‘Horse Hoeing Husbandry’ named famous writing by Jethro Tull (1731) mentioned irst time the word ‘weed’ [1]. Weeds may be considered as plants whose abundance must be over or above a speci ic level can cause major environmental concern [2]. Aldrich and Kremer, 1997 de ined weed as a part of dynamic ecosystem [3]. Plant originated in natural environment and, in response to imposed or natural environments, evolved, and continues to do so, as an interfering associate with crops and activities. Weeds may interfere with the utilization of land and water resources thereby adversely affect human welfare [4]. According to Ancient Indian Literature earth is blessed with diverse lora and every existing plant has their own importance. Some plants are considered unwanted but they may have bene icial properties. Scholars are trying hard to explore the hidden potential of such unwanted plants [5]. Weeds have interactions with other organisms and some of these interactions can have direct effects on the functioning of agro-ecosystem [6]. They serve as an indirect resource for predatory species [7] and it could alternative food sources for organisms that play prominent role in insect control [8]. Weeds have a unique travel history.
