“…"Application of pre-emergence and post-emergence herbicides controlled the weeds effectively resulted in lesser weed dry weight and higher weed control efficiency. Minimum weed dry weight and higher weed control efficiency were recorded with application of pendimethalin 0.5 kg + imazethapyr 50 g ha -1" [14].

A field experiment was conducted during kharif season 2019 and 2020 at research farm of Bihar Agricultural University, Sabour, Bhagalpur to evaluate the effect of different herbicide on weed attributes, yield attributes, yield and nutrient uptake in transplanted rice. The experiment comprised six treatment T1 (pyrazosulfuron ethyl 10 % WP 15 g a.i. ha-1), T2 (pyrazosulfuron ethyl 10 % WP 30 g a.i. ha-1), T3 (carfentrazone ethyl 25 g a.i. ha-1), T4 (carfentrazone ethyl 50 g a.i. ha-1), T5 (weed free) and T6 (weedy) with four replications in randomized block design. The significantly lesser weed density (37.75 No.m-2), weed dry weight (22.87 gm-2), weed index (3.41) and higher weed control efficiency (80.58 %) were recorded with the application of pyrazosulfuron ethyl 30 g a.i. ha-1 at 30 DAT than other treatments. Crop growth parameters (plant height, number of effective tillers, dry matter accumulation), yield attributes (panicle length, effective tillers, number of grains, test weight), nutrient uptake and grain yield were recorded highest in weed free plot (57.88 q ha-1) followed by pyrazosulfuron ethyl 10 % WP 30 g a.i. ha-1. However, least grain yield was recorded under weedy plot. The results suggested that pyrazosalfuron ethyl 10 % WP 30 g a.i. ha-1 were best broad spectrum effective herbicide in order to minimize the diverse weed flora in transplanted rice.
