Abstract
A method of reducing the vigor of aquatic weeds and algae makes use of a class of 3-phenyl-4(1H)-pyridones and pyridinethiones. The new compounds are characterized by a methyl group on the nitrogen, and usually bear a 5-substituent chosen from a class which is described herein. The phenyl ring may be substituted. The compounds effectively control aquatic weeds and algae, and kill the plants slowly, so that their decomposition does not deplete oxygen in the treated body of water.
