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.
一种减少水生杂草和藻类繁盛的方法利用了一类3-苯基-4(1H)-吡啶酮和吡啉硫酮。这些新化合物的特点是在氮上有一个甲基基团,并且通常带有从本文所描述的一类中选择的5-取代基。苯环可能被取代。这些化合物有效地控制水生杂草和藻类,并缓慢杀死植物,使其分解不会耗尽处理水体中的氧气。
