Fuente: WIPO "tomato" Use of an extract of at least one agarophyte red alga as a nematocidal agent and method for controlling phytopathogenic nematodes
Use of an aqueous liquid product resulting from extraction by an alkaline aqueous solution of at least one agarophyte red alga of the Gelidiaceae family, such as Gelidium sesquipedale, as an agent for controlling phytopathogenic nematodes. The extraction product is in particular the aqueous phase obtained by extracting the said at least one agarophyte red alga by an alkaline aqueous solution, followed by filtration to recover the said aqueous phase, which may then have been concentrated, dehydrated or freeze-dried, and then redissolved in water for application.
