Disclosed is a method of inhibiting the growth of marine organisms on a marine structure, by applying onto or into the marine structure a halopropargyl quaternary ammonium compound, halopropargyl benzoxazolone compound, or halopropargylhydantoin compound. These compounds may be directly incorporated into the marine structure during manufacture, directly applied to the structure, or applied to the structure by means of a coating.

Halopropargyl compounds as marine antifouling agents

Disclosed is a method of inhibiting the growth of marine organisms on a marine structure, by applying dihydropyridazinone and pyridazinone compounds onto or into the marine structure. These compounds may be directly incorporated into the marine structure during manufacture, directly applied to the structure, or applied to the structure by means of a coating.

Pyridazinones as marine antifouling agents

Disclosed is a method of inhibiting the growth of marine organisms on a marine structure, by applying onto or into the marine structure a phenylamide compound. These compounds may be directly incorporated into the marine structure during manufacture, directly applied to the structure, or applied to the structure by means of a coating.
