A field experiment was conducted during January-July, 2005 to study the effect of integrated weed control methods in irrigated cotton hybrid. Pre-emergence application of fluchloralin at 1.00 kg ha−1 followed by post-emergence directed application of glyphosate at 0.80 kg ha−1 at 45 DAS recorded the least weed count (19.39 m−2) and weed dry matter production (124.70 kg ha−1) favouring higher seed cotton yield (25.34 q ha−1). Application of fluchloralin and pendimethalin at lower doses in combination with one hand weeding produced significantly higher seed cotton yields than application of these herbicides alone in higher doses.
