about

activator:

    "*  It stimulates the development of micro organisms in the root mass and promotes the growth of roots and rootlets.

    * It improves the root’s biotope and hardens the root cap. This activates the development of a vigorous root mass and a better settlement of the plant in its environment.

    * It allows better resistance to disease and pathogenic moulds (powdery mildew, dumping off in seedlings and cuttings, etc)."
