Abstract
Esters of 3-nitrophloroglucinecarboxylic acid were found to be active photosystem II (PS II) inhibitors, as were the amides, indicating that , in their structures, the substituted phloroglucinol nuclei themselve s plays a major roles in PS II inhibition. Among the phenylureidoalkyl esters tested, 3,4-dichlorophenylurea compound having two amino hydro gen atoms showed high activities. Optimal activity was associated with compounds in which the oxygen atom and the urea structure in the este r side chain were connected via an ethylene group.
