Claims10
A method for inhibiting fire blight disease in a plant which comprises
- providing an aqueous medium having a pH of 5 to 8 containing 5-hydroxylysine or a hydrochloride salt thereof in an amount effective to inhibit the growth of E. amylovora and
- applying said medium to a plant having fire blight.
A method for inhibiting the growth of E. Amylovora on a plant at risk of fire blight infection which comprises
- (i) determining whether a plant is at risk of fire blight infection;
- (ii) applying to said plant, if determined to be at risk of fire blight infection, a fire blight control agent comprising an aqueous solution having a pH of 5 to 8 containing at least 0.02 ppm of a hydrochloride salt 5-hydrolysine or at least 25 ppm of a hydrochloride salt 1,4-diamino-2-butanone at a time and in an amount effective to inhibit the growth of E. amylovora on said plant.
An inhibitory growth medium for E. amylovora which comprises an aqueous solution containing at least 0.02 ppm of 5-hydroxylysine or at least 25 ppm of 1,4-diamino-2-butanone.
A fire blight control agent comprising an aqueous solution of 5-hydroxylysine hydrochloride, said solution having a pH of 5 to 8 and containing from 0.2 to 200 ppm of said 5-hydroxylysine hydrochloride in an amount effective to inhibit the growth of E. Amylovora and further comprising streptomycin.
