Yield uplift technology for seed
Our biostimulant technology for seed treatment application, branded under the name Symiro™, significantly increases yield. It is safe for germination and is thought to directly stimulate plant growth through promotion of cell division and expansion, enhancing leaf photosynthesis. Initially designed for use on soybean seed, Symiro has been shown to enhance nodulation in legumes resulting in increased nodule number.
Key benefits of Symiro
Significant yield increase of 5.6% demonstrated in field trials.
Safe on germination.
Increases nodule numbers leading to improved nitrogen fixation.
- Promotes plant cell division and expansion.
- Improves photosynthesis.
Symiro mode of action
How does Symiro work?
Symiro contains a naturally occurring compound known to be secreted by rhizobia for plant signalling. This has a number of effects. Firstly, the plant cells make more sugars available to the rhizobia. Secondly, the plant increases root respiration, which in turn increases CO2 availability for the rhizobia. Other compounds thought to be useful to the rhizobia are also synthesised by the plant. As a result of these processes beneficial to the rhizobia, nodulation, and therefore nitrogen fixation, is increased.
As well as benefitting the rhizobia, Symiro is also thought to enhance plant growth more directly, through the promotion of cell division and expansion, as well as through the enhancement of leaf photosynthesis.
