About Topper 77 Herbicide

Topper 77 is non-selective herbicide used by farmers to control weeds. It is manufactured by Crystal Crop Protection Ltd. and contains Ammonium Salt of Glyphosate 71% SG as the active ingredient. Farmers use Topper 77 to control weeds in tea plantations and non-crop areas. It is especially effective against weeds that regrow from roots and rhizomes.

Topper 77 Herbicide works by entering through the leaves of weeds and moving down to the roots. It is used to control broadleaf weeds, grasses, and sedges in tea gardens and non-crop areas. Farmers generally spray it when weeds are actively growing and have sufficient leaf area for herbicide absorption.

Product Specifications

Mode of Entry: Systemic

Time of Application: Post-emergence

Mode of Action: Topper 77 herbicide contains Glyphosate, a non-selective herbicide, which inhibits the EPSP synthase enzyme in weeds. This prevents weeds from producing the amino acids required for growth. After spraying, the herbicide moves from the leaves to the roots and underground rhizomes, gradually drying the weed plant. Yellowing and wilting may appear within a few days, and complete drying usually occurs within 7–14 days, depending on weather conditions and weed growth stage.
