Abstract
A pot experiment was conducted to evaluate the herbicidal potential of Chwastox and Buctril Super against noxious weed Parthenium hysterophorus L. The recommended doses (R) of Chwastox (4 ml L-1 ) and Buctril Super (2.5 ml L-1 ) as well as dilutions @ ¾ R, ½ R and ¼ R were sprayed on pot grown P. hysterophorus plants after 2, 5 and 10 weeks of sowing corresponding to early vegetative, preflowering and maturity stages, respectively. All the employed dosages of Buctril Super killed the target weed at all the three growth stages within 2 days of spray. Chwastox, however, was found to be a slow active herbicide in this case and effective control was delayed up to 7 days.
