Field experiment was conducted to study the efficiency of new formulation of pre-emergence herbicide clomazone 50 EC for weed management in HDPS cotton. Clomazone 50 EC was tested at different doses, @ 250, 500 and 750 g a.i. ha-1 and compared with Pendimethalin @ 680 g a.i. ha-1, Pyrithiobac sodium 10 EC and Quizalofop ethyl 5 EC @, cultural; method like one HW at 25 DAS and IC at 50 and 75 DAS, weed free check and other integrated methods. Application of Clomazone 50 EC @ 250 g a.i. ha-1 not showed phytotoxic injury to the germinating cotton and recorded lower weed density and biomass. It has resulted increased seed cotton yield of 38.5 % over unweeded control and higher net returns. Application of Clomazone 50 EC @ 250 g a.i. ha-1 PE fb HW at 25 DAS and IC at 50 and 75 DAS is ideal for better weed control efficiency is good integrated weed control practice.
