  • Patent number: 5639794
    Abstract: Methods and compositions employing saponin as synergist in combination with a natural product, such as an aromatic 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 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 is also provided.
