Blackgram (Phaseolus mungo L.) is one of the important pulse crops grown in India, which belong to the family “Leguminoseae”. It is consumed in various forms as whole or split, husked and unhusked. It is rich in protein, carbohydrate, fat, amino acids, vitamins, and also provides large quantity of green fodder which serves as the nutrition food for the livestock. The number of factor responsible for low productivity (receives low fertilizer input, moisture, pesticides, poor quality seed etc.,) of blackgram, among that factors most important but not recognized factor liable for poor yield due to inadequate weed control. Weed offer severe competition to their crop during early stage of growth and reduce the yield ranges between 27 to 90 per cent due to uncontrolled weed growth. However, different weed control methods like cultural, physical/mechanical, biological and chemical management practices to effectively controlled weeds. Hence, physical/mechanical methods of weed control was achieved by hand weeding or any small weeder (twice) at 20 and 40 DAS not effectively because of high labour wages, continuous rainfall and non-availability at peat period of crop weed competition. Now days, more number of herbicides are available for controlling many weed species very effectively. When in fact, high quantity of herbicides are applied into soil it will contaminating the soil fertility, soil living organisms etc. finally led to damage or affect the life’s of plants, wildlife and even human beings. Keeping these points in view, more population of weeds at later stage of Blackgram pleas for a suitable combination of various weed control techniques to achieve maximum benefits through minimum yield loss and reasonable weed control to the sustainable crop production.
