Headmaster based on sulfosulfuron 75% WG. Headmaster is a systemic, selective post-emergent herbicide of sulfonylurea group. Headmaster effectively controls the narrow leaf weeds like phalaris minor (mandusiguli danda) and broadleaf weeds like chenopodium (bathu), malilotus (sainji). Headmaster inhibits the synthesis of amino acids and stops the metabolic process, with the result weeds dry up and ultimately dies.
