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.
