“…Thousands of allelopathic substances have been isolated from plants and their chemical structure has been determined; however, the MeA has only been elucidated for a limited number of allelochemicals (Vyvyan 2002). In a review that highlighted 30 phytotoxins produced by microorganisms and plants, 23 different MeA were identified (Duke et al 2002).…”

Allelopathy determines the dynamics of plant species in different environments. Understanding this biological phenomenon could help to develop applications in both natural and agricultural systems. This review summarizes the genetic and environmental characteristics that control the production and release of allelochemicals in agroecosystems. This study highlights the current understanding of the environmental changes caused by allelochemicals and summarizes the knowledge about the mechanisms of action of these compounds. Finally, it reviews novel applications of allelopathy in agricultural production systems, including the role of allelochemicals in consortia and their potential use in no-tillage cropping systems through cover crops or mulches.ARTICLE HISTORY

“…In recent times number of breahthrough work has been done in respect of biopesticides with particular reference to botanicals, microbial pesticides, pheromones, IGR, plant growth regulators, and new more promising crop protection molecules. A detailed review of naturally occurring bioactive crop protecting chemicals has been discussed by Vyvyan [2] and Dyan [3,4]. However, in today's perspective, there is a strong desire to use "greener" chemistry to produce more toxicologically and environmentally benign pesticides and natural products.…”

Increase in productivity is directly related with increase pesticide consumption. So there is a strong desire to use "greener" chemistry to produce more toxicologically and environmentally benign pesticides and natural products. In this present study, a comparison was made to evaluate the phytotoxicity potential of first cleanup fractions obtained from sequentially extracted solvent (ethyl-acetate, methanol) extracts of Parthenium hysterophorus L. (aerial parts) in vitro through bench-top seed germination assay (Vigna radiata L.). One-way analysis of variance (ANOVA) followed by Duncan's multiple range test (DMRT) were done for statistical analysis of the data. The study reveals that germination, growth and vigour was significantly (P<0.05) reduced by ethyl-acetate and methanol fractions. A significant changes in soluble and insoluble sugar content, protein, amino acid content and cellular metabolic activity was aslo observed by 1F3, 1F4, 1F6, and 1F9 fractions. The present study concluded that phytotoxicity of four fractions (1F3, 1F4, 1F6, and 1F9) from ethylacetate and methanolic crude extracts of Parthenium hysterophorus could be exploited as potential bioherbicide for future weed management programme and the development of bioherbicide for commercial use.

“…Antimicrobial resistance developing in pathogens towards antibodies has leads to treatment failure and necessitates the search for new antimicrobials (Otimentin et al 2008). Plants derived compounds contribute a lot in fight against pathogens (Vyvyan 2002). Various plant extracts can serve both as potential antimicrobial crude drugs as well as a source of new anti-infective agents (Rios, 2005).…”
