The experiment was conducted during 2022-23 at Instructional Farm, College of Agriculture. Jodhpur, Rajasthan to evaluate the impact of different post-emergence herbicides on weed dynamics and mungbean productivity. Field experiment was laid out in randomized block design (RBD) with ten treatment combinations and replicated thrice. The treatments taken in the investigation were W1- Weedy check, W2- Weed free, W3- Imazethapyr 55 g/ha, W4- Fluazifop-p-butyl 250g/ha, W5- Pendimethalin + imazethapyr 800 g/ha, W6- Imazethapyr + imazamox 70 g/ha, W7- Propaquizafop + imazethapyr 83.3 g/ha, W8- Aciflourfen sodium + clodinafop- propargyl 210 g/ha, W9- Fomesafen + fluazifop-p-butyl 220 g/ha, W10-Quizalofop ethyl 60 g/ha. Digera arvensis L., Phyllanthus niruri L., Dactyloctenium aegyptium L., Portulaca oleracea L., were the most dominant weeds among identified dicot weed species whereas important monocot weeds included Cynodon dactylon L., and Dactyloctenium aegyptium L., in the field. Post-emergence application of fomesafen + fluazifop-p-butyl 220 g/ha (W9) followed by treatment sprayed with sodium acifluorfen + clodinafop-propargyl 210 g/ha (W8) showed significantly greater plant height & efficacy in reducing total weed density. Ready mix application of (W9) 220 g/ha can be suggested owing to higher seed yield and profits for farmers while lowering the herbicide dose and expenses in involved in manual weeding and as compared to rest of the treatments tested during field experimentation.
