last – 2017 they may not have been of benefit but at something like £10/ha this input could be an insurance worth having.”
