A field experiment was conducted at College of Horticulture, Munirabad, Koppal district of Karnataka which falls under Northern Dry Zone of Karnataka, India for two consecutive kharif seasons 2014 and 2015 to find out most suitable and efficient combination of different pre-plant and post-emergence herbicides to control weeds in onion. Experiment was conducted in randomized block design with 12 treatments and three replications consisting of oxyfluorfen were used as pre emergence while oxyfluorfen and fenoxaprop-p-ethyl were used as post emergence and their different combinations. The pre-plant application of oxyfluorfin 23.5 EC@ 240 g a.i/ha followed by post-emergence application of Fenoxaprop – p- ethyl 9 EC@ 270 a.i./ha mixed with oxyfluorfin 23.5 EC resulted in effective control of various broad-leaf and grassy-weeds and recorded lower in total weed density and dry weight of weeds.The same treatments recorded maximum Neck thickness, diameter of the bulb, weight of bulb and Bulb yield (275.8 qt/ha and 271.9 qt/ha ) respectively during both the year due to higher weed control efficiency (88.6 and 89.9 %) over all the other chemical weed control treatments.
