Weed management in transplanted lowland rice of Champhai District, Mizoram: A review

Weed pose a major significant challenge in lowland rice cultivation leading to considerable loss in production and productivity. Lowland rice is infested by diverse weed population and weed flora including aquatic and semi aquatic weeds. Infestation of weeds resulted to reduction in production and productivity as well as inability to produce maximum potential irrespective of rice varieties. Studies Weed Management have been undertaken but majority of research focused on herbicidal based Integrated Weed Management System. Effective weed management aimed not on eliminating weeds completely but at reducing infestation to a considerable and manageable level. Application of Triafamone 20% + Ethoxysulfuron 10%WG @ 90 g/ acre at 15 DAT with single manual weeding resulted to higher net return with a B:C ration of 2.20.
