Des r\u00e9sultats encourageants<\/strong><\/h2>\n

Le Centre de coop\u00e9ration internationale en recherche agronomique pour le d\u00e9veloppement (CIRAD) m\u00e8ne r\u00e9guli\u00e8rement des exp\u00e9riences sur les sargasses et vient de r\u00e9v\u00e9ler que \u00ab\u00a0ces algues pourraient […] devenir une source d’innovation pour une agriculture plus durable\u00a0\u00bb.<\/p>\n

Dans le cadre de ses travaux sur l\u2019innovation dans le domaine de l\u2019agro\u00e9cologie, le CIRAD aurait obtenu des r\u00e9sultats tr\u00e8s concrets et encourageants. \u00ab\u00a0Le projet SAVE-C a ainsi permis d’\u00e9valuer le potentiel insecticide des extraits de ces algues contre Bemisia<\/em> tabaci<\/em> et d’explorer leur utilisation comme biopesticides naturels. Les r\u00e9sultats obtenus mettent en \u00e9vidence des perspectives prometteuses pour le d\u00e9veloppement de nouvelles solutions de biocontr\u00f4le d’origine naturelle\u00a0\u00bb, souligne le Campus agro-environnemental cara\u00efbe (CAEC), dans une annonce sur les r\u00e9seaux sociaux.<\/p>\n

Les scientifiques du CIRAD tentent d\u2019extraire les compos\u00e9s des sargasses afin d\u2019en trouver une utilisation concr\u00e8te dans le domaine de l\u2019agro\u00e9cologie. Apr\u00e8s \u00e9tude, les sargasses pourraient avoir une utilit\u00e9 tr\u00e8s op\u00e9rationnelle et servir de bioinsecticide et de biopesticide d\u2019origine naturelle, permettant un biocontr\u00f4le. Ainsi, il a \u00e9t\u00e9 observ\u00e9 \u00ab\u00a0jusqu\u2019\u00e0 70 % de mortalit\u00e9 observ\u00e9e chez les aleurodes adultes\u00a0\u00bb, \u00ab\u00a0une r\u00e9duction de la ponte\u00a0\u00bb et \u00ab\u00a0une perturbation du d\u00e9veloppement des larves\u00a0\u00bb.L\u2019applicabilit\u00e9 de ces r\u00e9sultats reste encore \u00e0 d\u00e9velopper mais les recherches se poursuivent tant les enjeux sont importants. \u00ab\u00a0Des recherches compl\u00e9mentaires sont encore n\u00e9cessaires, mais ces premiers r\u00e9sultats ouvrent des perspectives prometteuses pour le d\u00e9veloppement de solutions de biocontr\u00f4le d’origine naturelle dans les territoires carib\u00e9ens\u00a0\u00bb, ajoute le CAEC.<\/p>\n
