The photosystem II inhibitory activity of substituted phenylurea deriv
atives in liverwort photoautotrophically cultured cells was determined
by monitoring chlorophyll fluorescence. Since the inhibitory activiti
es in this assay correlated well with both the Hill inhibitory activit
y in isolated thylakoids and the herbicidal activity against mung bean
plants, this bioassay may be a suitable screening method for photosys
tem II inhibitory herbicides.
