Using the pigment marigold varieties “Sesu No.1” as test materials，different concentrations of ‘EFS’ on seed dressing of marigold seeds，different treatments on main morphological traits and yield of potted pigment marigold，foliage spraying on the production of pigment marigold were studied.The results showed that ‘EFS’ could promote seed germination，stem development and the number of flowers increasing，and improved the yield significantly，so ‘EFS’ would extend in the production further.
