Hathiyar is a systemic, selective post-emergent herbicide of sulfonylurea group. Hathiyar effectively controls the narrow leaf weeds like Phalaris minor (Mandusi/ Guli danda) and broad leaf weeds like Chenopodium (Bathu), Malilotus (Sainji). Hathiyar inhibits the synthesis of amino acids and stops the metabolic process, with the result weeds dry up and ultimately dies.
