  • Patent number: 6387847
    Abstract: The present invention provides a method to potentiate and stimulate natural defensive reactions of plants to a pathogenic agent. The method comprises application to plants of a composition comprising an effective amount of one or more oligo &bgr; 1-3 glucans composed of 3 to 250 monosaccharide units and a vehicle, wherein the effective amount of oligo &bgr; 1-3 glucans in the composition does not directly stimulate natural defensive reactions of plants when the pathogenic agent is absent.

  • Patent number: 5703009
    Abstract: A method for improving the germination of seeds or the growth of bulbs in which, prior to planting, the seeds or bulbs are placed into contact with gaseous ozone and the residual moisture content of the seeds or bulbs is adjusted before or simultaneously with the ozone contact to a value in the range of 5 to 60% by weight.
