Pre emergence herbicide application and handweeding for effective weed management inirrigated kodo millet (Paspalum scrobiculatum L.)

Abstract

Field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during kharif 2014 to evolve weed management through herbicide and hand weeding for higher productivity in kodo millet. The experiment was laid out in randomized block design with three replications. The treatments comprised of different herbicides (pendimethalin, isoproturon and bensulfuron + pretilachlor) with or without hand weeding and mechanical weeder weeding. Pre emergence application of isoproturon 750g/ha followed by hand weeding on 40 days after sowing can keep the weed density and dry weight below the economic threshold level and increase the weed control efficiency under irrigated kodomillet without any phytotoxicity to the crop.
