Weed management in lentil with post-emergence herbicides

Abstract

A field experiment was conducted at the Punjab Agricultural University, Ludhiana to study the effect of post-emergence herbicides imazethapyr at 25, 40 and 55 g/ha 25 or 35 DAS and quizalofop-ethyl at 30 and 50 g/ha 25 or 35 DAS along with unweeded check and two hand weedings at 30 and 60 DAS on weeds, growth and yield of lentil (Lens culinaris Medikus). Imazethapyr caused phytotoxicity to lentil but with time the crop recovered. Imazethapyr at 25 as well as 40 g/ha and quizalofop-ethyl at 30 g/ha, both at 25 and 35 DAS, did not adversely affect nodulation. Imazethapyr at 25 as well as 40 g/ha at either 25 or 35 DAS showed promise in improving the grain yield of lentil.
