It is a non-selective, post-emergence herbicide for the control of annual perennial, broadleaf and grassy weeds. Ammonium salt of Glyphosate 71% SG when applied to foilage reaches the roots andrhizpmes of the plant by the process of translocation, thus destroying the weeds from below the ground. It is especially effective against the difficult to control weeds. Apply to perennial weeds as post emergence application which should be have at least 4 to 8 leaves so that translocation into the plant can occur. Very early treatment of vegetation may reduce weed control but good results are obtained by treating mature plant.
