As pigeonpea is long duration crop, many flushes of weed germinate at the later stages which compete with the crop. It is therefore, essential to use the post emergence herbicides in conjuction with pre emergence herbicides for the effective control of weeds. Presently, imazethapyr is a very effective post emergence herbicide for controlling broad leaf weeds in kharif pulses including pigeonpea but its weed control efficacy has not been judged in combination with propaquizafop for wide spectrum weed control in different parts of the country including Jabalpur an experiment was conducted at Product Testing Unit, Department of Agronomy, JNKVV, Jabalpur during kharif season of 2015. Weedy check had the highest weed biomass and it was reduced significantly when weeds were controlled either chemically or mechanically. Among the herbicidal treatments, post emergence application of propaquizafop + imazethapyr at g/ha or higher rate (100+100 g/ha) arrested the weed biomass production remarkably and proved superior to alone application of propaquizafop (50, , 100 and 125 g/ha), fenaxaprop-p-ethyl (100 g/ha) and imazethapyr (100 g/ha). | To find out the suitable post emergence herbicides for controlling weeds in pigeonpea
