STUDIES ON CHLOROSIS-INDUCING ACTIVITIES AND PLANT-GROWTH INHIBITION OF BENZOPHENONE DERIVATIVES
Agricultural and biological chemistry(1979)
摘要
Some benzophenones substituted with methyl, methoxy, hydroxy or halogen groups inhibited growth and induced chlorosis in various plants. The structure activity relationships about the chlorosis-inducing activity and the growth inhibitory activity of the 3-methyl-benzophenones were well expressed by use of hydrophobic contant π, and Hammett’s σ. The highest selectivity for phytotoxic activities against barnyardgrass and the rice plant was with 3,3′-dimethyl-4-methoxybenzophenone (Methoxyphenone).
