Patent

CA 2196973

Methods and compositions employing saponin in combination with a natural product, such as flavonoid aldehyde, are provided for controlling the colonization and/or growth of plant and animal pathogens, such as fungi, insects, arachnids and non-aquatic mollusks, on materials such as plants, plant parts and agricultural products before, during, after harvest and/or processing. The invention finds use in treating agricultural crops for pathogenic organisms which colonize the surfaces of plant parts and tissues and controlling the level of toxic metabolites present in consumable products derived from plant materials, as well as reducing the health risk associated with their consumption. A method of employing saponin to kill nematodes also is provided.

On décrit des procédés ainsi que des compositions utilisant de la saponine en combinaison avec un produit naturel, tel qu'un aldéhyde de flavonoïde, pour lutter contre la colonisation et/ou la croissance de germes pathogènes végétaux et animaux, tels que des champignons, des insectes, des arachnides et des mollusques non aquatiques, sur des matières telles que des plantes, des parties de plantes, des produits agricoles, avant, pendant, après la récolte et/ou un traitement. L'invention est notamment utile pour traiter les cultures agricoles contre les organismes pathogènes qui colonisent les surfaces de parties et tissus de plantes, et pour limiter le niveau de métabolites toxiques présents dans des produits consommables dérivés de matières végétales, de même que pour réduire le risque sanitaire lié à leur consommation. On décrit également un procédé d'utilisation de saponine pour tuer des nématodes.
