PESTICIDE. The present invention relates to a process for obtaining chitosan nanoparticles. Chitosan nanoparticles have an RNA molecule attached to their surface, preferably structured double-stranded RNA (dsRNAst). DsRNAst is selected to have the property of silencing Anthonomus grandis chitin synthase II genes. The invention also features chitosan nanoparticles obtained by said process, its use in pest control, as a pesticide, and a concentrated suspension containing chitosan nanoparticles. |
