ABSTRACT
A field experiment was conducted during two consecutive years of kharif 2011 and 2012 at ARS, Banswara to evaluate bio efficacy of clethodim 24% EC against grassy weed flora of cotton.The experiment was laid-out in Randomized Block Design with three replications having ten treatments and revealed that, theapplication of post emergence herbicide clethodim 24% EC @ 60 g a. i. ha-1 + NIS + AMS at 15-20 DAS was effective in controlling grassy weeds in cotton resulting in to increased bolls plant-1(30.63) and boll weight (4.38 g), seed cotton yield (2178 kg/ha) over control but it was found at par with weed free check, clethodim 24% EC @ 48 g a.i. ha-1+ NIS + AMS, pendimethalin 30% EC @ 0.75 kg a. i. ha-1,fenoxaprop-P-Ethyl 9.3% EC @ 50 g a.i. ha-1,respectively. Application of clethodim 24% EC @ 60 g a. i. ha-1 + NIS + AMS at 15-20 DASwere recorded lowest weed population (20.33 and 21.93 m-2), lowest weed dry matter accumulation (14.88and15.03 g m-2) and higher weed control efficiency (50.14 and 61.61 per cent) at 30 and 60 DAS in the pooled analysis.
Key words: Cotton, Clethodim Herbicide, Weed Control Efficiency and Weed Index.
