Abstract : Applications of 2 lb/A 2,4-dichlorophenoxy acetic acid (2,4-D) coordinated with alligatorweed flea beetle (Agasicles hygrophila) feeding damage resulted in the deterioration of subsurface mats of alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.). The constant pressure on the surface alligatorweed growth, when using the integration method, appeared to deplete the subsurface carbohydrate reserves in alligatorweed stems. The integrated control in laboratory and small plot experiments has yielded a greater reduction of floating alligatorweed mats than is attainable with either agent alone. (Modified author abstract)
