Broadcast sesame, Pre-emergence herbicides, Seedling vigour index, Phytotoxicity

The study was conducted at S.V. Agricultural College, Tirupati during summer 2015 in a complete randomized design with four treatments consisting of pre-emergence application of pendimethalin 750, oxyflourfen and oxadiargyl 75 g/ha each and control replicated five times. Among the herbicides tested, pre-emergence application of pendimethalin 750 g/ha recorded the highest seedling vigour index followed by oxyfluorfen 75 g/ha in broadcast sesame on sandy loam soils. Pre-emergence application of oxadiargyl 75 g/ha showed phytotoxicity rating of “6” in broadcast sesame.
