Abstract

This study was conducted to determine the efficacy of metsulfuron applied alone or tank-mixed with triclopyr or paraquat on woody borreria (Hedyotis verticillata Lam.) prior to the development of woody tissues (lignification) under glasshouse and/or field conditions. The glasshouse study indicated that of the 18 treatment combinations, 10 were antagonistic while seven were additive and one was synergistic, with plant fresh weight reduction ranging from 53-93%. The field study demonstrated that metsulfuron plus paraquat at 0.1 + 140, 0.5 + 70 and 0.5 + 140 g a.i. ha-1 provided more than 95% control of H. verticillata while metsulfuron plus triclopyr at 0.5 + 20, 0.5 + 40 and 0.2 + 80 g a.i. ha-1 provided less than 65% control of H. verticillata.
