Tetrazolinone derivatives having substituted thereon an (optionally substituted) phenoxyphenyl moiety exhibit unexpectedly desirable pre- and post-emergent herbicidal as well as plant growth regulant activity. In addition, herbicidal and plant growth regulatory compositions comprising such novel compounds as well as methods of controlling the growth of weeds and regulating the growth of plants employing such novel compounds are shown. Moreover, a process for producing such compounds is also described.
