"South Asia produces slightly above 225 million tons of rice (30.7% of global\r\nproduction) on 60 million hectares (37.6% of the global area). India and Bangladesh\r\nare the major rice-growing countries. India contributes around a quarter of global\r\nproduction from 43 million hectares (the largest rice cultivating area). In South Asia,\r\nmanually transplanting rice seedlings into flooded soil (TPR) is the common method\r\nof rice establishment. But direct-seeded rice (DSR) is gaining importance due to\r\nshortage and increased cost of resources. In Sri Lanka 93% of rice is cultivated as\r\nwet-seeded rice. However, the weeds are major constraints in DSR causing higher\r\n(14 to 100%) than in TPR (7 to 80%). Major rice weeds in South Asia include:\r\nEchinochloa crus-galli (L.) P. Beauv., Echinochloa colona (L.) Link., Cyperus\r\nrotundus L., Cyperus iria Linn., Cyperus difformis L., red rice (Oryza sativa L.),\r\nLeptochloa chinensis (L.) Nees, Ischaemum rugosum Salisb., Paspalum distichum\r\nL., Dactyloctenium aegyptium (L.) Willd., Cynodon dactylon (L.) Pers., Echinochloa\r\ncrus-galli (L.) P. Beauv., Eleusine indica (L.) Pers., and Fimbristylis miliacea (L.)\r\nVahl. Weeds flora was reported to vary with location, method of rice establishment,\r\ncultural practices used and associated environment. The small-holders’ traditional\r\nweed control method is hand weeding by hand-held hoe and hand pulling. Hand\r\nweeding is still a major method of weed control. However, the herbicide use is\r\nincreasing due to non-availability and increased cost of labour in several of the\r\nSouth Asian countries. Mechanical weeders are being used by farmers as they\r\nreduce labor use and cost of weeding (72 to 74%). Tillage, mulching, crop rotation,\r\nallelopathic competitive crop cultivars, intercropping, balanced nutrient and water\r\nmanagement and preventive measures have proven to be effective as a component\r\nof integrated weed management in rice of South Asian countries. Herbicide resistance\r\namong weeds in rice was not reported in India, Bangladesh, Nepal and Pakistan.\r\nHerbicide resistant biotypes of E. crus-galli, I. rugosum and C. iria were reported\r\nin Sri Lanka. In South Asia, herbicide tolerant rice is yet to be made available to\r\nfarming community. Weed management research must be focused on identifying\r\nlocation specific effective, environment friendly, economically viable integrated\r\nweed management strategies."^^ . "2017" . . .
