Patent ID: 8377934

Claim:
A method of preventing or treating an oomycete infection in an aquatic organism, the method comprising the step of contacting the aquatic organism with an effective amount of at least one 4,4′-bis-(1,3,5-triazinylamino)stilbene-2,2′-disulfonic acid derivative of Formula (I): wherein R 1 and R 2 are the same or different and are each independently selected from the group consisting of SO 3 H, SO 3 Na, SO 3 K, SO 3 NH 4 and H; R 3 to R 10 are the same or different and are selected from the group consisting of H; linear or branched C 1 -C 6 alkyl; linear or branched C 2 -C 6 alkenyl, wherein said alkyl or alkenyl are each independently unsubstituted or substituted with a hydroxyl, carboxyl, or carboxamide group; phenyl; and phenyl substituted with R 1 or R 2 wherein R 1 and R 2 are as defined above; or one or more of R 3 and R 4 , R 5 and R 6 , R 7 and R 8 or R 9 and R 10 , together with the nitrogen to which they are attached, form a heterocyclic ring which can further comprise one or more additional heteroatoms selected from N, O and S; and salts, hydrates, solvates and polymorphs thereof; thereby preventing or treating the oomycete infection in said aquatic organism.
