Abstract :Parthenium hysterophorus L., is a noxious annual weed rapidly spreading across the cropped and non-cropped and has become a major threat to cropped and noncropped areas. Field experiments were conducted to evaluate the efficacy of different herbicides against parthenium weed at its mixed population of different growth stages in non-cropped area. The experiments were laid out in accordance with RCBD with three repeats of ten treatments. Herbicides used in the experiments were RoundUp 54SL insert ignore into journalissuearticles values(glyphosate); @ 2.5 l ha-1, Maxtrol 38SC insert ignore into journalissuearticles values(atrazine); @ 1200 ml ha-1, Sencor 70WP insert ignore into journalissuearticles values(metribuzin); @ 625 g ha-1, Gesapax combi 80WP insert ignore into journalissuearticles values(ametryne+atrazine); @ 2.5 kg ha-1, Clean Core 50EC insert ignore into journalissuearticles values(acetochlor); @ 250 ml ha-1, Gramaxone 20SL insert ignore into journalissuearticles values(paraquat); @ 1250 ml ha-1, Stomp 330 EC insert ignore into journalissuearticles values(pendimethalene); @ 2500 g ha-1, Premextra Gold 720 SC insert ignore into journalissuearticles values(atrazine+s-metolachlor); @ 2000 ml ha-1, and Sodium chloride insert ignore into journalissuearticles values(common salt); @ 5% solution and untreated control. Statistical analysis of the data showed that different herbicide treatments had significant effect on the mortality of parthenium weed. The post emergence herbicides, glyphosate and ametryne+atrazine at rossete stage provided 97% & 82% and at bolted stage 96% & 60% mortality of parthenium weed at 4 Weeks After Spray insert ignore into journalissuearticles values(WAS);. Among the pre-emergence herbicides pendimathaline and atrazine proved best with 10 & 16 plants m-2 respectively and inhibited the regeneration of weeds for a longer period of time. It is recommended that a mixture of glyphosate insert ignore into journalissuearticles values(non-selective herbicide); in pendimethalne or atrazine at their recommended doses can be used on noncropped areas for effective control of Parthenium weed.
