Gro-Root Xtra Special – the first Plant Growth Regulator for soybean growers
Gro-Root Xtra Special (GRX-SP) is a plant growth regulator that has been recently registered by the CFIA for use on soybeans. GRX-SP is a combination of 2 hormones; Auxin (IBA) and Cytokinin (present as Kinetin). Auxins are the plant hormones that stimulate cell elongation and Cytokinins increase cell division. Together these plant hormones modify the physiological processes within the plant and ultimately affect crop yield and quality (ex. increase in the number of flowers/plant; increase in the number of pods/ plant). A 2 year study conducted at 4 sites/year in Ontario and Quebec showed average soybean yield increases of 21%.
Application Timing:
Apply foliarly 80 ml per acre at the 3-5 leaf stage (trifoliate). Available in a 4 L jug (covers 50 acres).
