ABSTRACT

Field experiment to study the efficiency of different herbicides to control the weeds in fingermillet was conducted during two seasons of kharif 2014 and 2015 in sandy loam soils at Agricultural Research Station Perumallapalle. Results from two consecutive seasons revealed that among different weed management practices,pre- emergence application of oxyfluorfen 0.2 kg a.i /ha + one hand weeding at 20 DAP (1.56) followed by pendimethalin 0.5 kg a.i/ha+ one hand weeding at 20 DAP realized higher benefit cost ratio (1.52) compared to hand weeding. Post emergence application of 2, 4-D Sodium salt @ 0.8 kg a.i /ha at 20 days after planting realized higher cost benefit ratio (1.91). Post-emergence application of bispyribac sodium @ 20 g a.i/ ha showed phototoxicity on crop growth.
