Rice is an important food crop extensively grown in India. Several factors are responsible for reducing the yield of transplant rice. However, weed infestation is the major threat to productivity of transplanted rice. Weeds by the virtue of their high adaptability and faster growth dominate the crop habitat and reduce the yield potential of the crop. These weeds could be controlled through manual and chemical methods. Manual method is though very common but cost intensive. | 2018 7 4 1660-1669 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 04 2018 Journal homepage http Review Article https Weed Management in Transplanted Rice-A Review Priyanka Kabdal Tej Pratap and Vimal Raj Yadav Department of Agronomy College of Agriculture .

Several factors are responsible for reducing the yield of transplant rice. However weed infestation is the major threat to productivity of transplanted rice. Weeds by the virtue of their high adaptability and faster growth dominate the crop habitat and reduce the yield potential of the crop. These weeds could be controlled through manual and chemical methods. Manual method is though very common but cost intensive. Herbicides when applied alone is although economical but may have limitation of resistance development shift in weed flora etc. Therefore presently there is a need to use high efficacy herbicides in combination coupled with broad spectrum nature to control the complex weed flora in transplanted rice Also the combination of herbicides increase the range of weed control save time and reduce the cost of cultivation. Introduction Rice Oryza sativa L. is one of the most important food crops of India contributing to about 40 of total food grain production. It plays a vital role in food security and livelihood for almost every household. The rice production in India in 2015-16 was MT Directorate of Economics and Statistics 2016-17 . Out of the total 44 Mha area under rice cultivation puddled rice culture occupies 56 Anonymous 2005 . Weeds remove a .
