But weed is the measure problem for declining yield of crops day by day. A weed can be thought of as any plant growing in the wrong place at the wrong time. Weeding is an important but equally labor incentive agricultural unit operation. Weeding accounts for about 25 of the total labor requirement 900-1200 man h ha during a cultivation season Silas et al. 2015 . In India reduction in yield due to weed alone is estimated to be 16-42 depending on crop and location and involves 1 3rd. of the cost of cultivation Goel. et al. 2008 . The weed should be controlled and eliminated at their early stage. Depending upon the weed density 20-30 percent loss in grain yield is quite usual which might increase up to 80 per cent if adequate crop management practice is not observed. Delay and negligence in weeding operation affect the crop yield up to 30 to 60 percent Rajvir Yadav 2007 . In India about billion rupees are spent every year
