A field investigation entitled “Effect of different weed management practices on weed dynamics of gladiolus (Gladiolus grandiflorus L.) cv. Arka Pratham” was carried out at the Experimental Field, Department of Floriculture and Landscaping, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Rabi 2024-25. The experiment consisted of fifteen treatments for weed control: Treatments viz. Pendimethalin PE (960 g/ha), Pendimethalin PE fb imazethapyr + imazamox (960 fb 70 g/ha) at 30 DAP (PoE), Pendimethalin PE fb oxyfluorfen (960 fb 200 g/ha) at 30 DAP (PoE), Pendimethalin PE fb propaquizafop + imazethapyr (960 fb 125 g/ha) at 30 DAP (PoE), Pendimethalin PE fb hand weeding at 30 DAP, Pendimethalin PE fb hand weeding at 30 and 60 DAP, Diuron PE (75 g/ha), Diuron PE fb imazethapyr + imazamox (75 fb 70 g/ha) at 30 DAP (PoE), Diuron PE fb oxyfluorfen (75 fb 200 g/ha) at 30 DAP (PoE), Diuron PE fb propaquizafop + imazethapyr (75 fb 125 g/ha) at 30 DAP (PoE), Diuron PE fb hand weeding at 30 DAP, Diuron PE fb hand weeding at 30 and 60 DAP, three hand weeding at 20, 40 and 60 DAP farmers practice, plastic mulch and weedy check. The field experiment was laid out in Randomized Block Design (RBD) with three replications. The plots treated with pre-emergence herbicides i.e. Pendimethalin, diuron and hand weeding significantly reduced the weed population at early stage of crop growth as compared to weedy check and other treatment. Weed population and dry weight of weed accumulation were significantly reduced by plastic mulch and Diuron PE fb Propaquizafop + Imazethapyr PoE at 30 DAP and Pendimethalin PE fb propaquizafop + imazethapyr PoE at 30 DAP, while the highest weed infestation was observed in the weedy check. weed control efficiency was highest in Diuron PE fb Propaquizafop + Imazethapyr PoE at 30 DAP closely followed by plastic mulch across 30, 60 and 90 DAP, whereas weedy check recorded zero weed control efficiency.
