        abstract = {An experiment was conducted to evaluate the efficacy of different herbicides to control the Cyprus rotundus L. in Bermuda grass (Cynodon dactylon L.) Culcutta grass var. Sel.-1 turf. The experiment consisted different eight herbicides such as Metasulfuron methyl 20%WP 5g/ha (T1), Carfentrazone 40%DF 20g/ha (T2), Atrazine 50%1000g/ha (T3), 2,4-D amine salt 58% SL 580 g/ha (T4), Halosulfuron methyl 75%WG 67.5g/ha (T5), Metribuzin 70%WP 300g/ha (T6), Sulfosulfuron 75%WG 25g/ha (T7), and combinations like Metasulfuron methyl 10% + Chlorimuron ethyl 10%  WP (RM)  45g/ha (T8),  2,4-D amine salt 58% SL 580g/ha + Halosulfuron methyl 75%WG 67.5g/ha (Tank mix) (T9), Carfentrazone 40% DF 20g/ha + Atrazine 50%1000g/ha (Tank mix) (T10) along with hand weeding (T11) and weedy check (T12). Result demonstrated that application of Halosulfuron methyl (T5) exhibited minimum weed density (2.3 /m2) after 80 days.  Likewise, Halosulfuron methyl (T5) showed highest weed control efficiency and the lowest dry matter of Cyperus rotundus L. during different days intervals. Thus, application of Halosulfuron could be used to control weed population of nutsedge grass in turf.},
