Significant germination and establishment increases with Newton
Research was conducted by Dr. Steve Rossall at the University of Nottingham to investigate the benefits of Interagro’s new biostimulant seed treatment – so how does Newton measure up? Tested on wheat and barley seed, the research showed significant germination and establishment increases with Newton.
Germination 2 days faster with Newton
When the rate of seed germination in winter wheat was tested at 7oC (a soil temperature which late-sown wheat may be exposed to) the time taken to achieve 90% seed germination was improved by two days with Newton treated seed. At 10oC Newton improved germination by one day over naked seed. At both temperatures Newton increased the rate of germination over Vibrance Duo by 1.5 days and 0.75 days respectively.

Root growth increases in excess of 30% with Newton
In the glasshouse, plant growth over the first four weeks after emergence was evaluated. Significant enhancement of root growth was observed, with a smaller increase in shoot growth. In wheat and barley increases in root biomass were commonly in excess of 30% after seed treatment with Newton.

Moreover, a combination of seed treatment followed by a foliar application of Bridgeway gave a root growth enhancement in excess of 50%.
A follow up treatment with Bridgeway increased root and shoot growth even further
How does Newton measure up to other seed treatments?
Newton benefits were markedly superior to the benefits observed by seed treatment with Vibrance Duo. Although this is used primarily as a fungicide, claims have been made that Vibrance Duo can also enhance root growth.
Whilst such proof of concept glasshouse pot experiments may give an enhanced indication of performance, as the plants were grown under ideal conditions, Interagro’s own field trials have supported these conclusions. I believe the beneficial effects of Newton are real and can provide a significant improvement in crop establishment, leading to enhanced and more consistent yields.
Newton is an excellent seed treatment addition to the range of plant biostimulants available to farmers.Steve Rossall, University of Nottingham
