The present invention relates to the use of a quaternary ammonium glycoside surfactant as an adjuvant for fertilisers or pesticides, such as herbicides. The surfactant contains at least one hydrocarbon group with 6-24 carbon atoms and at least one quaternary ammonium group where at least one substituent is an alkyleneoxy containing group which is connected to a saccharide residue by a glycosidic bond. Also compositions containing pesticides or fertilisers are described. These quaternary ammonium glycoside surfactants have an essentially improved biodegradability. They also improve the uptake and efficacy of fertilisers and herbicides.
L'invention concerne l'utilisation d'un tensioactif à base de glycoside et d'ammonium quaternaire, en tant qu'adjuvant, dans des engrais ou pesticides, tels que des herbicides. Ce tensioactif contient au moins un groupe hydrocarbure comportant 6 à 24 atomes de carbone, et au moins un groupe d'ammonium quaternaire dans lequel au moins un substituant est un groupe qui contient alkylène-oxy et est relié à un reste saccharide par une liaison glycoside. L'invention concerne également des compositions contenant des pesticides ou des engrais. Ces tensioactifs à base de glycoside et d'ammonium quaternaire possèdent une biodégradabilité très améliorée, et ils améliorent également l'assimilation et l'efficacité des engrais et herbicides.
