An lnvestlqatlon was carrled out to study the effect of different chemicals in combination with ploughing for the control of Cvnodon dactylon at the Agricultural College Farm, Dharwar during the year 1966-67. The herbicides tried were Dalapon, TCA and Paraquat in combination with ploughing. There was mortality of shoots and the reduction in weight of fol laq e, as well as rhizome to depth of 0-30 cm The dessication of the rhizomes occurred upto about 15 to 18 cm depth In the Dalapon treated plot. Dalapon 30 kg per ha with split applications before and after ploughing of the land gave a better control of the weed. It may be possible to control the weed more effectively with spraying of Dalapon about 2 to 3 times during the year
