An experiment was carried out to investigate the efficacy of two herbicides, viz., glyphosate and 2,4- D amine salt at varying doses for the control of the main noxious weeds. The lowest application rate (0.5l per ha of 2,4-D and 2l per ha of glyphosate) of both herbicides gave a control of shoot grow th and drastically reduced the green biomass compared to unweeded plots at different time intervals after the application. There was no re-growth up to nine days after spraying in all treated plots. The highest control of the density of noxious weeds has been obtained with 2,4-D amine salt at the dose of 1.5 l per ha and glyphosate at the dose of 4l per ha in six days after treatment; the reduction rate was more than 85%. Data on green biomass also showed drastic reduction following herbicide application.
