Patent

CA 2269631

Methods and compositions are disclosed wherein exogenous chemicals are applied to plants to generate a desired biological response. One embodiment of the present invention is a plant treatment composition that comprises an exogenous chemical and a first excipient substance. The first excipient substance is an amphiphilic quaternary ammonium compound or mixture of such compounds, having the formula: R8-W a-X-Y b-(CH2)n-N+(R9)(R10)(R11)T-, wherein R8 represents the hydrophobic moiety and is a hydrocarbyl or haloalkyl group having from about 6 to about 22 carbon atoms, W and Y are independently O or NH, a and b are independently 0 or 1 but at least one of a and b is 1, X is CO, SO or SO2, n is 2 to 4, R9, R10 and R11 are independently C1-4alkyl, and T is a suitable anion.

L'invention porte sur des compositions ainsi que sur les techniques afférentes permettant d'apporter à des végétaux certaines substances chimiques afin d'obtenir une réponse de type biologique souhaitée. L'une des réalisations porte sur une composition de traitement de végétaux comprenant une substance chimique exogène et un premier excipient. Ce dernier est un composé d'ammonium quaternaire amphiphile ou un mélange de tels composés, répondant à la formule: R<8>-Wa-X-Yb-(CH2)n-N<+>(R<9>)(R<10>)(R<11>)T<->. Dans cette formule, R<8> représente la fraction hydrophobe ainsi qu'un groupe hydrocarbyle ou haloalkyle comportant d'environ 16 à environ 22 atomes de carbone, W et Y représentent, indépendamment, O ou NH, a et b représentent, indépendamment, un nombre d'une valeur équivalente à 0 ou à 1, mais la valeur de a ou de b doit être de 1; X représente CO, SO ou SO2, la valeur de n est comprise entre 2 et 4, R<9>, R<10> et R<11> représentent, indépendamment, un alkyle comportant de 1 à 4 atomes de carbone et T est un anion approprié.
