Abstract
A field experiment was conducted during rabi 2008-09 at Cotton Research Station, Sirsa of
Chaudhary Charan Singh Haryana Agricultural University, Hisar to evaluate the efficacy of pinoxaden
as tank mixture or sequential application with broad leaf herbicide 2, 4-D for controlling the complex
weed flora in barley. All the weed control treatments effectively controlled the weeds and gave
significantly higher grain yield than the weedy check. Post-emergence application of pinoxaden at 40,
45 and 50 g ha-1 alone provided excellent control of P.minor Retz. and A. ludoviciana Dur., whereas 2,
4-D at 500 g ha-1 proved very effective against all broadleaf weeds. Application of pinoxaden 40, 45
and 50 g ha-1 and 2, 4-D either as tank mixture or their application in sequence before or after one
week interval effectively controlled the complex weed flora without any phytotoxic effect on crop and
produced grain yield of barley equal to weed free treatment. No antagonism between pinoxaden and 2,
4-D was observed as shown by percent control of grassy weeds.
