Effet des herbicides à base de glyphosate et fluroxypyr sur les adventices les plus fréquentes dans la culture de l’hévéa (<i>Hevea brasiliensis</i> (H.B.K) (Muell. Arg) à Batouri, Nord du Gabon

Abstract: Tel : + 241 07 23 70 61/+241 07 77 92 12. RESUME L'entretien de la culture d'hévéa est une contrainte pour Olam Rubber pour une meilleure exploitation des arbres. La présente étude vise à évaluer l'efficacité de deux herbicides à base de glyphosate et fluroxypyr sur les adventices les plus fréquents dans la culture d'hévéa à Batouri au Gabon. L'essai était composé de trois blocs d'interlignes, répartis sur trois sites et comportant 16 placettes chacun. Au total, 15 traitements chimiques (T1 à T15) ont été comp… Show more

“…Glyphosate belongs to the glycine family (Ovono et al 2019) and is non-volatile (Singh and Singh 2014). Glyphosate is an herbicide that is highly soluble in water (12 g l −1 ) and insoluble in organic solvents due to a very stable carbon-phosphorus (C-P) bond (Hadi et al 2013).…”

“…Then glyphosate induces the suppression of protein synthesis and secondary metabolites, e.g., flavonoids, lignin inducing cell death (Cao et al 2012;Sviridov et al 2015;Fu et al 2017). The shikimate pathway is found only in microorganisms and plants, never in animals and humans (Samsel and Seneff 2013;Ovono et al 2019), because they do not make their own aromatic amino acids (phenylalanine, tyrosine, and tryptophan), but obtain them from food (Padgette et al 1995) There are two classes of EPSPS: class I are naturally sensitive to glyphosate and occur in plants and many Gram-negative bacteria (e.g., Escherichia coli and Salmonella typhimurium), while class II EPSPS are involved in resistance to glyphosate and are found only in bacteria, including Agrobacterium sp. strain CP4 and Pseudomonas sp.…”
