The problem of weed competition in upland rice is of great economic importance as it may cause 50-91% reduction in grain yield. Upland rice is infested with diverse types of grasses, sedges and broad leaved weeds. Weeds usually appear in several flushes during the growing season of rice in uplands. The initial 7-30 days after rice seeding have been found to be critical with respect to crop weed competition. In upland rice, method of crop establishment and tillage operations have great influence on the nature of weed infestation. Integrated weed management is a viable and practical way to manage weeds in upland rice. Integration of indirect methods viz., crop establishment method, row sowing either manually or using seed drills, selection of suitable cultivars (e.g. Vandana, NDR -97, Virendra, Anjali, NDR-118), placement of nutrients below seeds and water management, and direct methods of weed control like, manual, mechanical and chemicals like thiobencarbs, pendemethalin, oxadiazon, oxadiagryl, oxyfluorfen, cyhalofop butyl, anilophos and nitrofen are the major options of weed management on long term basis in upland rice. Most of the herbicides available in market are mostly suitable for transplanted rice, therefore, new broad spectrum post emergence herbicide molecules which will be able to control various flushes of weeds is a necessity as availability of manual labour is becoming scarce in resource poor upland areas.
