Abstract

Spray of glyphosate, 2, 4-D Na salt and metsulfuron methyl was quite effective against the control of Parthenium hysterophorus. G1yphosate at 0.5 to 1.0%, 2,4-D Na salt at 0.375 and metsulfuron methyl at 0.01% solution gave the 100% control of this weed. 2,4-D at 0.25 and metsulfuron methyl at 0.0025% solution were also quite effective with 93.4 and 95.5% weed control efficiency. The control of P. hysterophorus in pastures and grasslands, may, however, be best made with the spray of either 2,4-D at 0.25 or metsulfuton methyl at 0.005% solution.
