HPM Heera-77 Herbicide (2,4-D Amine Salt 58% SL)

HPM Heera-77 is a selective post-emergence herbicide formulated with 2,4-D Amine Salt 58% SL. It provides broad-spectrum control of annual and perennial broadleaf weeds in major crops such as wheat, maize, sorghum, sugarcane, potato, and also in aquatic and non-crop areas. Its systemic mode of action ensures complete weed elimination by moving from the leaves to the roots, disrupting natural auxin balance, and causing uncontrolled growth, tissue rupture, and vascular collapse in susceptible weeds.

Mode of Action

Heera-77 imitates natural plant auxins, causing uncontrolled cell division and abnormal growth in broadleaf weeds. This results in rapid twisting, epinasty, tissue rupture, and eventual plant death. Its systemic nature allows the active ingredient to move throughout the weed, ensuring complete elimination from leaves to roots.
