A method of controlling target aquatic microorganism pest populations by exposing the target population to an effective amount of an aquacidal compound. The aquacidal compounds are selected from the group consisting of quinones, anthraquinones, naphthalenediones, quinine, warfarin, coumarins, amphotalide, cyclohexadiene-1,4-dione, phenidione, pirdone, sodium rhodizonate, apirulosin and thymoquinone. The method is particularly effective for treating ballast water of ships or other enclosed volumes of water subject to transport between or among geographic areas to control the relocation of plants, toxic bacteria, and animals contained in the water.

The invention claimed is: 1. A method for killing a target population of mollusk pests in a ballast water tank hosting said population comprising the step of adding to said ballast water tank an amount that is sufficient to kill said target population of an aquacidal compound selected from the group consisting of 1,4-benzoquinone, 2,5-dihydroxy 3,6-dinitro p-benzoquinone, 2,6-dimethoxy benzoquinone, 3-hydroxy-2-methoxy-5-methyl-p-benzoquinone, 2-methylbenzoquinone, tetrahydroxy-p-benzoquinone, and 2,3-dimethoxy-5-methyl-1,4-benzoquinone or mixtures thereof. 2. The method of claim 1, wherein said mollusk pests are selected from the group consisting of mussels, clams and snails. 3. The method of claim 1, wherein said mollusk pests are selected from the group consisting of zebra mussels and Asiatic clams. 4. The method of claim 1 wherein said pests are exposed to said aquacidal compound for a period of time sufficient to kill said pests. 5. The method of claim 4 wherein said pests are exposed to said aquacidal compound for a period of time within the range of 1-96 hours. 6. A method for controlling a population of target aquatic pest by applying an aquacidal compound to water in a ballast water tank that is infected with said aquatic pest, wherein said aquacidal compoumd is applied in an amont that is effective to kill said population and is a beazoquinone having the formula: where: R1 is hydrogen, methyl, hydroxy or methoxy group; R2 is hydrogen, hydroxy, methyl, methoxy or--NO2 group; R3 is hydrogen, hydroxy, methyl or methoxy group; and R4 is hydrogen, methyl, methoxy, hydroxy, or--NO2 group.
