A field experiment was conducted for two consecutive years (2017 -18 and 2018-19) at Agricultural Research Station, Jangamaheswarapuram, Guntur Dist. Andhra Pradesh, India. The experiment consisted of nine treatments laid out in a complete randomized block design with four replications. The results revealed that Triafamone18.52 SC doses at a rate of 100 g a.i. ha^-1 (T₅) and 50 g a.i. ha^-1 (T₄) at the 2-3 leaf stage of weed were effective in controlling all the weeds and recorded significantly (P<0.05) lesserdry weight of weeds over the control during the study.
