Title: Applied allelopathy in weed management: an update
Abstract: Allelopathic phenomenon perpetuating in nature is of considerable significance, which has gained even more importance these days. Field applications of allelopathy have attracted the attention of scientists as an alternate to weedicide use. In this chapter, allelopathy development and its application for weed management have been reviewed over the last two decades. Allelochemicals of potential herbicidal activity, developed bioherbicides from plants or microorganisms, plant species of allelopathic properties and the inflicted weeds, allelopathy forms, and methods of application have been documented. Some implications on allelopathic crops and their utilization in agricultural system, and positive and negative impact of allelopathy on cultivated crops and weeds have also been evaluated. Constraints associated with allelopathy application for weed management in the field, results obtained and conclusions drawn based on certain findings are discussed. Prospects of allelopathy as a possible strategy for weed management, for development of eco-friendly bioherbicides, and its importance for sustainable agriculture are also discussed. Some recent findings on molecular aspects of allelopathic species and the genetic basis of produced allelochemicals have been described. [J. R. Qasem (2012).
