“…The fact besides the high amount of extraction with water solvent may be due to the presence of water-soluble polar compounds present in plant according to the principle "like dissolves like". This result is in coherence with the earlier findings reported by Poudel (2004) for Artemisia dubia and Suwal (2006) for Chromolaena odorata.…”

“…Inhibition was higher for leaf extract compared to stem and root extract and this may be because of repository inhibitory compounds present in leaf. This result is comparable to earlier findings that reported more harmful effect of leaf extract than shoot and root extract (Poudel 2004;Suwal 2006).…”

“…Lydon et al (1997) has suggested that other molecules may also be involved in the phytotoxic effect as they found aqueous extract devoid of artemisinin to be equally phytotoxic as compared to treatment with artemisin. Besides, flavonoids and phenolics (known group of allelochemicals) are also reported from some of Artemisia spp (Suleimenov et al 2005;Modallal & Al-Charchafchi 2006). These suggest A. dubia to be repository of both polar and non polar allelochemicals that could be exploited for the control of ragweed and further provide conformity to its herbicidal potentiality.…”

Allelopathic effect of aqueous (leachate) and solvent extract (hexane, chloroform, methanol and water) of leaf, stem and root of donor plant Artemisia dubia was studied on germination and seedling vigour of Parthenium hysterophorus. Extraction and quantification of different parts in different solvent was done by percolation method. Bioassay was performed by allowing P. hysterophorus seed to germinate in Petri dishes (for solvent, aqueous) in laboratory condition against varied concentrations of prepared extracts of A. dubia. All the tested extract (aqueous, solvent) from different plant parts significantly checked the germination of P. hysterophorus in higher concentration with the effect being more pronounced from the leaf of A. dubia. Linear growth of root and shoot of P. hysterophorus was also checked significantly with increasing concentration of tested plant extract. The order of allelopathic influence was leaf > stem > root in all the cases and it was concentration dependent. Length of root was retarded while stem length experienced no effect, sometime elongation (stem and root extract of leachate, stem extract of hexane and chloroform). These results provide ample evidence that allelopathic potential exist in A. dubia and this can be exploited for the control of P.hysterophorus.Journal of Institute of Science and Technology Volume 22, Issue 2, January 2018, Page: 127-128

“…La tendance de diminution en hauteur des mauvaises herbes des parcelles traitées peut être expliquée par un pouvoir réducteur de la croissance du thé de compost. Cette capacité de réduction de la croissance lui aurait été conférée par l'espèce de base du compostage, Chromoaena odorata L., par diffusion des composés chimiques allélopathiques hydrosolubles qu'elle contient (Suwal et al, 2010). Mieux, la valeur moyenne de poids frais des mauvaises herbes est inversement proportionnelle à la dose du thé de compost.…”

REMERCIEMENTSLes auteurs remercient le Centre Régional de Recherche et d'Education pour un Développement Intégré (CREDI-ONG) pour avoir financé cette étude. RESUMELa transition agroécologique en cours dans le monde nécessite le développement des alternatives de production saine, notamment concernant la gestion des nuisibles de cultures. La présente étude vise à évaluer en milieu réel, l'effet herbicide des composés allélopathiques de Chromoleana odorata sur les mauvaises herbes à travers son thé de compost. Le dispositif expérimental est un bloc aléatoire complet avec quatre répétitions. Les données collectées ont porté sur la diversité, la taille et la biomasse aérienne des mauvaises herbes. De l'analyse de variances effectuée, il ressort que le thé de compost a significativement (p ˂ 0,05) réduit la taille et la biomasse aérienne des mauvaises herbes sans pour autant affecter leur richesse spécifique. Le thé de compost de C. odorata a ainsi réduit l'enherbement et serait donc une piste potentielle pour le développement de biointrants en agroécologie. Effect of Chromoleana odorata L. compost tea on the development of weeds ABSTRACTThe ongoing agroecological transition needs the development of alternative methods of production as far as the pests management is concerned. This study aims to assess on farm the herbicide effect of Chromoleana odorata L. allelochemicals through the compost tea. The experimental design is a Fisher block with four replications. The data collected relate to the diversity, the height and weight of weeds. After performing the ANOVA, we can realize that the compost tea has significantly (p ˂ 0.05) reduced the height and the weight of weeds without affecting their diversity. The compost tea of C. odorata has thereby controlled the weeds and is a potential source of bio inputs in agroecology.

“…Choromolaena odorata has been found to suppress indigenous grassland and savannah vegetation through physical smothering . There have also been many findings showing that substances released by C. odorata and aqueous extracts of the plant remarkably influence the seed germination and growth of neighboring plants (Hu & Zhang, 2013;Suwal et al, 2010).

Invasive plant species have been commonly implicated to cause loss in plant species diversity. Attention had however not been paid to the effects of these species loss on the soil microbiome. A study was conducted in 18 farmers’ fields within three states in southwestern Nigeria to examine the effect of Siam weed (Chromolaena odorata) invasion on native plant diversity as well as on the rhizosphere microbial population using randomized complete block design. Results indicated significant losses in plant species diversity and reduction in density per square meter compared with adjacent non infested fields. Results further showed C. odorata invasion exerted diverse influence on soil microbial population. Relationships were subsequently established among plant density, species diversity; and soil microbial population. Further studies were also recommended to accommodate more microbiological indices.
