"Rice yields increased several folds in many areas of the Asian-Pacific region, since\r\nthe mid-1960s, due to introduction and adoption of new rice cultivars and associated\r\nimproved production methods including weed management. The most commonly\r\nused weed control methods in rice include manual weeding, land preparation, cultural\r\nmethods, such as manipulating the cultivar grown and planting density, water level\r\nmanagement, herbicide application, crop rotations, crop residues use and\r\nmanagement. Over the years, these methods have been integrated with preventative\r\nweed control (such as clean seeds and clean equipment) and where possible,\r\nbiological control. Herbicide resistance in rice weeds, shifts in weed floras and\r\nclimate change pose new and major challenges in the Asian-Pacific region for\r\nincreasing rice productivity further in a sustainable manner. Despite the research,\r\nallelopathic rice accessions or cultivars are yet to make a major impact in rice weed\r\nmanagement in on-farm situations. Over the past 50-60 years, a large corpus of\r\nknowledge has been developed in Asian-Pacific region on both constraints and\r\nopportunities in rice cultivation, including those posed by weeds. Direct-seeding\r\nof rice is now favoured over transplanting by farmers in many countries. To sustain\r\nproductivity and increase rice yields, weed scientists in the region must build on\r\nthe existing knowledge of ecological and biological attributes of rice weeds and\r\napply well established principles of weed management. Whilst herbicides may\r\ncontinue to play an important role, particularly, in managing specific and serious\r\nproblems, such as ‘weedy rice’, over-reliance on herbicides is not likely to be\r\nbeneficial to the Asian-Pacific region in the long run. Instead, attention should be\r\non developing holistic, country-specific, or region-specific rice weed management\r\npackages, integrated with cultivar-specific recommendations. The success of better\r\nmanagement of weeds in rice-field will depend on recognizing that weeds are but\r\nonly one major constraint to increasing rice yields and on applying natural resource\r\nmanagement principles, with appreciation of the broader socio-economic factors\r\nthat influence farmers decision making."^^ .
