Herbicidal activity of Thymbra capitata (L.) Cav. essential oil
2020
The bioherbicidal potential of Thymbra capitata (l.) Cav. essential oil (EO) and its main compound carvacrol was investigated. In in vitro assays, the EO blocked the germination and seedling growth of Erigeron canadensis L., Sonchus oleraceus (l.) L., and Chenopodium album L. at 0.125 µ
Use of Plant Water Extracts for Weed Control in Durum Wheat (Triticum turgidum L. Subsp. durum Desf.)
2020
The use of plant water extracts to control weeds is gaining attention in environmentally-friendly agriculture, but the study of the effect that such extracts may exert on the yield of durum wheat is still unexplored. In 2014 and 2016, the herbicidal potential of several plant water extracts was field tested on durum wheat (cv Valbelice). In 2014, extracts obtained from Artemisia arborescens, Rhus coriaria, Lantana camara, Thymus vulgaris, and Euphorbia characias were used, whereas in 2016 only A. arborescens and R. coriaria were tested as &ldquo
Herbicidal potential of aqueous extracts from Melia azedarach L., Artemisia arborescens L., Rhus coriaria L. and Lantana camara L.
2017
In the search for new strategies for weed management in agricultural systems, a great interest is to use the plant extracts to replace or integrate, chemical weed control. Two experiments were done to test the effects of plant water extracts from Chinaberry (Melia azedarach L.), Tree Wormwood (Artemisia arborescens (Vaill.) L.), Sicilian Sumac (Rhus coriaria L.) and Lantana (Lantana camara L.) on seed germination of Rocket (Eruca sativa Mill.), Rapeseed (Brassica napus L.), Bladderflower (Araujia sericifera Brot.) and Psyllium (Plantago psyllium L). The water extracts (pure and 50% mixtures) from the donor species were applied on seeds of recipient plants. In second experiment in pots, thes…
Identification et caractérisation de candidats d'origine naturelle à action herbicide pour contrôler les adventices
2016
Les produits phytopharmaceutiques (ou pesticides) utilisés aujourd'hui en agriculture sont pointés du doigt pour leurs impacts potentiels sur l’environnement et les écosystèmes et pour les risques qu’ils sont susceptibles d’engendrer pour la santé animale et humaine (Inserm, 2013). Les objectifs majeurs de la thèse sont d’isoler et identifier des microorganismes pathogènes des adventices, et d’acquérir des connaissances sur les mécanismes de l'interaction plante adventicemicroorganismes dans le cadre du développement de bioherbicides pour contrôler les adventices. Outre une analyse bibliographique sur l'état des connaissances relatif aux interactions adventicesmicroorganismes, le travail de…
