The active ingredients in CytoGro, cytokinins and natural synergists, stimulate root growth, producing turf that is more resistant to environmental stress caused by drought, disease, insect damage, and temperature extremes.

CytoGro aids in the uptake of fertilizers, pesticides, and fungicides, saving time and money as well as helping turf managers become less chemically dependent.

CytoGro has been tested by many renowned turf grass experts including: Dr. Richard Schmidt, Virginia Polytechnic Institute; Dr. Jack Fry and Dr. Rock Gaussoin, Kansas State University; and Dr. Carlos Blanco-Montero, University of New Mexico.
