No middleman ensures best quality at wholesale prices.
HPM Heera-77 herbicide is a selective, post-emergence solution containing 2,4-D amine salt at 58% SL. It controls a wide range of broadleaf weeds in crops such as wheat, maize, sorghum, sugarcane, potato, and even in aquatic and non-crop areas. By mimicking natural plant auxins, it disrupts uncontrolled cell division in weeds, causing abnormal growth and vascular collapse, while preserving grasses and cereals.
Heera 77 herbicide’s systemic action ensures that the 24d herbicides move throughout the weed from roots to leaves, delivering complete control. Its post-emergence formulation makes it easy to apply as a blanket spray, reducing competition and improving crop yield. Heera-77 is suitable for terrestrial and aquatic weeds, making it versatile for multiple crop systems and non-crop areas like irrigation channels or fence lines.
For guidance on safe herbicide application, see our Weed Management Practices. The ICAR Weed Science Research Guidelines provide detailed data on the efficacy of 2 4-d herbicide dose and application safety [ICAR 2022].
