AbstractWeeds constitute one of the main problems in agriculture. Currently chemical weed control methods dominate and farmers often applied only one type of herbicide based on one mechanism of action (e.g. glyphosate). Worldwide spread of this herbicide contributed to increasing number of glyphosate-resistant weed species. New integrated weed control methods based on a link between biological basic research and weed biology should be implemented. Allelopathy is one of many phenomena influenced on plant interaction among other factors like: nutrients, light, temperature and even humidity and others. Sorghum (Sorghum bicolor L. Moench) has an allelopathic potential and effect on the development of weeds and on the succeeding crops. Sorghum contains many allelochemicals which have a phytotoxic potential against weeds, other crops and finally against each other. Main toxicity caused by sorgoleone and most occurring form is 2-hydroxy-5-methoxy-3-[(Z,Z)-8′,11′,14′-pentadecatriene]-p-benzoquinone. Sorghum realizes allelopathic effect at roots system by drops of sorgoleone. Water extract produced from different parts of sorghum has allelopathic potential and called sorgaab: as a complex of phenols like: gallic, protocatechuic, syringic, vanillic, p-hydroxybenzoic, p-coumaric, and benzoic acids. Allelopathic potential of Sorghum is discussed for weed management and crop improvement.
