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 β 1-3 glucans composed of 3 to 250 monosaccharide units and a vehicle, wherein the effective amount of oligo β 1-3 glucans in the composition does not directly stimulate natural defensive reactions of plants when the pathogenic agent is absent.
Claims17
A composition useful in potentiating and stimulating natural defensive reactions of plants to a pathogenic agent, comprising a vehicle and one or more oligo β(1-3) glucans with an average degree of polymerisation from 3 to 15 and composed of from 2 to 30 monosaccharide units at a concentration from 1 mg/l to 20 mg/l.
A method to potentiate and stimulate in an agronomically useful plant natural defense reactions which are normally developed by the plant when the plant has first contact with a pathogenic agent, the method comprising applying to the plant before the first contact with the pathogenic agent, a composition comprising one or more oligo β(1-3) glucans with an average degree of polymerisation from 3 to 15 and composed of from 2 to 30 monosaccharide units and a vehicle, the one or more oligo β(1-3) glucans being present in the composition at a concentration from 1 mg/l to 20 mg/l.
