“…The effectiveness of the extracts varied with their concentration and test plants. These results are supported by others studies which noted that the inhibitory activity depended on extract concentration (Parvez et al, 2004, Shunjie et al, 2008, Moosavi et al, 2011Mousavi et al, 2013). Differences in the biochemical and physiological nature of test plants may be responsible for inhibitory effects of the extracts (Sodaeizadeh et al, 2009).…”

“…The results showed extracts had greater effect on seedling growth rather than on germination which agrees with findings of Konstantinović et al [65] who concluded that effect of allelochemicals is more pronounced on the growth of seedlings [66]. Several investigations indicating the allelopathic or phytotoxic determine of aqueous extracts of plants contain Sorghum bicolor [67], Argemone mexicana [68], Carum carvi [21], Euphorbia thiamifolia [69], Chrysanthemum coronarium [70] and Vicia faba [71]. All these investigations indicated the discharge of phototoxic chemicals during the preparation of aqueous extracts.…”

Antibacterial activity; Allelopathy verbena is known to have antispasmodic, antipyretic, sedative, digestive, antimicrobial, local analgesic, and antioxidant activities [13,14]. Due to these properties, lemon verbena represents a huge market potential for herbal preparation and of essential oil extraction [15]. Although plant secondary metabolites are generally associated with plant defense against herbivores and pathogens, these unique compounds can be involved in a broad array of ecological functions [16]. Phenolic compounds are one of the largest groups of secondary metabolites, consisting of four main groups divided according to the number of phenol rings and the structural elements that bind those rings, including flavonoids, phenolic acids, tannins, stilbenes and lignans [17]. Indeed, some secondary metabolites such as benzoxazinoids are regarded as natural pesticides against pathogens, microorganisms, fungi, insects, and weeds [18]. The ubiquitous use of agrochemicals has resulted in negative impacts on human health and the environment. The use of the biological activity of plant extracts against certain pests of crops remains an environmental friendly alternative. Allelopathy is a phenomenon whereby secondary metabolites synthesized by microorganisms or plants may positively

“…Sorghum, also a monocotyledonous crop, is a notable example of allelopathic activity, producing toxic compounds not only in the leaf material but also in the roots (Moosavi et al, 2011;Rice, 1984;Weston et al, 2013;Yarnia et al, 2009). Therefore, it follows that if the sugarcane leaves and bagasse have allelopathic activity (Webber et al, 2017b), that the roots may also be allelopathic.…”

Allelopathy, the chemical interaction between plants, may result in the inhibition of plant growth and development, which can include compounds released from a crop that adversely impact weed species. The objective of this research was to determine the allelopathic impact of sugarcane (Saccharum officinarum) field residue and root water extracts on seed germination of three weed species. Red morningglory (Ipomoea coccinea L.), redroot pigweed (Amaranthus retroflexus L.), and spiny amaranth (Amaranthus spinosus L.)] seeds were treated with five extract concentrations (0, 12.5, 25, 50, and 100 g/L) from either sugarcane field residue or sugarcane root extracts. The field residue and roots were from sugarcane variety 'HoCP 96-540' plant cane. Germination generally decreased with increasing sugarcane field residue extract concentrations in the three weed species tested. At the highest residue concentration (100 g/L), red morningglory, redroot pigweed, and spiny amaranth germination decreased by 29%, 17.5% and 80.5%, respectively. Germination generally decreased with increasing sugarcane root extract concentrations in red morningglory and redroot pigweed, but not with spiny amaranth. The highest root concentration (100 g/L) decreased red morningglory and redroot pigweed germination by 19.5% and 18.5%, respectively. This research provides the first bioassay demonstrating that sugarcane root extracts have allelopathic activity, and specifically in respect to red morningglory and redroot pigweed germination. Future research should investigate the allelopathic compounds present in the sugarcane field residue and roots, determine if the same allelopathic compounds are present and in similar concentrations among other sugarcane varieties, and further examine which weed species may be susceptible to the allelopathic compounds present in sugarcane roots.
